Hi everybody
trying to get data out of my MacBook Pro which I accidentally liquid damaged.
A Small drop of tea travelled on the back of the board nearby the trackpad connector: blowing it (see picture) digging a small hole in the motherboard (probably removed the first two layers.

Cleaned everything
Now trying to get this machine to boot again
Reading up a few post I've done some tests
Removed battery
A few measurements
- PPDCIN_G3H (19.95 V)
- PPBUS_G3H @ F7000, pin # 2 ( 0.13 V) (resistance to ground = 14 ohm)
- PP3V3_G3H (3.390 V)
- PPVIN_G3H_P3V3G3H (19.59 V)
- PPBUS_G3H @ D6902, pin # 1 (Missing, value 0.13 V)
- PPDCIN_G3H_CHGR @ D6902, pin # 2 (19.85 V)
- PPVBAT_G3H_CHGR_REG @ F7000, pin # 1 ( 0.13 V)
- SMBUS_SMC_5_G3_SDA (3.25V)
- TBA_VDDP (5 Volt)
- PPBUS_HS_CPU (0.13 v)
-L9400 both pin 11.05 K Resistance to ground
-Q7030 is getting 19.85 volt on pin 1-2-3
-Q7040 is getting 0.13 v on pin 1-2-3
-No voltage on L3500 and L8410
-0.13 volt measuring Q7030, L7030
couldn't find anything misplaced
how do I find if something is heating up without a thermocamera ?
Plugging in the USB C tester measures 19.99 volts and draws 0.067 amps
What should I test next ?
