Hello,
I left my macbook pro ( early 2008, core 2 duo 2,5ghz, 17") to a friend, i know it's the first mistake
.
A new update ask him to install and restart, and after a while the laptop seemed to freeze during the install so he press the power button to force the shutdown.
Of course now the laptop won't start.
When you start it you can't ear no chimes, the screen stay black and the little light in the front stay bright white. I can ear the fan spinning and the hard drive starting.
I test the ram, reset the smc, and reset the pram but i still won't ear no chimes.
I tried to boot on a tiger disc but didn't work, tried from a leopard install on an external hdd in firewire didn't work, tried to connect it in target mode to an other macbook pro but doesn't appear on the desktop.
I plugged an external screen but still nothing coming on.
I tried the single user mode, the verbose mode.
But still a black screen.
I looked a lot over internet with no good answers. I called apple support, but they didn't give no help.
So here is my question:
- Is it possible that the update was a firmware update for the graphic card or the logic board ?
- If there is no chimes, black screen, white light in front steady, what did happen during that update ?
Thank you in advance.
(MAJ):
I open the laptop, put the hard drive on external on my other laptop, he works i can access all the files, so i have been able to backup everything .
- Is there a way for me to fix the hard-drive system or boot from my laptop, so when i put it back in the laptop he should work again ?
- Do you think, now that everything back-up i should format it in HFS+ from the working laptop ? But until i wasn't able to boot on the cd, does a format hard-drive would change anything ?
I also figure out, it have a nvidia 8600mgt 512 early 2008, is it the series who was giving a lot of graphic trouble ? In some case the graphic card would even died, is it possible it is one of my problem ?
Thanks
