Hi team,
PPBUS_G3H: 8.59V
PP3V42: 3.401V
PPRTC_G3H: 3.310V
PP5V_S5: 4.994V
PP3V_S5: 3.310V
S4 State pulsing
SMC_ADAPTER_EN : 3.366V
PM_BATLOW_L : 3.305V
PM_DSW_PWRGD: 3.398V
SMC_PM_G2_EN: 3.396V
Checked all SPI Bus Series Termination traces and resistors
Put flux and heated SMC and SPI
Re programmed U6100 with medusa: NOK
Replaced U6100 and re programmed (Cleaned Pram, ME, SN Crc ): Not Ok
Still quarter Fan Spin
Sometimes When the medusa is connected fan starts running normally.
Re programmed with 00165 Dump bios just for try : Board Starts but no Chime, No backlight and No display.
Back to 3437B bios and pulsing state
Maybe not SPI finally
