[Closed] MacBookPro help required...

I have a 4 1/2 year old MacBookPro that though still in very good condition, has suffered a slight setback for one reason or another. somehow, I don't know how but I wasn't around when it happened, some liquid (looked like water) got onto the keyboard, and obviously its not been quite right since.

Now I let it dry in the airing cupboard for about 5 days after that happened, then tried booting it. Success, it booted! Woohoo. Except one (or many) of the keys were constantly being pressed (or so the computer thought)... I tried a few things, but quickly gave up.

Fast forward a couple of months, I've given it another go. Anyhow, I've stopped whatever keys it was from seeming like they were constantly being pressed (just repeatedly pressed every key HARD several times when the computer was switched off) and it seems to function ok, except most of the keys don't seem to work at all now.

So I plugged the keyboard in from my G5 PowerMac, and it seems to work fine. Whopee, I can actually use it of sorts now... But obviously I want to get it fixed properly.

What do I need to do? Is it new keyboard time? Or do you think I can fix it without a new keyboard, as I had a quote today from local Mac specialist of £125 for the parts and about £60 for the labour!!! Which when you consider that it needs a new battery too (about £100) and even fully functioning it's worth only about £350 on ebay I reckon, it don't seem worth it! I'm probably going to buy a Mac Mini anyway soon, but need to try and fix this so I at least get some decent dollar back for it...

Or anybody want to give me £300 for an otherwise perfect MacBookPro (15.4", 2.16GHz C2D, upgraded 320GB 7200rpm WD Black HD, 3Gig Corsair RAM) with a duff battery, and a keyboard that needs a fix?
