3 Keyboard and Trackpad not working, very slow and fans on full blast
Logic Board front:
Logic Board rear:
I have a MacBook Pro 13 Touchbar A1706 EMC3163, mid 2017 model with a number of (probably liquid spill related) issues:
It started booting very slowly and as soon as the OS boots up, the fans are running at full speed and the MacBook is very slow, almost unresponsive. (Safe mode to protect the system???) One by one the keyboard and later the trackpad died.
PRAM and SMC reset are no longer possible (because of the broken keyboard). I did, however, drain the battery completely, which should work as an SMC reset (and didn't help).
When booting in diagnostic mode, it shows a problem with the System Management Controller (code: PFM006) and a problem with the Power Management System (code: PPN001).
I would like to fix it by buying a donor Macbook, and I hope to fix my Macbook by replacing the logic board and probably the keyboard and trackpad. Since I'm not familiar with Apple products, I'd like to get feedback on whether this is doable (if there are any particular challenges) and whether my assessment that the logic board is defective is correct.
I greatly appreciate your comments and help,
Thanks,
Felix
Additional information:
The battery works fine and powers the computer for several hours,
the currently installed operating system is Monterey

Hi
At the moment it’s sounding like it could be spill related as you have already said
Let’s try and confirm this,if you could open the MacBook apart using this guide

@fritzpeppone - even before you open the system how about running the onboard diagnostics to see if an error pops. Restart your system and press the D key to enter.
Reference: Mac startup key combinations

@danj That's exactly what I did and described above:
"When booting in diagnostic mode, it shows a problem with the System Management Controller (code: PFM006) and a problem with the Power Management System (code: PPN001)."

@hellomacos I just opened the MacBook and uploaded some pictures. At first glance I don't notice anything out of the ordinary. No corrosion, no obviously defective chips/components. One of the batteries looks slightly bloated thought...
