Hi Paul,
You could try Resetting the SMC (System Management Contoller)
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or
Intel-based Xserve
• Shut down the computer.
• Unplug the computer's power cord.
• Wait fifteen seconds.
• Attach the computer's power cord.
• Wait five seconds, then press the power button to turn on the
computer.
