    Hello,

    Today, after some heavy usage, my Acer Aspire 7720 laptop started to accept only ~92% of battery charge and never gets out of that.

    Also, the battery LED flashes inconsistently (e.g. will stay on for a few minutes, then will blink wildly). I

    Any ideas? I use Arch Linux as my main OS, but it seems to be platform-independent (even when it's turned off it happens). The BIOS is the latest 1.45.

    Thanks!

    I've had similar problems, but they were solved by disconnecting the laptop from power supply and removing the battery and putting it back after few minutes.

    You could also try to reset the BIOS. After removing the battery, press the power button and keep it pressed for 20 seconds and then plug the power cord in. Maybe it will help.

    Indeed, I did this then left the laptop to charge overnight. Now it is working correctly.

    Thanks.
