Hi All,
This backlight problem has got me stumped.
No liquid spillage, that I can determine.
The laptop works fine, except no backlight until the laptop boots to the login screen.
SMC_LID = 3.4V
I replaced the backlight driver as i was out of iddeas. All resistors measure correct values around u9000.
Backlight enable is 3.3V from the get go. Makes no sense.
Any clues
