If that happens it means your hardware is bad. Not Windows.
Talk to the manufacture of your laptop, Not Microsoft.

LogicEarth, you're nonsense is about to be shattered.

Windows 7 is misreading the battery due to a bug in ACPI which results in the current battery level to be read higher then it is at for god knows what reason. i have proven this just last night by taking a completely brand new battery, which was shown by external tools to be under 10% charged and installing it into a running system.

Windows reported the battery to be 62% charged immediately, and proceeded to charge up to 100%. Every tool including windows at this point displayed the battery at having a charge of 47780, out of a possible 48840.

Continuing with the Battery break in the laptop was used till it entered hibernation. upon resume the previous charge statistics were infact 33300mVh and NOT 47780. This issue has resulted in ACPI stopping the charging at 70% of the full charge, resulting in the battery eeprom to consider the uncharged 30% to be marked bad due to cell decay.

Modification of the battery's eeprom (you need special tools) and testing with windows XP and Vista multiple times showed the first charge to only have a decay of 3%, compared to the first charge of 7, which was 30%.

I'll take it as complete ignorance on your behalf if you continue to post your in this thread at the expense of people who legitimately have a problem caused by Windows 7's ACPI bug on a wide range of laptops produced between 2006 and 2009.

I am sorry, but your nonsense needs to end. Windows does not control the battery. The HARDWARE controls the battery at all levels. Windows does not charge the battery nor is it in control of telling the battery when to charge. If the hardware tells Windows the battery is charging then the battery must be charging. All of the readings come from the battery, if the information is not accurate then the hardware is not giving accurate information.

Let me break it down for you. you have a HARDWARE problem. Plain and simple.
Recap, Windows does not control the battery or its functions. It has read-only access.

Those people who have problems with batteries on there computer need to STOP chasing ghost and talk to the manufactures of their computer. You are not helping one bit, yet you have the gull to call me out?! How hypocritical of you.

Either way, those at Microsoft have already taken the time to examine this in detail.
I'll take their word over yours any day.

This information is read-only and there is no way for Windows 7 or any other OS to write, set or configure battery status information. In fact all of the battery actions of charging and discharging are completely controlled by the battery hardware. Windows only reports the battery information it reads from the system firmware

Alright people I may have a solution, and it is quite simple.
Let me break it down to you guys.

When this message appears, and you know your battery is still good, it means that the chip recording your battery life is confused.

This problem is found in many newer devices on the market today. I call the problem "Selective Battery Amnesia."
SBA occurs when someone over exposes a battery to over-charging and commencing charging before the battery is truly low.

The fix though is simple:

(Read ahead of time or keep this up on a different computer while doing this so you don't get lost)

Put your laptop on to high performance, go into the advanced power settings, click battery, then change the critical power percentage to 1%.

Go to critical battery action and set to "Shut Down."

Now be patient and let your battery drain down (I suggest a hobby around the house while you wait).

Here's the interesting part, if you watch your battery level as it reaches below 10% it will stay there a for a while, this is where the origin of your problem is.

The chip says "HEY! I'M LOW, CHARGE ME!" In reality it isn't as low as it thinks, after a while it will go down a few more percent and eventually it will shut itself off.

Now try to turn it back on once (about 10-30 seconds after) it has been off.

If it doesn't turn back on it is drained, which is good.

Now plug it back in and turn it on. When you log into Windows, the "change battery" logo should no longer be there.

If this doesn't fix your problem, try other sources such as an incompatibility with your motherboard.

I hope this helps you all, I just did it to my computer and it worked wonderfully!

Listen to this guy.
I did exactly what he said and it worked.

Plus, this is what i observed.
I kept my Acer Aspire to drain it's battery.
At 7%, my laptop switched off.

I switched it on again and i kept it as it is to further empty the battery.

At 6%, i thought it's only matter of few mins, that it will completely drain away.
However it took 45mins to drain away.

Now you can see that i am not technically sound but i think batteries/hardware sometimes doesn't measure the battery energy properly.
While there was energy for another 45min, it still showed 6%; so basically let your battery drain down completely every once a while.

Hey peole this is NOT truly Windows problem, because i had windows 7 for nine months, and this problem wasnt here. Today, i got it. This is VIRUS that makes your system be unable to recognise how much % power is left in your baterry. After 1 hour my computer has switched OFF. I had turned it ON again and its working for more then a half hour, it is working at the moment with 0%, and i dont know how much more will it last... maybe half of hour more. So dont worry, you dont need to give 100$ for new battery, that one works good too.
