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

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

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

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.)

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?

Hi, I hope someone can throw some light on my problem. I recently repaired a laptop Presario 1200 (model 1215EA) (Broken screen). The battery had also come to the end of its life. I've purchased a new battery, however every time I try to charge it the battery LED pulses slowly six times, remains solid for about a minute (during which time the battery charges) then it just flashes until I remove the power supply and reinsert it. I've managed to charge the battery by removing & replacing the power supply, however, this took ages... I've updated the bios etc... Any suggestions??

Regards Andy
N.B. I've noticed that once it reaches 89/90% it keeps going and charges the battery fully (100%)...

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.

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!!!

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 have a Vaio VGN-NR120E, it's about 3 years old and it's been a while since the new battery started to die (it lasts about 15 minutes when working on just battery). I got a new battery just yesterday, and it was working OK, but when I went to plug the computer to the AC for charging, it reads "plugged in, not charging". I've been looking around the web and see a lot of people have the same problem, but their solutions haven't worked for me. I've tried uninstalling/installing the ACPI compliant control battery thing, shuting down my laptop and taking battery out/in in many different combos, but nothing's working.

When I put the old battery in (which still charges, but as I said only lasts about 15 minutes), it charges normally.

I have Windows Vista Home Premium.

Hi guys!
i recently purchased an used NC4400 laptop for work....

i chose that model because i have several years working with it and is one of the most rock solid laptops i ever have tried...

but this time i think the seller sold me a defective one...

the seller sold me this one without battery and without charger, its ok for the price (70bucks) i already have couple of those batteries around there and some chargers...

when i receive it, i plug it to the ac and after 20 minutes notice the laptop don?t charge the battery, i tried another battery and the same, i decide to try the battery in another nc4400 i have and it charge it fine.... so is not the battery, and is not the power adapter...

i checked the BIOS and it is exactly configured like the others nc4400 i have here.

what is wrong here?

Thanks in advance!

If I have it plugged in when it's off to try and charge it the Power LED is green and blinking and the Select Bay Battery LED is amber and blinking and no charging happens. I tried removing the primary battery to see if it was causing this and it still did the same thing...anyone know what causes this? It's a Tecra 8100, PIII 750, 512mb ram, Windows 2000 SP4. I checked the manual, it's says nothing about the power light flashing green and nothing about the battery light flashing amber. Thanks for anything guys.

My laptop seems to be completely out of charge, and the only way to use it is to plug it in. If it becomes unplugged, then it immediately shuts off. I am running Windows 8 Pro on a Samsung Series 9 Notebook (P900X3B). It is not a fresh installation of Windows, it was updated from Windows 7.
The battery indicator in Windows 8 states that the battery is at full charge, but it really isn't. I can't remove the battery because it is built into the laptop. Is there any way to fix this?
Thanks, HB

A:Laptop battery always at 100%, doesn't charge at all

Hi -
Samsung does make some sacrifices in order to keep the Series 9 so thin and light. The battery, memory, and solid state disk are not user replaceable.
They’re sealed up inside the laptop case, and while you might be able to remove some components and replace them by performing minor surgery on the notebook, you’ll probably void your warranty in the process.

A:how long should a charge last on a laptop battery?

I would drain the battery completely and then recharge it. The time between charges depends on the device and what you're doing. If you're doing stuff like video encoding or other cpu\gpu intensive things, the battery will get used up faster.

Your laptop isn't going to "charge" with out a battery installed, because there is no battery in it to charge. Do you mean, it doesn't power up without the battery installed but the power adapter attached? Then you may have a bad power supply and or DC adapter on the laptop.

You can likely take the battery to a service center to have it checked, or find someone with a laptop that uses the same battery to see if yours will charge. Of course, it never hurts to have an extra battery around.

Incidentally, I think it a good practice to somehow 'mark' those removable components to ensure that no monkey business has taken place with the servicer. Most are reputable, but as in all occupations, there are those who are willing to excercise immoral practices.

Hi, I'm new to the forum, sorry if this is posted in the wrong place.

I haven't used my laptop for a while as I'm home for the summer from University and have been using the home computer. I turned my laptop on for the first time in a couple of weeks today and for some reason I can't get it to charge.

The battery light is staying green all the time despite there being 0% battery available. The laptop (on Vista home premium) works fine when plugged in but as soon as I removed the cable or turn the plug off the laptop just goes off.

This hasn't happened before and I'm baffled. Can anyone help? Much appreciated,


A:Help needed - laptop battery will not charge

Sounds like the battery is dead and needs to be replaced. You say you haven't used it for a while so it's possible that the battery has completely discharged and may not be capable of recharging.

This is just my opinion as I have no knowledge of laptops or their batteries so if you want to wait for one of the experts to help feel free

I have an Alienware 14, and recently it refuses to charge past 45%. I'm aware it may be an issue with the battery, but the thing is that it used to do this a while back, with 53%. and then one day, it just fixed itself and i've been fine at 100% for months, until yesterday when it just went down to 45% (as i';m looking at it now, it says "46% available (plugged in, not charging) does anyone know what might be the reason? I've tried updating the BIOS, i've uninstalled and reinstalled the Compliant battery thing in device manager, and i'm still unsure what could be the issue here.

Are you using the 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.

Hi kannmoore and welcome to TSG.

It looks like there's a problem inside the laptop. To check try charging a known working battery overnight.

If the above doesn't work can you power the laptop directly without using the Docking Station ? If you can try that as well to see if it makes any difference.

Hi all,
I have recently purchased a D430 laptop that comes with Vista. I found that there is no way I can set the charging scheme (i.e. charge only when battery power falls to xx%, etc that I found in my old IBM one). I don't want it to cycle at high percentages as it would degrade the battery fast. Removing the battery is not a good solution - it seems this model is designed to have the battery attached all the time.
Any suggestions?

Symptoms: Dell Laptop (about 1 year old) only turns on when charger is plugged in. The second the charger is pulled out, the laptop shuts off. The laptop does not seem to charge as it doesn't even recognize a charger as being plugged in. I'd really hate to spend $150 for a new battery/installation already. It has been doing this for 1 day, since coming back from Vegas where I took the laptop with me.
Is there are fixes to this?

A:Solved: Does My Laptop Need a New Battery?? It doesn't seem to charge

Depending what type of battery, they can be pretty short-lived. If NiCad, they die fairly quickly if recharged when they are not completely dead. They need to be "cycled" and die before being recharged or they "remember" the point they are at when charged as being their new minimum and will not hold much charge.

Lithium batteries and NiMH should last a long time.

Check with Compaq for a battery calibration utility for your machine. It may be that simple. But if the battery still doesn't work right, it probably needs replacement. The chargers are almost never the problem.

Hi, I've had this Elitebook 8570w for about 3 months now, and have taken almost perfect care of it (and the battery), but the battery is acting up. This problem just started today. The battery charge shown isn't correct. It says it's, say, 70%, but shuts down because the battery is too low.  When I plug it in and turn in back on, it displays the correct percentage, but as soon as I unplug it the percentage starts showing incorrectly again. I've tried reinstalling the driver, but it hasn't fixed the problem. Right it says it's at 79% but I know it should only be at about 20-40%. Any help?

Hey everyone new to the forum, name is James.

So basicly my laptop battery stopped holding a charge and is not be read as connected.
This happened because I was working to fix a physical issue and had removed the battery and put it back in multiple times while my charge cord/ power core was connected.

Hense I can't use my laptop without it being plugged in anymore, so I was wondrring if this is fixable if so what would something like that run me?

A:Laptop battery charge, and connection question

The cost of a new battery will depend on what make & model laptop you have because the price varies by manufacture. First i would try cleaning the connectors between the battery & the laptop because some dirt may have gotten in there & could be interfering with the battery's operation.

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.

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."

Hi there .. Do you have Power4Gear Installed ... If so i would look into the Settings for that could be a power plan so save Battery life ... It should also be able to tell you your Battery's Health status ... I have no idea how good this Program is could be total crap ...

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.

How long have you been using the laptop with battery? Is it still under warranty?

Your battery has failed and must be replaced. They're only good for three or four years. Happens to all laptops.

I bought this computer an year ago in Septermber 2014, my device is out of warranty. Since past one month (a month after installing windows 10), my computer went all crazy. First, the fan starter brrrring, a constant noise and I have no idea how to deal with, its not the dust I checked that. And since a week and a half my screen started flickering on battery. At first if battery dropped below 25% the screen flickers and recently the batter percentage got bigger and bigger. Now, screen flickers at 90% battery. If I use chrome to watch youtube, the screen flickers even faster, I loosed up a lot of places online. No result. Please help!

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)???

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

When on battery my screen flickers to the point that the laptop is unusable.  No problems while it's plugged in.  This issue started under Windows 8, but only appeared when using heavy graphic applications like Photoshop.  Under Windows 10 it starts happening almost immediately when unplugging the power. I've tried changing the power options to ensure it's set to maximum performance while on battery, and tried both on and off for the adaptive display options with no improvement.  I've seen "replace the LCD panel" as a solution in another thread but that does not seem to be a logical fix given that the system works fine under power. Anyone have any other suggestions?  This seems to be a common problem, so I'm hoping there's a driver/update fix.  Has anyone tried getting a new battery?Thanks!!

Hello fellow techies,
I have a situation with my Compaq Evo N600c battery or something in that directions, so I need possible solutions. My laptop needs to be plugged in at all times, which makes it frustrating because its a portable laptop. If it becomes unplugged the laptop will turn off within 10 seconds flat. I fear that this will, if it hasnt already done so, mess up my electric circuits among other components. Can any of you suggest or recommend options I can use to diagnose the situation. I would like to find out what the problem is, whether I should buy a new battery or some component or prong that I need to replace? Thanks for the feed back!


A:Battery will not charge or hold charge?!?!

Yup, sounds like a battery problem.

First, make sure the battery has a charge. Most laptop batteries have a button on them somewhere you can push that will give you the power level. Alternativly, there should be a utility in windows or the BIOS that will allow you to check the power level.

If the battery has no charge and isn't charging, then replace it with a known good one and see if it will charge up when the laptop is plugged in.

If the good battery won't charge up, then there is a problem with your motherboard.

If the battery has charge but won't power the system, then there is a problem with your motherboard too.

If this is the case, then the best you can do is contact the laptop manufacturer and get them to replace the motherboard.

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!

I have an acer laptop and it has been working great for the past year but now my battery won't charge to 100%. This only happened recently and my laptop is plugged in for awhile but it'll only read to 80%, 2 weeks later; 53% and now its only 28%. The thing is.. my laptop IS charged. when i unplug it, I get my usually lifespan of the battery before i have to plug it in again to recharge and it only charges to x% again. I've tried "draining" my battery and letting it charge again but it won't charge to 100%. Is there anything I can do to make my laptop read my battery correctly again. Thanks so much!

*I should add its an Acer Aspire with a 6-cell Li-ion battery and this is the only problem I've had thus far with my laptop
