water spill on laptop, what parts can I salvage ?
Spilled water on laptop. I let it dry for 2 weeks and it still wont turn on. I think it is FUBAR. Im planning to dismantle it. Need to know what parts I can salvage/reuse.

Water moisture may still be inside, but that can cause metal corrosion on circuits, so wherever there’s corrosion it’s a problem. You can possibly save the memory, wireless cards, CPU.
