When I press the power key on my early 2008 MBP 15" 4,1 I hear the sound of the DVD drive checking like always but then nothing. I've tried to reset the SMC by removing the battery, holding down power button for 5 sec then reinstalling the battery. That doesn't help. The MBP was running great until today.

    So, you hear no chime and nothing appears on the screen? Is your battery charged and/or are you connected to the AC adaptor which, in turn, plugged into a working wall outlet?

    It's probably a busted drive. I would try holding down the option key while booting, and see if your drive appears.

     

    Try booting into reconvery from a pendrive/CD (make it using a friend's mac, or another mac of your own. Some public libraries will have macs, mine does). Repair permissions, repair the disk, and then click the apple logo in the status bar in recovery. Click the option pertaining to the selection of the boot volume of the computer, and select your internal drive (usually Macintosh HD) and then try booting again.

     

    If that doesn't work, take out your hard drive and mount it externally, and try booting with option.

     

    If nothing has worked, your drive is broken, and you need to take it to a computer place to get it fixed. If you have a solid state (which I doubt because of your OS version not supporting TRIM), your drive is probably messed up and is not fixable (this is a problem with SandForce SSDs)

    No chines. I can just hear the DVD drive running the self check for a second or 2 then nothing. MBP shuts down.

     

    I do have an SSD. I also have filefault 2 enable.

     

    Could this be the faulty Nvidia 8600M I've read about?

     

    Also if I hold down the power key for a few seconds the tiny LED light on the front flashes really quickly.

    thx

    The fact that you get no chime along with the shutdown certainly suggests a hardware problem. Since you are running Snow Leopard would you try booting from your Snow Leopard DVD? If that also doesn't work then take the computer in for repair.

    DVD drive doesn't work along with everything else. Taking it in today to the Apple Store.
