I have a macbook pro with os x lion and when I try to startup it shows the initial gray screen and then turns to black and I can't see nothing or do nothing. When I try to startup with safe mode it turns as well to black. Please help me.

MacBook Pro, Mac OS X (10.7.3)

    Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go.


    There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.


    1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”

    2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.

    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
