The problem with my laptop backlit keyboard is, it's led glows during boot up and also remain responsive to F8 toggle (on/off) for a while but after few second it dies and doesn't turn on, no matter what.
So far I've tried re-installing a fresh OS(win10) and updated all the drivers too.
I've also tried updating the BIOS to it's latest version.
 
Model no:

    Hi Rowzun,

    Try to do power drain,

    1. Shutdown the unit.
    2. Unplug the cables connected to the unit.
    3. At bottom of the unit there will be a small tiny pin hole with a battery symbol close to it. Take a pin or a paper clip insert into it you feels like pressing a button hold it for 20-30 seconds.
