Hi, 820-00687-A died when closing bottom cover after successful repair (hall sensor on keyboard).
First it had 20v 0a only on one side of usb-c. After replacing U3100 (from ssd dead board CD3215C00 same markings) got 20v 0a on both sides of the cable.
Power rails:
8.69v PPBUS_G3H
20.06v PPVIN_G3H_P3V3G3H
8.7v PPBUS_S5_HS_COMPUTING_ISNS
20.06v PPVBUS_LIO
20.4v PPDCIN_G3H
3.31v PP3V3_G3H
3.31v PP3V3R3V0_AON
5.06v PP5V_G3H
PP5v_S5 = 5.0v
PP3v3_S5 = 3.32v
PP3v3_SUS = 0v
PPVCORE_SUS_PCH = 0v
PPVCORE_S0_CPU_PH1 & PH2 0.00v
PM_SLP_S4_L = 0v
What also found (before, without and after CD3215C00 replacement):
USB_EXTA_P/N - SHORTED TO GRUND
Does this means that PCH is dead? Tested with 3 different dc cables, 2 chargers, 3 cables.
Thanks in advance.
