Can I swap drives and get the system and applications running?

I have a MacBook Pro 13" Early 2011 (2.3 GHz) which has a damaged logic board due to liquid spill. I have tried to rescue the board by cleaning and drying but no luck. (Background info: I am trying to save the system for a friend.)

Now, it seems I can get another working MacBook Pro 13"(same model, early 2011) for a reasonable price.

If so, can I swap the drives from the damaged machine to the working one and get all the applications on the drive up and running again?

The reason I am asking is that I read somewhere that you may need to re-authorize the applications if you swap HDDs between different MacBooks. I seem to recall it was between different models, though. Anyone know if this would happen in my case?

You will not need to reauthorized the majority of your APPS by just moving the hard drive. The only ones you may have problems with would be possibly Adobe products.

I dont think so as that would be strange. It should work with no issues. Its possible that the apple apps like imovie, garageband, etc might have issues (although im not sure and that would be strange if it did) but all others should be fine.

And for the macbook with liquid damage, https://www.youtube.com/watch?v=Ef2tvcqy... that video should be a basic guide on what to do to try and revive it. The part that you want to worry about is the motherboard. Give that a shot, it cant hurt something thats already dead.

@mayer , that work too, i just prefer videos as im more of a visual learner and i find it easier to see whats going on rather than to just read what i should do as ive made some mistakes reading before.

Thanks. I did remove the logic board and cleaned it using electronics cleaner (IPA), basically follwing the Electronics Water Damage guide as suggested above. No luck. I know my friend tried to start it after the spill and I think that fried something on the logic board. It looks burned in one spot and still does not start after cleaning and drying, so I thinks it's toasted... Anyway, thanks for the comments.

Thats what it sounds like. When liquid is spilled, NEVER turn on the electronic. Im sure you know that, but please tell your friend so he doesnt do that again.
