Hello,
I have a 13" Macbook Pro that I cannot get to boot or even activate the cooling fan.
For clarity and transparency, it has had coffee spilled on the keyboard at some point in the past.
So, initially when the power cord was connected there was no green light on the cord end.
Pressing the power button did nothing whether plugged in with the battery connected or with the battery disconnected.
I removed the MB and connected it to the power cord by itself and no green light or fan spin.
I bought a replacement MB and now I have a solid bright green light on the cord end, but no fan spin regardless of leaving it sit or pressing the power button. This is true regardless of being fully connected in the chassis or by itself on the bench.
I tried all the tricks with plugging and unplugging and connecting the battery and all the ctrl+shift+option as well as holding power and plugging in power cable and connecting battery, and none of it makes any difference.
I disassembled the keyboard all the way down and and cleaned it thoroughly by soaking it in a mild solution and then soaking it in alcohol and then drying it in front of a fan for an hour. Reassembled everything and still no dice, but was kind of expecting that since I get no fan spin whether in the chassis or not.
I also tested my original MB by plugging in the power jack from the replacement board and I still had no light on the cord with that board, so pretty sure it's probably bad as both the old power jack and new power jack give me a solid bright green light with the new board.
At this point I can only assume that something is wrong with the fan and/or fan connector.
I've watched countless videos and read numerous forums and everything tells me I should at least be getting a fan spin with the board plugged in without it being in the chassis.
The replacement board was supposedly pulled from a known and confirmed working unit.
It doesn't seem logical that it would be a board level issue if it is in fact a known good replacement, but I just can't figure out what else it could be.
If anyone can offer any insight or practical advice I would be extremely thankful.
