hi everyone.
i got that board from customer. he said liquid spill.
i have 12.54V so smc is working
PP3V3_S5 is 3.3V
PP5V_S5 is 5.0V
PP5V_S3 is 0V
PM_SLP_S4_L I get spices of 3.43V every about 3sec.
I found corrosion aroud U8330 but i think thats is not important now
next spot is around U 1900, but PPVRTC_G3_OUT is nice 3.42V and
PCH_CLK32K_RTCX! is a nice signal ,
that should be so because i have spikes on PM_SLP_S4_L, means the RTC is working
around u8005 is not like it should look.
i measured y1915, the 24Mhz signal is coming but frequently like the spikes from PM_SLP_S4
where to start here for the best?
