[SOLVED]820-2838 not turning on green light on charger no fan spin missing P3V3S3_EN

820-2838 not turning on, has green light on charger (just noticed stays green ??) no fan spin missing P3V3S3_EN (no short to ground) at q7903 which if im right comes from PM_SLP_S4_L , i dont seam to have any of the power rails from PM_SLP_S4_L (S3 rails) , mmm now im confused or am i just going to lose with this one as that seams to come from the cpu , board had minor liquid spill but does have signs of being worked on before

Green light staying green is normal on these antiques. Also you need to manually power them on by shorting the power pads on SMC_ONOFF. If there is still no power check voltage on both pins of Y2810.

Hi Duke on pin 1 (RTC_CLK32K_XTALIN) i get 1.6v and on pin 2 (RTC_CLK32K_XTALOUT) i get 1.75v

now i feel stupid - shorting the pads turns it on , thanks duke i will be sure to remember that one
