Won't boot after battery replacement

Hi all,

two years ago my MBP was diagnosed "dead" because of oxidized motherboard (a terrible accident including me, a glass of water and... my cat).

So, last week I tried to boot up after 2 years, and it boots up ! (seems to work well)

But the battery was bloating, so I decided to replace it.

Now my problem is :

- If AC adpater plugged but no battery connected = Boot

- If I connect the battery + plug AC adapter = Boot only the first time

- I can "restart" my computer, I can't "shutdown" + press power button

- When my computer is running, I can plug off AC adpter, no problem (I can see charging percentage on system tray)

- I can also see charging percentage with leds on the computer side

What can I do, any Ideas ?

Hi!

I'd suggest that you take you MacBook apart until you have full access to the main board. Then use some Q-tips and some rubbing alcohol to wipe any traces of water damage - anything that looks suspicious.

This is how to dismantle it.

Water damage is a pretty serious issue for computers. I would suggest taking it to a local service center to have them conduct a diagnostic. The water has had 2 years to settle in your computer, it could have oxidised several components, made connections and caused shorts, and left other residue in your computer.

It might take some pretty hefty repairs to get it running 100% again.

If you feel confident, go ahead with @alexniculescu 's suggestion, and attempt a cleaning yourself, but I would not get my hopes up for that one.
