Macbook A2992 not power on after force to reset

[chrisfoliaki]

'm new here. My work MacBook was running a little slow, so I forced a reset. Since then, it won't power on. When I plug in the charger, the light stays orange. I tried to revive and restore it using my Mac mini M4 via a Thunderbolt cable, but the process failed. I’ve attached a screenshot of the error.

I opened the back cover and unplugged the trackpad. When I plugged in the charger, both fans started running at full speed.

About three months ago, I spilled water on my MacBook. I quickly cleaned it and turned it upside down, and nothing seemed to be wrong at the time


So I need help I have multimeter, solder, blower and micscrope here I can do any instructions to making test now.

Appreciate your assistance here!

First of all, welcome to the forum!

Machine could run slow because of some sensor issue; caused by corrosion.
Max fans speed disconnecting trackpad is normal; CPU can't communicate with thermal sensors from trackpad board.

I recommend to test with known good trackpad board/flex.

Noted, I will order a new trackpad board/flex and post the results
