Backlight on Dell G15 Laptop not working
Hi, I've followed the instructions posted on the Dell website and on help forums, saying to go to BIOS settings and enabling bright keyboard backlighting.
Unfortunately, my keyboard backlight still isn't working. It did once light up when starting the laptop from shutdown, but the light just turned back of again and wouldn't turn on.
This started soon after I signed out (rather than locking my pc) and signed back in for the first time in years. Doubt that's the cause, but just in case
No Events found!

Check the connection between the keyboard and mainboard. This will require disassembly. If you need a link to the service manual, post the full model number (i.e., G15 5579 etc).

@ejn63 I'm not competent with the practical side of computer hardware so I'll likely need to get it serviced. Are you sure I need to check the cable? It lit up fine like it usually does during boot, it just won't turn via any key press
