My girlfriend has a MacBook, with various issues (heat, whine, moo, pop) but she also has an issue that i've not read about (i read the forum everyday) The MacBook's will not come back on after a restart. The screen stays black whenever she has to restart or shutdown. Applecare told her to reset her PRAM, both for the speaker pop and the black screen, but they both worked for a short time, but now are back. It's extremely frustrating, as we were excited that Apple released a firmware update, then after restarting the damn thing wouldn't come back on... Any others out there with this problem? What is the remedy? Should she demand that Apple take a look at it after all the issues she has? Thanks in advance, Rich.
