My MBP does even make the chime sound at boot up after installing 10.6.2. I hear the dvd drive make the usual start up noise and I hear brief access to the HD. Then the screen goes black. Tried PRAM and SMC reset, no dice. Genius Bar told me that it's hardware related and it will cost me $330 to fix. I just find it really odd that died right after the update. Does anyone think it has anything to do with the graphics card failing, or is it something else?
Does anyone know if there is any way to boot from the DVD drive and try to do an archive and install from the DVD? I hear the DVD drive start up when I power on, but I'm not sure if I want to take a chance of having the DVD get stuck in the drive because the machine won't boot up. If this won't work, can I still do a "target disk mode" and try to recover my data with another mac?
