So it happened about 2 weeks ago, I updated my BIOS version from 1.08 to 1.10 and soon realized that the laptop is not running on battery. It's running directly on the power supply. When I turn off the power supply the laptop goes off immediately.
1. I tried resetting the battery it didn't work
2. Battery indicator always on blue not showing yellow anymore.

  • Try this:
    a) enter the bios and then press f9 and then f10;
    b) then, turn off the notebook and press the power for 30 seconds.
