Right. So: some time ago, around last Christmas, I had about a pint of Dr. Pepper spill on my white Macbook 13". The laptop was plugged in, it powered off instantly. I opened up the bastard that night, tried to dry the soda using a hair dryer and cotton swabs, but it wouldn't boot afterwards - just powered on and stayed in sleep mode. Couple of months later I removed a RAM and it booted into the OS, but powered off after about 5 mins and then rebooted, but same sleep issue. Took it to Apple and those half-wits couldn't even tell me what was wrong with it, they suggested a logic board + top case + screen replacement from the start. The thing is, I tried the laptop again a few days ago and it worked flawlessly for about half an hour, eventually powering off again. Tried some movies, music, webcam was working, so was the superdrive. The keyboard, however, did not work at all - neither the buttons, nor the trackpad. Figured it might be disconnected or something, so I plugged in a USB mouse when I noticed the defect. Since then, the Macbook has been doing its sleep routine again, which is killing me !! Anyway, I'm thinking it could be a cooler failure ? Maybe combined with a topcase scrambling ? Could that cause the power-offs ? I'm really not that well off to afford buying another Mac, but I'm not going to settle for anything else either. So please, all ideas are very welcome - help out a sad, macless individual.
