MacBook air starts, but after restart fan just start/stops

Hey guys,

So i did a replacement of the logic board because the other was water damaged.

so far, so good. I then turned it on and the startup chime came, run the diagnostics and it said there is a problem with the battery and it needs a firmware update.

Restarted but this time the fan just starts/stops. If i unplug the battery it will start correctly again, but when i shut it down then the same happens. Tried doing SMC reset, but when i reset the pram, it does restart at the startup chime, but then fan start/stop again.

Tried replacing the fan but didn't solve it.

Been running and using the computer for an hour now, and no problems, except when i restart i have to unplug the battery, to get the fan spinning and computer starting normally.

Edit:

Tried turning the macbook on just with charger and unplugged battery, does the exact same thing. Just closing the lid and opening again works fine, as long as it's not shutdown or restarted.

Hi @timothymcevoy

Here is the pictures of the connected logic board. as far as i can see everything looks good, and works fine, ecxept after i restart the computer, then it wont start.
