Hi ,
on a2780 -820-02652 - macbook pro m2
laptops stuck 5V-0.16A
my measurement :
PPBUS_AON 12V
PP3V8_AON 3.8v
PP3V8_AON_MPMU 3.8
PP1V8_AON 1.8
PP1V2_AON 1.3
PP3V3_AON 1.5 not stable
PP3V2_S2 1.5 not stable
PP3V3_AON resistance to Gnd 60ohms
I injected 3.3 on PP3V3_AON and consumption was 120mA
PMU (U8100) deliver PP3V3_AON ?
If you have an idea..... -
macbook pro 16" m2 pro- A2780 - 820-02890 stuck at 5v - 0A on all usb port and magsafe.
all voltage:
PPBUS_AON = 0V , diode : 0,4
PP3V3_AON = 0V
PPVIN_P3V8AON 0V
PPDCIN_AON_CHGR = 5V
PPVBAT_AON_CHGR_REG = 0V
so U5200 not do the job
on u5200 :
PP5V_CHGR_SW = 4.5 v
CHRG_GATE_Q1 = 0V
1V8_SDA = 0V
1V8_SDC = 0V
i check u5200 diode on PHASE and LX pin -> 0.4
i don't understand something ,
sda and scl in u5200 are pulup by 1V8_S2 ( 0V)
so can not communicate .
1V8_S2 are...09-03-2025, 07:11 AM -

I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...06-27-2025, 08:54 AM
