Last summer my daughter gave her Mac Book a drink of coffee. Of course it had the French Vanilla gobbly gook in it with added Honey. Sweet, sticky, mess. I was downstairs when I heard her say Oh Golly Gee! She promptly took apart what she could, turned it upside down in the sun to dry out. Put it back together and it worked for about a week. Then nadda! So I took it in to the local Apple repair place and was told that the logic board had been Fried. Golly Gee! So with the help of Fix-it I put in a used Logic board and sent them off to college. When she came home for Christmas I saw her shaking it. And of course asked "whats up with that?" She said the Mac wouldn't boot and sometimes this helps. So I figured the thing was shot, got her another lap top and back to school they went. I thought maybe the hard drive had a sip of coffee as well so I ordered the hard drive up grade kit and thought I might as well double the RAM too since I'm this far into it. I first put the RAM in and reset the pram with with the discs that came with the machine and Viola it was booting just fine. Went ahead with the hard drive clone and installed that. Everything seems to be working good so far. But now my daughter wants it back. HMMM!
The repairs went very well with the help of the excellent step by step guides on you web sight.
Don't give your lap top a sip of coffee. If your Mac Book doesn't boot up right try resetting the pram with installation discs.
