820-00840 with 13v on ppbus.
PP5V_S5 starts at 0.4v and then drops to 0v (no pulsing).
PP3V3_G3H = 3.4v
PP3V3_S4 = 1.1v
L7670 is pulsing and L7030 is stable 0.9v
820-02773 that boot loops to half loading OS, sometimes not even that. With battery disconnected the loops are seconds long.
Tried disconnecting everything. No change.
Tried booting in safe mode, it also shuts down on loading boot options.
Wont go into DFU mode.
Hi, got 820-02773 with tons of liquid damage, it was turning on after cleaning but not anymore.
PPDCIN_USBC_AON = 20v
PPBUS_AON = 12v
PP3V8_AON = 3.8v
PP5V_AON = 5v
PPVDD_AWAKE_PCPU = pulsing between 0.5 and 0.7v
U6360 is heating a lot.
AUD_3V3_S0 = 3.3v
L83_LDO_EN = 2.8v
PP1V8_AUDIO = 1.2v
PP1V8_AUDIO resistance to ground is 7.7 ohms with U6360 connected and 11 ohms disconnected. I replaced C6361 just in case.
Replaced U6360 2 times but still getting hot.
820-00850 no signs of damage, touchbar's touch function just stopped working (display works fine).
Tried 2 known working touchbars, no change.
PP1V8_DFR is 1.8v.
J5100 diode mode (dont have good board to compare but they seem good):
TP_DFR_TOUCH_PANEL_DETECT = 0l
DFR_TOUCH_LID_OPEN_L = 0l...
Sorry, i made a mistake, one of my probes was displaced and the multimeter was not reading correctly.
I do get 1v on the 1v1 ldo lines except on UB300 (the only port that has 20v).
Replaced UB300 but no change.
Diode mode on PP1V1_UPC_TA_LDO_BMC is still 0.450.
No history available.
Tested...
I replaced UB090 just in case, but no change.
Note: i did test each 1v1 line with its corresponding port connected. All other LDO lines have correct voltage.
