Windows 7 Or Laptop Is Not Reading Battery Correctly?
Jul 26, 2010
just started cropping up about 2 days ago. For some reason, when I use my laptop on battery, the screen will go completely dark after about a minute of use. This most recently happened this morning. The first time this happened, I just held down my power button, and then turned the laptop on after a minute's wait. On that occasion, the laptop started up again, and it seemed to be waking up from hibernate or something.
But this morning, when I held down the power button and tried to turn it on again, it wouldn't. I plugged in my charger, and then the laptop was able to resume Windows, but the weirdest thing is, it said my battery was at 0%. The reason that seems odd to me is because it was fully charged last night. Right before the random screen turnoff, I checked my battery status, and it said 94%. So why did it go down to 0% after a minute and a half of use?
Now that my laptop is on, and connected to the charger, it is fully charged after about 10 minutes. Is it Windows 7? Or is it my laptop? The laptop will be 3 years old this November. Working on battery hasn't been a problem except for these past few days, and I haven't installed any new programs, or altered any settings that I'm aware of.

I have a brand new battery in an Acer travelmate 5720. It has a BRAND NEW battery in it. at 50% power, the laptop dies as if the battery is totally drained. Will not even post to bios. Just dead.I adjusted the settings for the battery in windows to alert and shut down the computer at 50% to save whataver data is there, but this is not a good fix. There are no settings in the bios for adjusting the battery. What is going on in windows to cause this?I've read thru the threads and saw a lot of people with this problem only to be told that it's their battery or the laptop, and blah blah blah. Anything but Windows 7.

I have an ASUS K50IE laptop that i had for 2 years now. been working fine until 2 days ago.this problem has been bugging me for the last 2 days. here's why.my laptop suddenly didn't detect my battery. thought it was because my battery was dead. I searched the net on things to do before "throwing in the towel" on my battery and today i came across a blog where the instruction was to uninstall the Microsoft ACPI compliant control method battery driver. I did just that and my battery suddenly worked! well sort of. now here's where it gets all weird.every time i open my laptop i do the following:1. plug in AC to laptop.. turn on laptop.3. unplug AC.3. laptop runs on battery.4. log on to windows.5. battery icon shows up as an empty charging icon then shows the "Battery is not detected" icon again.please take note that my laptop is still ON and WORKING. so this means (MAYBE?) that my battery is working.

I am having a problem with my Acer aspire s3 ultrabook (i7 2637 4GB ram running windows 7 home premium 64 bit).The fan is on all the time, really loud and noisy, and the laptop is usually heating up too rapidly, and the battery life is less than 1 hour on power saving mode!! I don't know how it became this way, but I think that I once downloaded the windows 8 preview, installed it, but nothing happened, and I could not detect it on the control panel or in my hard-drive, it just disappeared, and my laptop has not been well eversince. I am not sure If I want to restore it or if I have a restoration point before the problem, but I have important software I do not want to lose.

Ive got a Packard Bell laptop but have just noticed that it only starts up intermittently.Mostly I just get 'Windows is starting' and thats it - just a black screen. I have to shut it down and then it starts up in safe mode repairing the incorrect shut down i imagine.

Well I just had the first bsod from my laptop and after the reboot it got stuck -> reboot and select a proper boot drive.I checked the bios and my hard drive was still being recognized. After it I turned the laptop off I took the battery out and I turned on the laptop. The laptop would run normally. Then I ran safe mode and it worked fine and normal mode too. So I'm wondering if it's something wrong with my laptop battery or just really bad luck. I still need to run it again with the battery.

I have a new HP Compaq laptop and the battery meter is in % which really doesn't tell me much. So I am looking for a battery meter that tells me how much time I have on battery power. I have looked at a few sidebar gadgets and couldn't find anything and Google really isn't helping me either so I thought I would ask here after 2 weeks of research and coming up empty like my battery.

I have a Toshiba L645-S4102 laptop. It is a dual core with 4 gig of ram running Windows 7.When I am running on AC power it is very "responsive" when I am on the internet going from web page to web page. When I am on battery it is sluggish and not near as responsive.Is the the way it is supposed to work or is the some setting in "power management" that I need to change?

I have a HP G71 with windows 7 64bit and its really annoying when I get to 13% battery it says low battery and when it gets to 8% it just shuts down... i was wondering if there was a way to disable that function or if there was a way to completly eliminate this function. Ive searched all the battery settings and have searched the internet and sadly cannot find anything about how to get rid of it.

I haven't verified this yet, but I wondered if it's a possible bug?
I bought a Dell XPS M1330 over a year ago and it came preloaded with Vista Home Premium. Since I want to keep the batteries in good condition I run the laptop with no battery connected and AC plugged in whenever it sits on my desk at home.
However, in Windows 7 it seems that Windows wants to put the laptop to sleep after 10-15 minutes if I do this. Since I have various USB devices plugged in, especially external storage, this is a problem. It goes away if I run with the battery plugged in but like I said, not verified yet.

We have an ASUS K52Jr purchased in April last year. At the start of this year the hard drive packed it in while I was trying to download something on ITunes and it would not start up again. We were moving and so didn't get around to taking it in for a couple of months. Anyway, a couple of weeks ago we went it in to ASUS and the hard drive was replaced under warranty (2-year warranty).The laptop is working fine now on AC power but the battery will not charge. I've tried shutting it down, taking the battery out, restarting it and putting the battery in while it's on, but no dice. I've also tried uninstalling and reinstalling the power management driver from "Device Manager". It was saying "plugged in, charging" on the battery icon but the "power bar" on the icon would stop moving within a few seconds of putting the battery back in and the power level would stay at 0%. Yesterday it started saying "plugged in, not charging".Is this because the battery was left in the laptop while it wasn't working? Is it just coincidental that the problem started after the hard drive was replaced?

The following text is the culmination of information from a failed attempt to get qualified advice via the Yahoo Answers route. This is why the text is not in a strictly narrative form. I thought it best to provide the accumulated data as is:I recently purchased a replacement battery for my Acer laptop (Acer Aspire 7740-5029). The battery is not a "manufacturer" replacement battery, but is of third-party manufacture.When I turn on my laptop (windows 7 HP 64bit), the laptop does not recognize that the [new] battery is inserted, even though the new battery is inserted. The laptop does function with the replacement battery, but it does not report to Windows the remaining charge, or even that the battery is even there. So, this being the case, I have no idea of the charge/time remaining as I use the laptop and is of no use to me because of that fact.
Technical information: *The factory battery (OEM) is a Sanyo AS07B31 (lithium Ion, 4400mAh, 48Wh, 10.8V, 6 cell). *The replacement battery is a Famis FAM18674 (Lithium Ion, 5200mAh, 49Wh, 14.8V, 8 cell)
Additional Details:For anyone who advises that I seek out and download/update drivers for the new battery, I cannot "download the driver", since in the Device Manager does not even recognize the new battery as being there as an unknown device or otherwise. I cannot update or install a driver for device that Windows doesn't know is even there.
Additional Details:One other person has submitted that the original battery that came withthe laptop contained DRM electronics, so that one cannot replace the OEM battery with a non OEM model.
Additional Details The battery status/plugged-in status icon is on the taskbar and is not hidden. I have always had my taskbar set up to show all icons and to hide none of them. With the laptop not plugged into the AC and the new battery in place, the only icon that is showing is the "no battery detected" icon. Even though the laptop is drawing power from the battery, Windows does not "see" that there is a battery and therefore cannot provide battery usage/time remaining, etc.

Some time ago I bought a battery for my laptop (Asus G51JX) and, it didn't work, I've sent it back and bought a new one with the same specifications (11,1V, 7200 mAh, 9 Cells).Now, when I start the computer on AC only, it works fine, but when I put the battery, the little icon on the taskbar goes up and down and then stops, If I remove the power cord, the laptop continues on but for my surprise it says "Plugged in, Charging" WITHOUT the power cord!, how is that possible? it is not from the OS because I tried another HDD with a completely different installation and it did the same, now my question is... Is it BIOS or the Motherboard?

My Dell M11x laptop battery had very little life left and would only run for about 20 minutes when unplugged from the adaptor. I purchased a new M11x battery, but seeing as I usually use my laptop plugged into the adaptor, should I save this new battery for periods when I know I won't be able to be plugged in?

Occasionally my Laptop (Windows 7, 3gb RAM, Compaq Presario CCQ61) doesn't boot up correctly. As in normally the problem is ''Windows cannot find an OS'' thats not the exact wording but somewhere along the lines, its a blue screen and there is also some other writing underneath. I tap the off button to turn off and then i turn on again, sometimes it boots up fine and works good but sometime like it says run system repair (reccomended) so you do and it go's through steps and tells you to do a system restore which I do then it does work...but then maybe a week later you will open the lid and it won't respond (the mouse won't move and you have to hold the power button the turn it off., its starting to get annoying at this stage, considering restoring to factory settings.

My Gateway laptop MD-8718u will not recognize a new battery. It had been updated to Windows 7 and because of that update much of the
MD-8718u
software (like the camera) became out of date. I went into the BIOS setting and enabled the "recognize battery" command and upon turn-on it automatically becomes disabled. Gateway has a BIOS update for Windows 7. When I tried to install it, I received a "BIOS Unflashable" message or something like that. Being a integrated motherboard, the BIOS is probably soldered to it and difficult to replace. Can anyone tell me how to get my system to accept the new battery?

I'm having problems when my laptop goes to sleep, I'm not sure what happens but when my battery is low, it goes to sleep but doesn't wake up even if I plug the charger in. The only way I can get this fix is to restart it by shutting it down through the power button.

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.

Okay, so it's been over a year, and my 6cell battery is beginning to die out. I ordered a replacement battery from eBay rather than Dell. I'm a college student, and paying $50 sounded better than paying $200. Anyways, I bought a 9cell battery for my XPS. So here's what happens when I plug in the new battery:
AC Charger with NO battery: Computer runs perfectly fine
AC Charger with battery: Computer runs perfectly fine
Battery with NO AC charger: Problems...
When I plugged in just the battery alone, I went into BIOS and saw that the system's date and time were screwed up; it was showing some weird date in the year 1901. With this new battery, sometimes the hard drive wouldn't load. For example, when I turn my computer on, I can hear the hard drive spinning, but after a couple of seconds, the whole system just...freezes.
I initially thought it was a problem with my hard drive, since a screen kept coming up saying that some of the Windows files were corrupt. I did a clean install of Windows 7, and even tried Vista, but still nothing. With Vista, the date and time would still mess up, and sometimes nothing would load. I even tried system restoring after booting from the CD drive, but I received an error message that I had no shadow copies to restore from. I tried starting up with another hard drive, but still had the same issues.
Right now I'm using my old battery, and I get the message "Consider Replacing Your Battery." Can anyone help shed some light on this issue? Does the problem seem to be with the new battery?

My laptop dies if I am on the battery and the battery percent gets between 25-40% then it will just completely shut off. It never used to do this for the first 8 months i've owned it. Now it does it every time I'm on the battery. Also, right before this started happening I was getting GREAT battery life out of my battery, so I don't personally think the battery has gone bad, however you may feel different!

When my laptops battery reaches critical it will usually hibernate as all of them do. When it's switched back on it'll give you the option to do a system resume. The past 3 times it hasn't though, it has brought up the black screen saying windows didn't shut down properly, and giving me the options to start in safe mode etc.
