Liquid damage that was cleaned by somebody else.
When power on fan spins - then stops - then spins again and slowly ramps up and keep on spinning
On first fan spin there is 3.2V on pin 5 (SPI_MOSI) and 6 (SPI_CLK) for 2-3 seconds but then drops and does not come back on along with the next fan spin
SPI termination resistors and traces are fine. Replaced U6100 (still have the original) but no dice
5V_S0 = 5.1V
3V3_S0 = 3.3V
1V05 = 1.05V
1V35 = 1.35V
PPVCC = 1.7V
PPVRTC = 3.3V
PCH_CLK32 = 32KHz
Any clues ?
