I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

A:Windows 7 ACPI doesn't detect battery but battery is working

I had a problem similar a while back. Try this
1.Shut down the laptop
2.Take out the ac cord and the battery. Hold down the power for about 10 seconds to remove electric charge in the capacitors.
3.Put the battery back in and reboot.
4.Start windows normally, and See if the battery is recognized.

Hi there,
I have a Dell Inspiron 15R 5521. Since a while now my laptop is given me messages explaining my battery has a fatal error and needs to be replaced. I have been searching for a different solution than simply replacing the battery/adapter and I've seen that a lot of people had to update their BIOS. I currently have BIOS A07. When I try to update using the driver I've gotten from your site this window pops up and tells me I have to plug in my battery and adapter. Both are plugged in but I can't seem to manage to start the update. 
I hope you guys can help me,Dries Vanden Broecke

A:Battery not working

Hi Dries Vanden Broecke,
Download the A14 BIOS here -
Now, for the BIOS update to run, it is required that the battery be connected and battery should contain a minimum charge of 10% and the adapter needs to be detected in BIOS.
Having said this, Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point. Check the battery health in BIOS (if applicable).
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
Shockingly none worked that I found.
Only one thing worked for me to my surprise.
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
Worked with an off brand battery also.
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
Thank GOD for bringing the idea to remembrance!

I got the laptop checked by a repair company and they say the motherboard is ok. Is there a possibility that the battery is not working due to software / drivers issue?

Hello Alldayvikings28 and welcome to Seven Forums.

If the battery still has a charge left, you might try running a power efficiency diagnostic report to see what the health of the battery is.

You could also remove the battery and run the laptop on AC power only just to rule out a computer issue.

I have a new battery. The laptop is g560 working fine on AC adapter without battery in. When I put  the battery in the laptop starts draing the battery without charging. May be it will work if I uninstl the ACPI...thing  from windows 7 the problem is that impossible to turn on the machine with the empty battery  and the AC plugged in. Evry time switching on it tries to boot on battery ignoring the AC adaptor. I have no idea if the battery is charging when the laptop is turned off.

Me and my sister have the same laptop with windows 7 ultimate 32bit running on each one. The problem is my sisters laptop is not detecting the laptop battery charger when inserted. Her battery and charger works fine as I tested them on my laptop and both fully functional and even my own battery and charger does not work on her laptop.

When the charger is plugged in no message or charging icon comes up, just the normal battery icon. I'm pretty sure there is something wrong with the laptop.

any help please?


A:Laptop not detecting a working battery

Hello slizza and welcome to Seven Forums.

Could you post some additional information about the laptop like make and model? Sometimes a computer manufacturer installs their own software that controls how a machine will work. Just as an example, on a Sony Vaio they have what's called Vaio Care. This software can override the built in Windows 7 power plan settings.

In the meantime, you could compare the power plan settings on your laptop to the settings on your sister's laptop and make sure they're the same. You could also run a power diagnostics efficienty report to see if your sister's machine is showing any issues.

Power Plan Settings - Change

Power Efficiency Diagnostics Report

You could also open Device Manager and see if there are any warning symbols for the battery. This could indicate a driver issue.

I recently bought a new charger cable for my hp compaq 6720s and since then my battery wont charge and when it is plugged in the mains (the only way the laptop works) the mouse on my laptop doesn't work either, i've also tried using an external mouse but that doesn't work also. is it the charger i bought which is faulty or the battery, or even just the laptop itself?

Any help at all will be greatly appreciated, thanks.

A:battery not charging and mouse not working

There could be a problem internally, with your laptop such as the motherboard, causing both the keyboard and battery problem.

1.) Have you tried removing the laptop battery, and testing it with just the adapter plugged in to see if it still works without powering down? If it powers down while plugged in-with the battery removed, there is a problem with the computer itself or the power adapter.

2.) When you say your are using an external mouse, is it a corded mouse or is it wireless? (It is best to swap with a wired mouse instead of a wireless for troubleshooting purposes)

I'd suggest you check Battery's status and health in the Battery Meter App. Please right click battery icon at taskbar, and then click on battery health. It should say Your Battery Is Performing Normally, if it say anything else then you most likely need a new one. Secondly, check battery status, if there's a checkmark in box by Enable Dell Extended Battery Life then uncheck it and restart computer.

Hi guys.I've search the forum but I can't find anything relevant.I don't like leaving my laptop on charge all the time and I sometimes forget to switch the battery charger on and Windows shuts down.Now in Control Panel - Sounds you can set various sounds for various operations I made my own Chargebattery.wav and enabled it for Critical Battery Alarm and Low Battery Alarm and they both test ok. When the battery gets low it doesn't play the wave file. It does show the low battery tooltip in the systray but you can easily miss that.Does anyone know why it doesn't sound on a low battery or am I missing something in the sound settings?I've downloaded Battery Meter Gadget but thats only a visual warning so you would have to have the sidebar on top all the time plus it doesn't play any sounds?Cheers.

A:Need the charge battery sound working?

Does no one have any comments on this?I made the Chargebattery.wav with 2nd Speech Center as the default Windows Battery Low.wav and Windows Battery Critical.wav are just bleeps mine says your battery needs charging. I also made a Trash.wav to empty the recycle bin that says your recycle bin has been emptied and that works great. If anyone wants these wav file let me know?The Battery Meter does play a few bleeps which is better than nothing.I put back the default Battery Low.wav and Windows Battery Critical.wav but Battery Meter still played the beeps. I removed Battery Meter and tried it again and it still didn't play the default sounds it just shows the yellow message at 10 minutes and the red one at 6 minutes so this system for playing sounds is obviously crap.

Hi guys, I have a Tecra A10 0n Win 7 x64 Pro and has been working perfect for ages, all of a sudden the laptop went into hibernation and will now only boot up with AC plugged in.

The battery is fine as I have tried it on a different laptop without issue.

When I try to boot laptop without AC connected it loads to the Toshiba splash screen for a couple of seconds then dies.

Has anyone else had this or have an idea what the issue could be. Latest BIOS has been on for a while and all correct drivers are installed.

Laptop runs perfect with AC connected but tries to hibernate as soon as AC disconnects.

Could it be that the laptop cannot take power from the battery for longer than a couple of seconds?

Any help is greatly appreciated.

A:Tecra A10-14P Wont run on a working battery

> Laptop runs perfect with AC connected but tries to hibernate as soon as AC disconnects.
For me it sounds like the battery charge level is very low and that the power management of the Win OS set the notebook to hibernation mode due to charging level.

Possibly the notebook does not charge the battery properly.
If you said that the battery is OK (don?t know how you test this) then there must be a issue with the battery charging system. This means that the motherboard is not OK.

However, in your case I would test the notebook with a new battery to be 100% sure that this issue is not related to a faulty battery.

And what was the cause of this leak? I handle my computer really carefully and don't leave it plugged often. Thanks!f

I believe your system has the Intel HD Graphics, so  if that is the case, open up the Windows Control panel, and check for an Intel HD graphics control panel.    If the present, it usually has its own power management settings in Windows 7, and if so, set it to maximum performance when on battery and see if that solves your problem.     Other video card manufacturer may have similar power  settings as well if yours is not the Intel variety.    Other than some form of power management issue, I cannot see any other reason battery vs AC should make any difference.. Good Luck,

Hi.  When I'm working on my Flex 3 on battery only, after about 20 minutes, the screen will "turn off."  I use quotations because the sreen turns black but it is back-lit.  Sound still works.  No buttons get me out of this frozen state and I have to hard restart the computer. Anybody else have this issue?  Computer is 1 month old. Thanks!

It would hang up when running the bios and stop with the error message no mouse, no keyboard or keyboard error. I was able to get the mouse recognised but not the keyboard. The cmois battery was removed and replaced and now there is no video. I am not sure what this computer is running. Theres a digital readout on the front that says 200 when you start up. It has a diamond video card. When I power it on the cpu fan works power supply works, theres no lights on the floppy or on the cdrom that light up. Any suggestion on what to do to get video back and resolve the original keyboard error message. I did try to boot from a floppy before the batteries removal and that did not work.

Once I plugged in charger while my notebook was turned off.
It lighted Plug LED and Battery LED was blinking after 3 seconds.

I reinserted battery and it charged fine.
One day I was using my NB200 and it run out of charge, I plugged in and same thing happen but even after reinserting battery it won't start.

Plugging in it for long time doesn't heats up battery nor notebook. I can only start it without battery plugged in. Inserting battery shuts down PC after 1 seconds and LED of battery again blinks after 3 seconds.

What does it means? I tired putting battery in fridge because I read on internet it might fix but no luck.

Any idea how can I fix it.

First of all you have to know that the notebook should run properly without the battery but with connected AC adaptor.
Even if the battery would be faulty or empty, the connected AC adaptor should supply power and you should be able to power up the notebook.

In case this isn?t possible, I assume an power supply electronic malfunction.

However, you could test the following workaround:
Try to power up and to boot the notebook without the battery.
Then go to device manager and uninstall the following entries under batteries:
- Microsoft composite battery
- Microsoft ACPI compliant control method battery

Then reboot the notebook.
Power OFF again and insert the battery.
Power On the notebook and check if the unit would run properly.

Of course it would be also recommend testing the notebook in connection with another good and tested battery.

I didnt use my laptop for 2 weeks and when I finally get to use it, an error message shows up on startup saying of an hp battery alert where the storage capacity is supposedly very low and now it is not charging. There is also the case of the keyboard not responding if left idle for a while and will only respond if the whole laptop was restarted. It was perfectly fine before so i used system diagnostics and ran an extensive hard disk check and i got this: failure ID Q09K2F-00086P-MFKR6J-61D603product ID G2G88PA#UUFHARD DRIVE 1 please help. thank you.

I ve been having a strange problem with the battery for my Thinkpad laptop I noticed Battery Stopped Working Thinkpad Suddenly the other day that Thinkpad Battery Suddenly Stopped Working it wasn t charging when I plugged the AC adapter in Eventually it ran out completely and would not charge at all This happened very suddenly it was working fine a week ago If I have the battery installed and AC attached and hit the power button the system will start up for a few seconds and then shut down Sometimes it will randomly start AGAIN for another few seconds and then shut down The only way I can get the computer to run is with the battery removed and AC adapter attached If I start the computer up with the AC adapter attached and then insert the battery the computer immediately powers down I really want to get this problem resolved I m hoping that it s just the battery itself but it seems strange that it would stop working so suddenly From my experience laptop batteries tend to lose their power over time And even if the battery was no good shouldn t the computer still work as long as the AC line is connected I have no problem replacing the battery I m just not certain that this is the real issue It seems that the AC adapter works fine Is this likely just a battery problem or is it possible that the motherboard is damaged nbsp

A:Thinkpad Battery Suddenly Stopped Working

Hi Dan and welcome to TSG.

I assume your Thinkpad's warranty has run out.

It could be a problem with the motherboard power circuitry but that would be expensive to fix.

As the charger looks ok the easiest and cheapest thing to do is to try a new battery.

Sorry I can't be more specific.

I have a HDX16 laptop running windows 7. The battery is a year and a few months old, and yesterday was giving me at least 50 min of battery life. However today, it wont hold a charge at all and my computer shuts down completely whenever the power supply is interrupted for a millisecond. I ask because this is the second time a battery has suddenly stopped working on me and I am wondering if there is a reason for this. I tried to check the battery condition by hitting esc + f2 when my computer starts up, but there is no battery check option. Any explanation or advice would be greatly appreciated Thanks for your time. 

A:Battery suddenly stops working - computer shuts off despite ...

Hey Aitchpk,  I'm sorry you're having a battery issue. I would suggest running a battery check using HP Support Assistant if you have it installed on your computer.  You could also try using this standalone Battery Check. Do you have any issues like this if you operate the computer without the battery and just have the power cord plugged in?

My machine is getting older still works like a champ but some wonky things are happening power working is battery pc tho failures even packup during restarts Last week during a storm the computer restarted I have always used battery backups with avr and it really shocked me It never gave me an error just restarted itself So I checked it and my battery back up seemed to pc restarts even tho battery packup is working during power failures not be doing its job I unplugged everything and plugged in a lamp and then unplugged the back up and the light flashed I could not remember when I bought it but I was sure it was over years So I bought another one well the same thing is happening and this time I installed the monitoring pc restarts even tho battery packup is working during power failures software and did a self test and the computer still restarted itself and the battery back up says it is working fine I changed the outlet the back up was using too the test with the light on the new one seems to show the back up is working too I did have a new power supply installed before I replaced the back up cause it seemed the fans were not working in it that was determined at the place I had it installed it was not working but I didn t have time for a diagnosis And now I even have a weirder problem too half my icons that used to show up in the task bar are not there now the things I always closed I am happy about but now I don t have icon for my usb things nothing to click to safely remove hardware The things that have changed in the last bit of time is that I had a problem with my avg security suite it seemed that when I started to do anything using a bunch a bandwidth I would lose my dialup connection and I asked the support if all the filters and stuff running could be causing that Just asked they suggested upgrading to that might solve any of those kinds of problems cause it was supposed to be less resource intensive Dumb me did it Now I am talking with their tech people about why this version s firewall will not configure One change but that major change was after the power supply change and the battery back up change To install the software for the battery back up I added a powered usb hub and I think that is when my icon for the usb disappeared but not sure seems that the some of the icons had been intermittently being gone since I installed the new avg stuff But the weirdest thing is other than that stuff my machine is working well It is a velocity micro gamers edge model p gigs ram pro still as snappy as it was when I got it back in sept of The main reason I noticed the fans in the old power supply not working was because I have temp gauges for the ambient processor and video card installed and I know they are not really right but it gave me an idea of what was going on and the temps had increased like degrees c Checked and they were not moving I just really worry about the restarting thing I never get an error or anything just restarts I know in the last few weeks it has done that more than in the whole time I have owned it I know all this stuff is really weird and probably not connected but gees this has been the best computer I have ever had and believe it or not nothing has ever been done aside from the power supply and a harddrive failure right after I got it no reformatting or anything Maybe that is what is needed but since I don t do that myself my experience is no matter who I get to work on my machines they are never ever the same I would rather just buy a new one I guess mainly does anyone have any idea of these things sealing the doom for my machine Like I should be ready for the worse nbsp

Hi Need some help, I have an inspiron 5100 that I bought couple of year ago. few month back I noticed that the machine is not charging the battery when the laptop is on. as sson as I shut down and turn off teh laptop, teh charger stats working on the battery. So I don't beleive it is a battery problem but rather a charger one, I'm wondering if someone know if it is a software related and how to fix it.


A:Dell Inspiron 5100 Battery Charger not working

Check very carefully for full contact from the charger points, and the best way to clean them is with a pencil eraser, followed by denatured alcohol and a queue tip. The contacts do become weak or bent, which can cause the problem.
There is no software that affects that model, but there is a chip in the battery that counts the number of full charges. Onces it reaches that magic number, it stops further charging even though good otherwise. This is to prevent fire and other damage as the battery ages.
Otherwise, you need someone with experience using a soldering iron, to replace a couple of doohickies inside the case.

I was previously using Win8.1Pro and the charging would stop at 95% (plugged in, not charging) and after charging would go below that level, charging would kick in like 90% (plugged in, charging). However, now i'm using Win10Pro and the smart charging feature isn't working. I've tried google, but to no avail. What worries me is, keeping the charger plugged in at 100% all the time will wear the battery out and plugging and unplugging all the time is just a nuisance!How can I revert back to the previous state?  I've tried HP AC Power Control, but it's not made for Win 10 as it just unresponsive even after we apply and okay and frankly, it's just a poor software.  HP should learn from Sony or Dell, their Battery Care Function and Battery Life Extension are very much user friendly.I would appreciate help in this matter. Thanks.

my dell d600 wont charge batteries

I have purchased a new power supply, new battery

nothing worked so I took it to get it repaired and I was told that there is a problem with some connector in the montherboard I guess thats what detects the battery..
and in the bios it reports the battery as unknow as does windows
does anybody know if this is DIY job? instead of spending money on getting it repaired?

also is there a way to recharge a battery without have it inserted in the laptop?


A:Dell D600 laptop problem - Battery not working

I wouldn't waste any more money on a laptop that old. It's unfortunate that you spent money on a new battery and power adapter.

There's no point in charging the battery externally, which would require yet another purchase if such a device exists for that model battery. The odds are the problem is with the laptop itself.

Bought my wife this computer for Christmas.  Apparently Dell has combined the power indicator light/hard drive activity light/ and battery status light into one single light on the front edge of computer.  My concern is that the light only comes on briefly when I first plug  in the power supply, then it goes out  and never lights again.  Even when the hard drive is writing or reading the light doesn't come on to show activity.  Is this normal?  I'm concerned as this is one way I've used to determine if things are happening on my computer as they should be.  If  the light is not designed to show hard drive activity when it occurs, what use is it?

Hi All,

my 2 yr old U920t laptop/tablet satellite ultrabook has poor battery life. The battery will only last a maximum of 2 hrs before requiring recharging under normal word doc/excel data entry.

Any ideas on how i can improve it?

The Toshiba pc health monitor function continually informs me that I need to replace the battery due to normal wear and tear but I thought the battery being an 'internal' item means it cant be replaced?

If anyone can offer some advice that would be great!

A:Satellite U920T - short battery working time after 2 years of usage


In my opinion there is no some kind of ?rule? or ?norm? about battery life in general. On some machines battery hold capacity for longer period of time comparing it with other notebook models.
Fact is that over time battery will lose the capacity and result will be shorter working hours.

You can try to increase working hours changing some power options and shutting off some useless background processes.
Many newer notebook models have newer design where battery cannot be removed so simply and it is placed under the bottom cover but it can be replaced too. One day when you need new one contact nearest Toshiba service provider and they can replace it for you.

Battery Issue - Lenovo V570 (Laptop) - Battery Model L09S6Y02

First off I for the most part do not use the battery. It is normally detached from the laptop. I only attach it to periodically charge it and test prior existing charges' performance.

O.K. here is the problem. I attach battery attachment, computer does not make it to the window screen more often than not. When it does, it freezes at the please wait loading screen.

I rarely use the battery at all, but I want all my equipment up and functional. It's life should still be good for I periodically recharge it. I think since I've had the laptop I've only recharged it a total of 6 or 7 times and that's been a year or so.

I, for the moment at least have the battery working power adapter attached. What did I do? I uninstalled Avast (freeware version) ?

I learned from prior experience that running two of any system utility software can cause problems, but it normally restricts itself to what it is protecting. Then I remembered: "If you remove the possible whatever is left however in probable must be the truth."

Next phase of testing is test the battery on it's own.

After a round of Windows updates, I went to turn on my laptop and recieved the "Primary internal battery (601)" error.  After this screen, however, Windows would not load.  I have tried taking the battery out and 'draining the charge',  and starting up the computer plugged directly to AC with no battery.  Windows still does not load.  The start-up test in the diagnostics menu said the battery needed calibration, however when I go to run the battery test, it gets to "waiting for battery to charge" and exits out of the test without giving me any results at all.  Currently when turning on the computer I no longer get the "primary internal battery" error, it just goes directly to a black screen with blinking cursor.  Any help is appreciated, I'm completely at a loss here!

A:Dell E1505 - good battery "not working"?

Your laptop Dell E1505 sounds as though it may have either a motherboard or just contacts issue

Regarding the contacts, make sure both the battery and if possible, the motherboard contacts to the battery are clean (usually blowing out all dust)

Regarding the motherboard, firstly check the warranty status and also have a look at extending expired warranty. As this does sound like a hardware fault.

Hi Utkarsh. I Actually FIXED this problem months back. and I exactly want to help you on this so that you can fix it yourself too..
the problem which is creating your battery to show an exclamatory mark is your power settings.
so follow these steps to get rid of that sign and a perfectly working battery.
1) Click on your battery icon (left click) you should see an option called " More power options" at the bottom of the popup.
click "More power options"
2) Now you will be taken to your control panel where you can see all of your power plans and under each plan, you will see an option called "Change plan settings"
3) Click on "Change plan settings" for your active power plan. Now you will get redirected to another control panel window, where you can see two kind of power options to get adjusted. that is, when you battery is plugged and when your battery is unplugged.
4) Don't touch those options, just click on "Change advanced power settings" at the bottom left of that window. THIS IS THE AREA WHERE WE NEED TO FIX!
5)After you click on "Change advanced power setttings", you will see a POWER options popup, go to the bottom and then you can see something called "Battery" with a plus sign on the left. click it.
6) Now you just have to change the levels for the following values
                   --> Critical battery level ( you can change it to 10%)
                   ---> Low battery level ( you can change it to 20%)
So I hope this works!
Reply me back when you've succeeded fixing it.

Ok this might be might not (COMPAQ M2105)

I ended up replacing my motherboard for a model with more features (SD readers blah blah).

I took it all apart and put it all back with the new board when i go into windows (and even before while booting)...the orange lights would come on for a second...then beging to flicker

while in just will either not charge the battery..or flicker from AC to battery

i CAN power the unit on with the battery alone, and i CAN power the unit with the cord alone...

lastly, my old motherboard (which had a HD connector problem)...still WILL charge the i'm sure its not the battery...i don't think...

i also dont' think its the AC adapter since it is the same piece I used on both motherboards.....

what to do................

A:compaq M2105 laptop - battery will not charge, flickers from AC/battery

Hopefully you are experienced in working on and repairing laptops/notebooks... and you carefully handeled the replacement motherboard and didn't damage it. Repairing laptops takes considerable skill and caution.

It does sound like the "new" motherboard is bad unfortunately. How did you handle the "old" operating system restore to the "new" motherboard?

Hey @EnigmaDimirti, Welcome to the forums. I'm here to help. I would strongly suggest Testing and Calibrating the Battery. Should that not solve the issue, I would suggest calling in for support to see about replacing the battery, as it should not be displaying "no battery is pluged in" when you run a battery check. Please use the following and create a case for your issue and contact HP. If you live outside the US/Canada, please click the link below to get the contact information for your region. If this helps, please hit that Thumbs Up, and Accept as Solution. Cheers,TechSurge.

When I switch on my laptop today, I got the warning "Warning battery cannot be identified. System cannot charge the battery." If I plugin my adapter, laptop is running on AC power, if I remove the plugin, laptop is turned off. I have downloaded latest BIOS update but still the problem persists.
Details: Dell Inspiron 3521, Windows 10, latest BIOS V14.
Please help!

Is the battery OEM or an aftermarket battery?  How old is the battery? I know of Windows 7 OS having issues with recognizing some batteries and were relatively easy to fix.  I do not know if it carried over to Windows 10.  I will have to look up the article to find any relevance.

As a follow up, I'm just curious if this is a widespread issue?  Anyone have loose battery in their x230 / x220?  I'm not talking about it falling out...but just a few millimeters of wiggle room.  Basically when i pick mine up or place it down, I can feel / hear the battery move.  I'm just trying to get an idea if this is a real problem or thats just how every thinkpad is.  I called support and they are sending someone to replace the base panel and we'll see if that fixes it.  I'll update this post when it get's replaced.   Edit* I also asked the lenovo support rep if they had heard of this issue and they said no, never.  I don't see how this is possible as if you do a google search for thinkpad loose battery there are many results.

My W540 is asking me to consider replacing the battery. The original battery is a 57++, 9 cells, 11.1V, 8.96Ah 100Wh, Li-ion00 battery. Searched on ebay, cannot find an exactly the same one.  The closest match one is this:  Some 9 cells 57++ is 10.8V, 9.21Ah and Li-ion 20  ----- does this one is better than mine original because of its lower V?----- do you have a reliable seller from ebay or amazon to recommend ? From the Battery Maintenance window I found there is a Battery Health Mode feature somewhere. But where I can find it??

Hi out cuts battery power, on laptop battery good my girlfriend in Beijing has an Acer Aspire S latop She bought a new battery for it laptop cuts out on battery power, battery good a while back and told me it was no good I was in Beijing recently messing around with it and found that actually the battery is fine lasts for gt hours but when unplugged and running on battery power the laptop often just cuts out suddenly loss of power I took the battery out and had a look and cleaned all the connections but they seem fine The next part is the strange part and which I hope might give someone a clue as to what s going on When it cuts out it will never restart again unless the mains power cable is plugged back into the laptop As soon as that s done and the power button is pressed it starts up again and the cable can be taken out immediately I mean immediately - you can plug the cable in push the quot power on quot button and pull the cable back out in less than a second and it will start up and run fine on battery again until the next time it suddenly cuts out without warning Because any unsaved data is lost and because the laptop cannot restart without the power adaptor this very portable and light laptop is now reduced to having to be kept at home all the time and plugged in which is exactly the opposite of what she bought it for Anybody have any idea what the problem could be or suggest some tests that could be done to find out She took it to a local computer shop but the guys there had no idea Thanks in advance for any advice nbsp

Recently I noticed that the amber LED on my HP Probook 650 G1 flashing constantly, even when the laptop is powered off.   The System Tray battery indication is 100%, fully charged, when on AC power and 100% on battery power shortly after undocking.    I find the Probook won't power up if AC power is not available (no response when pressing power button) but remains powered when I remove it from the docking station.    Have the electronics that control this LED flashing and power up when not on AC gone bad?    Is this an indication of other failure? thanks

Today I found this page in Toshiba Spain website: , and my battery is affected.

I called Toshiba and surprisingly the answer has been: *Yes, your battery is included but we no longer change them. If it has worked for some time then it should not fail.*

I have read many times the information in the mentioned web page and *I can't find the established period for the change*, and the most important thing is *it encourage me to remove the battery to prevent damages.*

I was expecting something else from Toshiba.

Hey battery of my notebook was affected too and it was changed 3 years ago. At this time the whole exchange program was ongoing.

Sorry but after so long period of time I presume the whole exchange program is at the end and out of date.
If you didn't have any problems with the battery in the past I don't think you will have it in the future.
When you will notice the battery is at the end by new one and everything will be OK.

I am new at this stuff and I seek help from all those who can give it. Ok so my first charger stopped working and I bought a new charger. The charger worked great for a few months after purchase. Until one day the charger stopped charging on and off. I unplugged it a few times and then it stopped working. I let the battery die after. I am guessing that it stopped working because i may have screwed up the charger socket by tripping on the cord thus pulling on it im not really sure anymore. The laptop is in a bad condition, it's four years old i think but it can still run. The battery is the same not change. HELP ME for I am an *****

The battery on my Latitude E6540 has become a little loose. This maybe normal with time? I'm not sure. The battery still charges and performs normally. However, it seems one of the springs in the battery release latch has broken. Thus, I cannot remove the battery to inspect the looseness. The battery wiggles a little. Any suggestions would be greatly appreciated. My latitude is still under warranty. As I work at an academic institution, the laptop is also registered with the institution. I figured I'd ask Dell first since the warranty is still in my name. Much thanks in advance.

Hi, When I first got my laptop, I would click on the battary icon in the tray and it would give me a time remaining estimate as well as the percentage.  I have since had to reinstall windows 8.1 and no longer have the battery time remaining estimate, just the percentage.  I have installed all the latest drivers from the support site and everything works fine except for that. I have tried every version of the BIOS available on the support site and reinstalled serveral times.  I also tried running a battery check which came back fine.  Any idea on how to fix this? Thanks.

A:No Battery Time Remaining when clicking on battery icon in T...

Hello tm200 The Battery Time Remaining information has been removed from BIOS F.11. The battery time estimator basically looking at what you?re doing right now and give an estimated remaining time. It was common for the readout to go from 8 hours to 16 hours in a matter of minutes. This might cause more customer confusion than it would solve. The trend of mobile devices intended last for whole day is try not to estimate their battery life. For example, iPhones, iPads, Android phones, tablets, etc. all don?t try to estimate. They might give insight into your past usage, but they won?t try to project the future.  ThanksWayne

I have just replaced my CMOS/BIOS battery today, as , I have faced some critical problem regarding regular BIOS date/time reset after system shutdown. But I want to know how do i recognize, that my new batter is totally ok or functional.

Battery Meter gadget shows that "battery Not charging"
Is it a gadget problem?

Is there any method available so that I can track that my new installed CMOS battery in PC is working fine?

Please help me.

A:Battery Meter shows CMOS battery not charging

The battery you have replaced is solely there to maintain the clock and other BIOS settings (if you have changed them from their defaults). It will not prevent you from booting your system if it is dead/missing; all it means is that you will have to enter the BIOS each time and make the correct settings and time. This battery is not rechargeable.

Do you still have to enter the correct time, or is the BIOS maintaining this now you've changed the battery?

I was trying to read the chraging cycles of my battery, but I didn't find any software which was able to provide this information. Lenovo settings app and the the new version of Lenovo Solution Center don't display any information regarding the battery. Some people mentioned, that settings app should be able to set charging levels and to display battery info. But there's actually no battery settings menu available.I was trying some other software, but it seems to be impossible to access charging cycle registers. Is there any solution for proper battery management on Win 10 anniversary?

Vista is retrieving me the error message that it is not able to retrieve the power parameters.
Do i need to install a softawre to allow me to access those parameters ?

Thanks for you feedback,



A:Battery - Vista is not able the retrieve the power options for the battery


To be honest I have no idea what you are talking about.
The Vista power options are a part of the Vista OS and you don?t need to install anything.

But on Toshiba notebook the Vista power option would be extended by some Toshiba power options.
Are you speaking about this Power Saver options?
If yes, then I would recommend reinstalling the VAP (value added package) because these power options are a part of VAP.

I am becoming more and more concerned about my laptop's battery each and every passing day. When I check the bottom right of my computer screen to check if my computer battery is completely charged, it says "0% available (plugged in, not charging)". I have had to buy two new batteries because of the same thing and they also read "0% available (plugged in, not charging)". When I unplug my laptop from the power source, it turns off automatically. I cannot even bother calling Dell to check this issue for me because I bought this computer off the street for $35.

My question in general is how do I get this problem fixed and how do I keep an eye on how my laptop computer charges correctly (or not)???
