Recently I turned my backlight off on my keyboard using fn+f9 . After turning the backlight off, the keyboard stopped working. The keyboard is fully function during BIOS and before boot occurs. I have tested this in GRUB , also I can go to boot options/menu using keyboard before boot.
The Problem is persistent in both ubuntu and windows.
Does anyone know what might be the problem or is there any way I can turn the backlight on using software as I can't use my keyboard hotkeys.

  • Hi,
    Do you have a battery reset pinhole at the bottom? Could you please post the full model name, like PH317-xx, if you have the reset pinhole, follow the instructions in the video, once completed leave the laptop to rest for a while before reconnecting the AC adapter and start using.
    If you don't have the pinhole, disconnect from mains, press the power button for 15 secs, leave the laptop to rest for a while, then try starting again to use.

    The model name is PH315-51.
    The solution didn't work. I tried all of them.

    The bios version is 1.26. No it occurs both when it is plugged and when it is unplugged. 
  • What was the factory installed bios version? Have you tried to disable this function and check if the problem still occurs?
