3115-B Water Damage, Green light, no Fan

[MaxFix]

Hi,

Corrosion around R1801, R1802, R1803, C1802. Replaced them and fixed broken lines between them but still doesnt turn on.

PPBUS_G3H 12.6V

PP3V42_G3H 3.48V

PP3V3_S5 3.3V

P3V3S5_ENTRIP 0.71V

PP3V3_S5 is 140 diode mode. Does that mean I have short to ground?

Thanks!

No short at all.Do you get 3V3_SUS?
Check all (4) RTC signals at page 16.

3V3_SUS - 0V

SYSCLK_CLK32K_RTC - 0.38V

RTC_RESET_L - totally corroded

pulled a wire from C1803 to R1803 and voila, its alive again!

Thanks for you help man. You helped me fix 2 motherboards today +100 to your karma!
