Turns on but won't fully boot (USB won't boot either)

Hi guys,

I’m working on the above macbook which has a small water spill.

After an SMC reset, the macbook does turn on.

I cannot

  • Get past login screen (if I click guest account or main account, it just stays loading forever)
  • Get past USB installer loading bar. It also gets stuck on the apple logo with the bar when trying to boot from an installer.

I took out the logic board, took pictures of the damage, cleaned off the corrosion, and still nothing. I’m curious what would cause a Macbook Pro to turn on and start booting but not get anywhere else? It can’t be the drive since USB also does not work.

Thank you for your help, everyone

Is it detecting the battery properly? On the login screen it should show a battery charging symbol and not a triangle or X symbol. This model in particular needs a working battery plugged in for the MacBook to work normally (else it shuts off during login)

Hi @benjamen50 ,

It does detect the battery and will boot with just battery alone as well
