    HP Omen15 dc0001nh keyboard light problem

    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.

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

              Dell 15R-5521 keyboard problem (KBC?)
              by SDNarcia
              Hello, I have a Dell 15R-5521, with the problem that the Ctrl, Alt, Shitf and Num Lock keys do not work, I tested the keyboard with a keyboard tester and it is functional, I also got another new keyboard and the computer has the same problem with the same keys. Check continuity between the ZIF connector from the keyboard to the KBC and all pins are correct. I cleaned the ZIF connector and the KBC and I still have the same problem. I reinstalled windows just in case, and it didn't work. I updated the BIOS to the latest version A16 and there were no changes.

              As additional information,...

              When I hold power button for ~30 seconds or unplug RTC battery keyboard will work only one time. After laptop reset or shutdown, keyboard won't work.
