i got an offer locally for a macbook model # MB403LL/A for only 200, the reason he is selling it for 200, is that he spilt coffee onto the trackpad that it effected it internally and now the macbook wont take the battery and if you use a battery the macbook goes to sleep, but it works fine if you just plug in the power cable, and the only other problem is on the monitor there are some discoloration in the bottom right corner. so what do you guys think? Is it fixable? Is it worth the 200? Btw he is not including the hdd. Any help would be great!
