Chosen Solution

Hey, I recently got a MacBook Pro which I was asked to check if it could be fixed. The laptop suffered water damage a while back, but still functions with the exception that it cannot detect the internal SSD anymore. The internals look ok, except for some residue on the battery chip, but I’m not sure if that’s causing the issue. (I believe it’s simply leftover glue from the plastic cover that should have been there originally. (It was already removed when I opened it.)) How can I test if the SSD is simply faulty or if oxide (or something else) is to blame?

P.S.: Unfortunately I do not have a spare SSD with that specific interface to test. UPDATE: Added a picture of the underside of the logic board. No clear signs of damage. There is a light stain, but I’m not sure if it’s due to the water.

Thank you.

Try booting from an external USB drive. The last water damaged retina I got in had fried the storage board and I had to order a new one from Other World Computing and that fixed it. Of course you do need to disconnect the battery and remove that corrosion first.
