The MBP is dead after battery drain
Hello!
Was an extremely happy owner of MBP 16" A2141.
2 Months ago became an owner of A2485.
I do have the bad habit of not Shutting down the computers I just closed the old one and put it under my bed.
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.
Initially I thought that the battery is drained so I left it connected to the genuine 96W charger overnight.
On the morning I didn't have much luck as the A2141 still doesn't have any signs of life.
I tried different cables and made sure that the charger is working (by connecting the new MBP) and different USB ports.
So I started my investigation:
- Reset the SMC
- Reset the NVRAM
- Open the bottom of the MBP
- clean the dust
- check the batteries (look fine)
- disconnect the battery
- press and hold the power button for 10sec
- 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 :-(
From what I understand there should be a faulty Logic Board.
The machine is out of warranty (that's why I did step #3 of the investigation).
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.
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.
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).

Hey Handy Pol!
I'm having the SAME issue as you now! I have the A2141 and I put that in sleep mode and went on vacation for a month... Came back and I pressed the power button and I was in MacOS... But then I noticed I had 2% battery life so I quickly grabbed the USB-C cable and charged it... The battery icon didn't have a charger so it wasn't charging at all.. I figured, maybe a reboot might help.. So I rebooted.. At this time, the battery had depleted and it showed the 'low battery' icon with the lightning bolt... After that, I was never able to turn it on again...
I brought it out to the Apple store and they plugged it into configurator... It detected the computer but eventually timed out... The reason I got from them is a 'faulty' logic board... Somehow I'm not convinced...
I have tried all your troubleshoot steps except for number 3... I've changed new charger and USB-C cables... Tried another wall outlet... No luck...
Have you discovered or fixed the issue yet? I just ordered a new battery replacement but I haven't opened up the computer yet...
