Kid Killed my MacBook

[Angrboda]

Similar to what poca said, it's hard to say from the information given. Sorry to hear about the loss. I've never owned or disassembled a macbook, so I have no idea if it's easy or hard. And unfortunately, unless you have the right diagnostic tools, or spare parts to test with, it's almost impossible to determine what the specific fault is. If disassembly is not too difficult, I'd likely pull it all apart, clean as much as I could with distilled water and/or other fluids. (Most fluids aren't conductive and leave negligible residue, so they're safe as long as you dry thoroughly afterwards.) Then I'd put the main board in distilled water and leave it for a week or so; then, flush it out with more water (probably tap water, to remove the gunk, followed by distilled water). The power supply is probably toast, but if you're following the procedure up to this point, and you've examined the board to make sure that there is no obviously visible damage, take the second-hand power supply you previously acquired (you did remember to acquire one like I didn't tell you, didn't you?), and hook up the minimum necessary components. Then, retreat behind the blast shield, and flick the switch. If it doesn't come to life, then I'd toss it, or sell it on eBay for parts.
