[primoz1]

Hi again. This laptop it power Up but screen is black, fun spins on full power al the time and DVD start, and no shows other signs of life.

Is that nvidia defect or some other, I ask because I see a lot of videos on youtube and in almost all nvidia cause this defect.

Is any suggestion, how to resolve this problem ?

Thank you.

Re: Macbook pro 15 black screen.

Aha, so this is probably defected OS problem or bad HDD ?

Re: Macbook pro 15 black screen.

Yes. This is the sign that the OS cant boot. You can take out the disk and boot from Hiren and do a disk check. If the disk is OK you have to reinstall OS. The best way to install OS is to download MacOS and make a bootable USB stick (the optical drives on this ones are problem prone).
Boot from the stick and enter disk utility. Partition the disk as GUID and make a HFS partition. Install the MacOS and everything should be OK.

Hi. I use hiren's boot CD and boot OK, but no one tool can start (some error) but HDD is still in laptop. Whole thing is heating too much for my opinion (like 70 deg celsius) ? I got feeling to somethig wrong with GPU, maybe reball was not successful ?

So what can I do to exclude defective motherboard ?

Im not familiar with Mac at all.

Thank you.

Did you clean the coolint system? Do both vents work fine?

Hi. I try without HDD and work OK http://youtu.be/ymXDsgp44eE

Fans and cooler is clean no dust etc. fresh thermal paste but still is little warm for my taste, but I hear that serie is heated a lot.

I dont have any MAC OS dvd etc. (is not my laptop) so I cant test is hdd or corrupted OS.

Thank you.

Re: Macbook pro 15 black screen.

I think (because I have one) that these laptops are built to use the casing as a heatsink.
If it had an nVidia 8600m, it might have been covered by Apple for free repair, but you've got it fixed anyway.

Hi. I get laptop to repair and I dont ask if is under warranty, if owner does not care, I dont care either

Re: Macbook pro 15 black screen.

Just looking at this post. I have an Apple powerbook G4, do you need a special lead to connect your hard drive to an intel based laptop? I just notice they look like a special Apple connection but might be wrong.

Re: Macbook pro 15 black screen.

Hard drives in all Intel Macs are SATA. The one in your PowerBook will be IDE. You are best off putting your PowerBook hard drive in a 2.5" USB to IDE enclosure and pulling the data from it.
