MacBook suddenly power off or freezes.
Hey,
just got a new MacBook on ebay, the seller already said that it freezes sometimes or restarts unexpected. But he doesn't know if its RAM or Logic Board.
I have 14 days returning policy by the way ;)
I switched RAM and HDD (there was a 320 Gig HD installed, used the old one from my "destroyed" MacBook (this time it worked and I checked the screws thousand times ;) ). But it still freezes randomly. Then I need to restart sometimes 9-10 times (mostly it freezes right after pressing power Button, the Optical Device (CD) doesn't try to spin up) and then it works for 2-3 hours, then it goes mad again. The seller hasn't explained that the CD Device is not working properly (I need to PUSH insert CDs, but they are ejecting well)...
Anyone can help me? Can it really be the LogicBoard? I mean what should be damaged? just a loose cable?
Or is it PRAM Battery wich is damaged or empty? It saves time when not on Power, but that and Resetting SMC mostly fixes (Or creates) the boot Problem
Is this a good question?
