Hi,
I received this board. It was liquid damaged
I don't know where exactly, because it was cleaned before I received it.
Corrosion:
Around LVDS
KB backlight connector
J6100 - I removed it
U7200 - some corrosion next to it.
I cleaned the board.
The board goes to S0 state, but CPU Vcore does not present.
Missing CPU_VR_EN.
PPVMEMIO_S0_CPU 1.205V
PP1V05_S0 is present.
ALL_SYS_PWRGD - 3.3V
Y1905 - oscillates
L7630 - 1.05V
PCH slowly gets warm
U7200 powers on as far there are PP5V_S0 and PPVIN_S0_CPUVR_VIN.
Should I just change U7200 or is there something I'm missing?
Thank you.
