Windows 7: Laptop battery problem: laptop powers off unexpectedly at 20%

Laptop battery problem: laptop powers off unexpectedly at 20% left

Hello there,

I have an one year-old ASUS K53S Laptop, Windows 7 Home Premium, 6GB Ram and 500HDD.

At the beginning, my battery lasted >3 hours in Balanced power mode (which is the one I alway use) and now due to regular use it last about 2 hours.

Everything normal until here. About 2 months ago, i started playing this game in full screen with the battery on and it last about 30-40 minutes until it reached the low battery warning (11% left). I would then plug the power on and resume the game, charging the battery as well.

After a few weeks, the warning stopped appearing in the desktop and the computer automatically hibernated (5% left) with the game still on. So i plugged the ac power on and resumed the game right away.

This kept happening from that moment on: every time i played the game it would reach 5% battery left and hibernate for itself, whereas it should appear the low battery warning at 11% left where I would plug in the ac power and charge the battery without going into hibernation.

On top of that, my sister kept stealing my ac charger for charging her Toshiba Satellite as she often forgets her own charger at her workplace!

Now, at the present day, when the battery reaches about 15-20% left, the laptop power off unexpectedly, as if I had pull the battery off of the laptop.

It must be from all those time it would reach 5% left, with the game still on, that "tired" the battery and now it won't even last further than 20% left...

It might be a problem with the battery or the ac charger that my sister used in another computer.

Both the battery and its respectively ac charger are the ones that came with the laptop.


Regards,

I can't help you with your sister. It is my experience that sisters are built that way on purpose.

If the battery is three years old, then I'd suggest replacing it.

If you have a local store where you can get the laptop properly cleaned, that would also be a good idea.
