I have this MacBook on my bench with the following issue:
The MacBook works perfectly fine on battery power, but as soon as I connect the charger and put the machine under load (for example, running Cinebench), the MacBook reboots.
I replaced Q5240 and U5200, and now the MacBook reboots under load—whether running on battery or the power adapter.
PPBUS_AON_REG=12.7V
PPDCIN_AON = 19.78 V (with adapter connected)
PP3V8_AON=3.8V
PP5V_S2_MAIN=5.15V
