check the power supply voltage at the moment of awakening
3.38V on the cable with screen detached
3.23V with screen
too low?
402WP checked it is not damaged
2x N10, KJH, K77, 402WP replaced, no change
B1, B2, B3 are inductors so no short there
There are i7512, i7822, i7975, one more KJH, 2x K1N, MJ8A, RT9193, 2x memory chips and main wiseview chip that i didn't replace. Also 3x very small chips i couldn't even identify they marked KJGW4.
Somewhere i read those ixxxx chips are to reduce flickering. When entire machine wakes from suspend there is very noticeable flickering on the bottom of screen (but not every time)
To get 7975?
