HP Omen15 dc0001nh keyboard light problem

[Tom_x]

Hi

I have this HP laptop, board: DA0G3DMBCE0 rev:E

The keyboard light only work, when i connect ac power supply(without battery), until the screen come with cmos checksum error. After this point light can't switch on. The first 5-6 seconds i can switch on/off light with FN+F4. When booing on, i can't switch on.
Keyb light controller Y59116, i think working, because receive i2c commands the firsr 5 seconds
I know schematic doesn't exist for this board
Someone know similar board, that use this rgb keyboard light controller?

regards
Tom

A Checksum error means something wrong with the BIOS. Try to backup your BIOS file, then flash another one.

A Checksum error means something wrong with the BIOS. Try to backup your BIOS file, then flash another one.

Cmos cheksum error means, when you remove cmos battery and cmos resetted/cleared. Bios is good.
