Was an extremely happy owner of MBP 16" A2141.[br]
2 Months ago became an owner of A2485. [br]
I do have the bad habit of not Shutting down the computers I just closed the old one and put it under my bed. [br]
As it's a great dust collector I decided to give it to my parents however for my big surprise it's not turning on.[br]
Initially I thought that the battery is drained so I left it connected to the genuine 96W charger overnight.[br]
On the morning I didn't have much luck as the A2141 still doesn't have any signs of life.[br]
I tried different cables and made sure that the charger is working (by connecting the new MBP) and different USB ports.[br]
[br]
So I started my investigation:
# Reset the SMC
# Reset the NVRAM
# Open the bottom of the MBP[br]
- clean the dust[br]
- check the batteries (look fine)[br]
- disconnect the battery[br]
- press and hold the power button for 10sec[br]
- connect the charger and press the power button
-
Unfortunately no luck. There wasn't a single movement of the fans, noice from the speakers or light from screen :-( [br]
[br]
From what I understand there should be a faulty Logic Board.[br]
The machine is out of warranty (that's why I did step #3 of the investigation).[br]
[br]
1.5years ago I spilled a bit of water on the MBP. Turned it off immediately and wasn't using it for 3 days. On day 4 it was working except the screen, however it wasn't an issue for me as I'm using external screen. For my biggest surprise the screen turned on 2 days later.[br]
Since then I never had any issues with the machine.
After opening it I noticed a tiny erosion (marked on the image) which I cleaned with alcohol

Ordered an USB C Power Meter Tester to check the power.[br]

Wanted to ask for some advice what I should look for as a possible reason for this faulty machine?
I'm pretty handy guy and finished an electronics schools (15 years ago and haven't practices much since then as I focused on Software) so more than happy to dig and try to fix it myself (happy owner of the ifixit pro tech toolkit).
