Q: My computer keeps making reboot.

My macbook pro "13" inch keeps making me power off my computer completely and turn it back on whenever I close it. When I open it I'm greeted with a black screen (on but black) with my mouse (I am in complete control of my mouse(sometimes loading). Any help would be appreciated.

MacBook Pro, OS X Yosemite (10.10.1)

    Hi there wildfire399,

     

    If I understand correctly when you wake the computer from sleep, the screen remains black and nothing appears except for the mouse cursor that you can control without issue. From the following article I would recommend that you use these steps specifically, since the rest don't seem to be relevant to your issue:

     

    OS X: When your Mac doesn't sleep or wake

    Reset SMC

    The System Management Controller (SMC) is involved in managing power on your computer. Reset the SMC on your Mac if you are having difficulty sleeping or waking your computer.

    Reset NVRAM/PRAM

    Nonvolatile RAM (NVRAM)/Parameter RAM (PRAM) stores some power-related settings.Try resetting NVRAM/PRAM if you are having difficulty sleeping or waking your computer.

    Test with external devices disconnected

    Some external devices can prevent your computer from sleeping. Try disconnecting items other than your Apple keyboard or mouse from the built-in USB, Thunderbolt and Firewire ports on your Mac. If this resolves the issue, try reconnecting your external devices one at a time until you find the device preventing sleep or wake. Check the documentation that came with the device, or contact the device manufacturer for more information.

    Try Safe Mode

    Check to see if the issue still occurs when the computer is started in Safe Mode. If this resolves the issue, it could be related to a third party software item such as:

    Try another user account

     

    Try creating another user account, or log in as guest. See if your computer sleeps and wakes properly from the additional user account. If it does, your issue may be related to one of the following:

    You can disable login items from the Accounts pane of System Preferences. Try opening only one app at a time in the original user account to determine which app is preventing sleep. If you isolate the issue to a particular app or login item, check its documentation, or contact the developer of that software for more information.

     

    Thank you for using Apple Support Communities.

    All the very best,

    Sterling
