Help! My MacBook Pro which is only a year old was working fine, the only small problem was that it wouldn't play a video, so I restarted it but it never came back on. So I restarted it manually, the small light on the edge lit up, the screen with the apple came up along with the load bar, the empty load bar flashes a couple of times then the computer totally shuts off. Have turned starting in safe mode, same thing. Have tried starting holding down apple + option + R + P when turning on, same thing, have started starting up with the install disc in, same thing. Please can anybody help. Thank you.

MacBook Pro, Mac OS X (10.6.6)

    The startup volume has directory damage that can't be repaired. What backups do you have?

    The inevitable result of not backing up is that you will lose all your data. That may already have happened. The first thing you have to do is create a backup, if it's still possible. Below are some suggestions.


    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.

    I do have the exactly same problem but I do have made a backup in an external drive. Other than that exactly same situation as LizPoole. What shall I do now?

    LizPoole - just curious, what did you end up doing? I know it's been 18 months or more, but the SMC reset is done *without* the battery and without the power plugged in. You uplug the cable, remove the battery, press the power button for five seconds and let go. You will see/hear nothing from the computer while you do this. Then you reconnect the battery/cable and see if that helped.


    Linc - I think your diagnosis and subsequent scolding is over the top. The fact of the matter is that it's very likely Liz's disk is *not* completely lost and to say otherwise is irresponible and fear-mongering, especially without further discussion.


    You tell her how to launch Disk Utility, but why not first do a Repair Disk and Repair Permissions? That might solve the problem of "directory damage."


    I came to this thread today because I have a client's computer in a similar situation. I've removed the disk and it's 100% fine. The problem is with the motherboard or something else.
