    Hello, Thanks for looking up . My model is AN515-54. The dimming works rarely and stops working immediately again.

    Hello, Thanks for looking up . My model is AN515-54. The dimming works rarely and stops working immediately again. It doesnt even turn off after 30 secs.

    Hi,
    Use Fn+F9 buttons to decrease the keyboard backlight, use Fn+10 to increase the backlight, you can also enable switching off the backlight after 30 secs in NitroSense settings.

     I ve tried that 1000 times. I've owned this laptop for 8 months, never encountered this issue until today morning. I can't dim my backlit or turn it off!!! Though i can use fn to reduce screen brightness and volume control.

    OK, give this a try, switch off the laptop, disconnect from mains, press Power button for 30secs, leave the laptop to rest 15Mins, reconnect the AC adapter and fully charge the battery before start using, this battery reset may or may not rectify any glitches.

    Disassemble the laptop, disconnect the lithium battery and disconnect the jbl1 connectors:
