Laptop not working on battery

Q: Laptop not working on battery

I have a Toshiba A75 laptop. My battery had died and I got a new one but the laptop wont work on battery. It works on the AC adaptor. I got replacement batteries twice but same result. 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? When I put in the battery, it shows the charging light and charges to 100% but as soon as the power goes, the computer goes out.

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.

Power Efficiency Diagnostics Report

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

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.

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.

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.

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.

A:Bought a new dell battery and still my laptop battery doesn't charge!

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.

It's so strange. Today when I turned on my laptop, suddenly, there was a message that my battery has problems so the computer might shut down suddenly. I tried different strategies, like uninstalling the battery driver, or letting the computer completely die. When it turned off itself at 6%, I turned it back on, and it was at 2 minutes battery life. Then in a few minutes, it said 4 minutes battery life for 6%. Now, it's passed an hour, and it says 3 minutes, but changes sometimes to 1-4 minutes. The battery meter is completely wrong, and I don't know what to do since it is closing the computer way too early. I'm still not sure what the problem is. Please help me.

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................

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?

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)???

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

Hi Guys,

I have replaced the battery of my laptop after using it on AC supply for about year after my old battery died.

I get this error message.
"The AC power adapter type cannot be determined
Battery may not charge.
This problem might be solved by:
Connect a Dell 65W AC adapter or higher."

But I am using a 65W Dell Adapter that I got with my laptop.
BTW, I tried the steps for disc AC >> Start>>Uninstall MS ACPI >> Insert battery>> Restart. This process did not yield any favorable results.

Please help!!!

A:Laptop battery issue ??battery calibration??

i'm afraid the battery calibration program is only used to initialize new Li-Ion batteries which need to be prepped with an initial charge-discharge cycle.

It sounds to me like you have a battery composed of 32 (probably AA sized) cells.
One of those cells has died and hence you see only 97% charge. Unfortunately losing a single cell prevents current from entering or leaving the battery so your battery will not discharge correctly therefore shutoff without discharge.

I think you need a new battery. Although it may be possible to replace the single bad cell, other cells may be degraded also - if one cell failed, why not others? unit could have been exposed to heat etc.

Although I was an engineer for Gould, I am not a battery expert!

good luck!

Since i bought a new laptop E7270, is it allowed to use my power adaptor my old Dell E6420 also for the new one?   If so i can use one adaptor at home and another in office and dont need to carry the power adaptor always.
Will this impact the battery performance of the new laptop?

A:If it is possible to use the power adapter of E6420 for my new laptop E7270? Will it impact the battery of the new laptop?

If the connector fits (it may not - the older systems use a much larger barrel connector than many of the new ones), AND the power (wattage) is equal or greater, yes.

Hello ...
I have had a Toshiba C850-A965 laptop for 4 years
and it's been working perfectly
untill one day recently, a message poped up saying that there's something wrong with the battery and should be replaced, but it was still the same, works for an hour and a half approximately
But, I went ahead and bought a new battery, the message disappeared
and i fully charged and then started the laptop
it worked for about 15 mins and then it shut down ( like u took the plug off from a desktop computer) without any warning
when i turned it back on, it was still fully charged !!! and the shutting down happend again and again :(
the old battery is still working fine
so that must mean that there's nth wrong with my laptop right? and the battery is bad?
please give me your opinions
thank you for your precious time

A:laptop battery problem, laptop shut down suddenly

Could still be a faulty battery. It can read the correct voltage off load, but as soon as you put a load on it, it takes a dive. The battery status symbol is just that, a symbol. The only foolproof method of proving it is to replace it with a known good battery. Do you have any good friends with a similar laptop ?

A:Laptop Battery Doesn't Charge if Laptop is off

a bios update is often needed when using a different battery than what the laptop was designed to use, and since you bought a generic battery, i highly doubt that Sony will provide support of any kind for it.

Check Ebay for actual Sony brand batteries (not another generic), you can get them on Ebay for 1/2 (or less) the price that you would pay in a store or from Sony

I have an HP Probook 4540S.

I don't use it that often and when I put it away, I make sure the battery is at 100%.

Today, I went to use it, and it would not power on.

I plugged in the A/C adapter and it powered up and showed the battery at 0%.

I called HP and they said that is normal and if I'm not going to use it for more than a week, to remove the battery.

I went to the HP forum, and they said just the opposite- The Mod said it has to be a software problem or a crappy battery.

Which is correct and would removing the battery when not using it be okay?



A:Laptop battery draining when laptop is shut down

Batteries do lose a certain percentage while being shutoff, usually 2-3% but it can be higher. The battery could be completely normal or it could be going bad. Typically this is from heat or poor charging habits (don't worry, everyone does it).

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 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 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.

Does anyone know why it doesn't sound on a low battery or am I missing something in the sound settings?

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.

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.

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.

A:Battery suddenly stopped working on NB200-10z


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.

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.

I have exactly the same problem. Works fine when plugged in, but absolutely useless on battery, due to this random "black screen". My screen too is backlit, but the only way I have found to "wake-up" the screen is to reboot the computer. My Flex 3 came from Costco, and I am planning to return it.

A:ThinkPad X260 on battery & powerpoint not working

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,

I noticed that in the past 2 wks or so that my Laptop battery suddenly refused to charge fully. And the problem seems to be getting worse. 1 wk ago it was charging up to 69% and stopping. And now it's only charging to 52%.

Any idea what caused this problem and how to reverse it if possible? I think I've generally kept my battery in good condition, not charging it when 1/2 full etc. And this problem appeared quite suddenly.

Hey everyone. I have a couple of questions regarding laptop batteries. i looked around on how to maintain the battery but never really answered some of the questions i have in mind

When your laptop battery is full is it best to unplug the laptop from the Ac adapter and work on the battery until it needs recharge again??

Or is it better once the battery is full then remove it from the laptop until when actually wanting to use it??

If anyone can answer these questions and provide any further advice on how to keep my battery happy then pls let me know

Hi all,
Just had to format my TIME Traveller laptop and now it won't run on the battery.
The charging light doesn't come on anymore. Its as if I've wiped a program out or something.
Any ideas please.
Thanks for your replies.

Sound like your battery is dead, I am afraid.

With the cheap laptops the price they are now, if you can't easily get a new battery I would think about just getting a new laptop. But consider that a last resort.

Does anyone here know how long a laptop battery should really last???? I have just bought a Toshiba Satelite A75 226s P4, 3.06ghz, 512 ram, 60 gig hd, running windows xp home. I called Toshiba and they said the battery is running normal at only 60-80 minutes because of the processor speed, All I have been doing so far is my email and surfing a couple forums. I have Norton antivirus and security & spybot and make sure that everything is updated and checked regularily. So if anyone knows if this is really a normal amount of battery time please let me know. Oh (I have the power management set to long life.) and have been to blackviper and did all the tweaks he suggests. The computer is running great but the battery stinks.

A:Laptop battery

That model uses a "desktop" processor chip, not one optimised for long battery life.

The "long life" chipset at the moment would be the Centrino, which uses a Pentium - M CPU at a lower clock speed.

You cant have 3 GHz performance AND long battery life. Most laptop users are not away from the power supply for very long, and those that are buy the hardware suited for the task.

Hello, I bought my first laptop the other day. A 17'' HP Pavillion running Windows 7. My question is can I take out the battery and just run it via the power cable? I heard you can with some laptops but not so with others. I don't need to bring the laptop with me places so I will be using it like a desktop PC for the most part. I assume that charging and discharging the battery in time will wear it out, so if I don't need to use it on the go I might as well give the battery a rest.

View Solution.

A:Can I use the laptop without the battery?

Many people now use a laptop in much the same way as a desktop, at work or home.Such as the laptop is plugged in and rarely/never moved or unplugged nor completely shutdown,simply allowing it to go into sleep mode. This type of use does seem to contribute to battery decline from posts we see here a lot. HP & other manufacturers do recommend removing the battery in such instances. Since I do unplug/move mine at times I keep the battery in and make sure to unplug and allow to discharge & recharge periodically. This has worked well for me.

My friend said it's better to take the battery out while you're using the power adapter because if I keep the battery on the laptop, the battery will be leak sooner.
is that true?
or is it okay to keep the battery on the laptop even though you're using power adapter?

I was just wondering if anyone has a theory as how my laptop's battery could just suddenly stop working while i was away on vacation.

I have a 2 year old HP dv6600 in very good shape, i have taken very good care of it and it has had no problems, i went away on a 2 month vacation and now when i came back it seems like when i plug in the charger the charge led light on the computer lights up and the blue light around the contact point, everything as it should.

in windows the tray icon says charging, but current capacity is at 0% even tho it says always says charging and the icon keeps animating.. but if i unplug the charger the computer dies immediately.

A:Laptop battery

It sounds as though the battery has completely died, and is no longer capable of holding any charge. The only cure is to replace it. If you go on a vacation again, and are not taking your laptop with you, remove the battery to prevent it from discharging to a point where it will no longer charge.

If I turn all the settings on my laptop down then i can just get three hours of battery life. I'd like more and have heard of 12 cell batteries.

-How do I know which battery to get?(laptop is an asus X83VB and has a 6-cell battery)
-Were do I buy the battery?(best buy, asus website, battery store?)
-Will a battery with more cells(???) actually increase my battery life by very much?

A:Laptop battery

Theoretically, battery manufacturers can manipulate the numbers of cells and still not increase the battery's capacity. Of course looking at the number of cells is usually an indicator of its capacity (emphasis on "usually"); but, the one number that should always be an accurate indicator of its capacity is the amp-hour rating, usually expressed ah (amp-hour) or mah (milliamp-hour). A milliamp is one one-thousandth of an amp.

2500 mah and 2.5 ah are the same.

I got my last replacement battery from and I'm very satisfied. I went for the higher-capacity 6600 mah battery as opposed to the available 4400 and it holds up my heavy-duty laptop over two hours. I don't know how much over two hours it will go as I just haven't pushed it any further.

As to whether you should get a battery from the computer manufacturer or an after-market supplier, the batteries from the manufacturer are just as good and no better, in my opinion.

I just got this laptop about a week ago and have been extremely pleased with it so far. But, I have noticed that the battery life is very short. When I first got the laptop, I charged it completely using an external power source and then let it drain down to 7 percent, and then I charged it again, repeating this cycle a couple of times. Today, still unsatisfied with the battery life, I ran HP support assistant and did a battery check. It came back with the result that the battery needs to be replaced?? So, how is my laptop running in the first place, and is this battery check reliable?

I'm looking for an internal battery for my Sharp Actius A250 laptop. I haven't gotten a response from Sharp, and I suspect they'll want a king's ransom for one anyway.

The battery I'm looking for is a Panasonic CGP-E/404A, 14.8V 1400mAh Li-Ion.

It's actually made up of four Panasonic CGP345010 3.7V 1400mAh Li-Ion cells, so I could actually tape one together with four of those.

If anyone has a source for these, I'd be grateful, a Google search turned up no sources for purchase.

I have this HP dv7-1243cl laptop for the past 2 years and have never used the battery connection since I am always hardwired. I received a message which said a battery replacement is suggested.

Since I never use this function can I continue to hardwire without any problems.


A:Laptop Battery

Keeping the battery on A/C power all the time definitely shortens battery life, but if you never take it off the adapter, that doesn't matter. You could remove the battery and the laptop would still run off the brick.
