My USBs ports are charging all devices like my iPod and my back-up external Hard Drive but the Mac does not recognise any of them.
The Hardware Test showed the following error: 4SNS/1/40000000:Th 1H-81.000.
What does this mean?
It means one of the internal sensors has failed or become detached.
Thanks for the prompt reply Kappy...
Does this mean I have to hand in my Mac for repair or is there a way to solve it independently?
You need to take it in for repair. This is not user servicable.
Does the AppleCare Protection Plan cover this, do you think?
Yes, if it's still under warranty.
Thanks for all the help!
I'm facing a similar problem. Can you tell if you needed to replace your logical board?
