My Macbook Pro 13 refuses to turn on after i place it in sleep mode by closing the lid, after opening the lid the led sleep indicator is still on and the screen hasn't revived but once i press any button to revive it, it goes off and refuses to turn on. Is there a way to fix this?

MacBook Pro, OS X Yosemite (10.10.2)

    Hello Carlens J,

     

    Thanks for visiting Apple Support Communities.

    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:
