Advice on what to try next with dead MacBook Pro
As described my macbook pro A1260 will not start up. When I press the power button i can just hear the optical drive powering up and if i listen closely I can hear the fans come on and the light at the front edge is on but nothing else; complete silence, no hard drive activity at all.
The battery although not great is charging fine and the green/amber light on power adapter is on when plugged into mains. I have tried all the possible resets to no avail. I have swapped out, swapped around, tried slots one at a time or completely removed the RAM with no difference. About 3 weeks ago the Optical drive stopped working (pulls in a disk, tries to read it makes some buzzing noises then spits it out again) so I tried removing that completely and restarting with no result. I have removed the hard drive and plugged it into the spare slot of my work powerPC PowerMac, it mounts fine and all partitions and files are there, Disk utility and Tech tools pro says the disk is fine.
The powerPc won't let me select it as a startup volume though, it doesn't even come up on the list of drives available but greyed out. I thought this was probably related to the fact that it was formatted and setup in an intel mac and I was trying to start from it on a powerPC- is this the case or may this be where the problem lies??.
Are there any other possibilities?, could it be the HD?, is it just coincidence that the optical drive failed a few weeks ago? or am I looking at replacing the motherboard??.
Any advice is most most welcome
Is this a good question?
