i spilled lemonade on my laptop last year and i got the motherboard and the keyboard replaced on my laptop and ever since that the backlight doesn't work. but about 3 months ago one day it randomly springed back to life, until i restarted my laptop... It doesn't light up when i boot my laptop. i have done everything possible to get it working but it isn't. any ideas? i have updated UEFI to 208, newest atk packages and all newest drivers for everything
