How to test if the motherboard's dead?

Hi,

I have a (now) old MBP that I didn't want to throw out or sell for pennies, so I decided to convert it into a server. Took it apart, no issues there. I'm now trying to test if it's working. To clarify, it powered on and everything worked before taking it apart.

Unfortunately, nothing happens when I press the Touch ID button underneath (to power it), I even connected the screen back and nothing.

QUESTION: Is there a way for me to test if it's dead or not? Should it even power on in this state, or does it have some checks that won't let it?

Only one side of the USB C ports, the touch ID, and the screen are connected.

What could have happened that it just went kaput when dissembling it? There's nothing broken/cracked on the motherboard, at least visibly.

All good guys, I think its ded. It shows between 5 (when the power button is connected) and 20 when it's not connected, but the display stays pitch black. What value should the meter display?

When you were disassembling it, is there a possibility that you may have done something to short circuit the board? I myself did that once accidentally while disassembling this exact model, accidentally picked up some static charge on my hands from something without realizing it, and then touched the board.

use a usb-c amp meter to check what voltage and current its taking

Connected an USB C cable to the other port to charge an iPhone but there's no power draw, phone does not start charging.

@digger92567 - Sadly, you really can’t convert a MacBook Pro logic board into a server. Removing the logic board severs SMC from its sensors so SMC will go into CPU SAFE MODE and with enough sensor failures it won’t allow you to restart as SMC will go into its latched state.

You can check to see if it's receiving power by touching the heatsink over the processor and feeling if it's warm. The logic board could be at risk of overheating too if it is left powered on for too long without fans attached. Theoretically though I think it should work in the configuration you have it in, so it's possible it may have been damaged during disassembly. Have you tried reinstalling it fully into the computer again to see if it still works in its original configuration? If it doesn't, then you know something has been damaged in the process. Good luck!
