MacBook Pro


Screen Size: 15"

Year: Late 2008

Specs: Unknown


I have aquired a MacBook pro from a friend and it does not turn on at all, I have tested the charger which works fine, changed the RAM which works fine, and even the battery says it has full charge.


I press the power buttong and there is absolutely no sign of power, neither the fans or the hard drive spin up, there is also no error beeps. The laptop is completely dead.


I have read online that it could be a possible graphics chip problem but from my experience with laptops with graphics chip problem (commonly nvidea) they turn on but there is nothing on screen or lines all across it.


I am asking whether or not to waste my time with this macbook, is it a logic board problem?

    If it is a LATE 2008 then the graphics chip shouldn't be the problem as that was on the Late 2007 and Early 2008 models.


    That doesn't mean the graphics chip hasn't failed and taken the rest of the logic board with it. Or simply the logic board has failed which seems to be fairly common for Mac notebooks.


    In other words Yes it is Dead.

    I suggest taking the unit to an Apple store and see if they can determine exactly why the MBP will not turn on.  If they can define the problem(s), you will know if there is any economic sense in investing any time and money. The diagnosis should be free.
