Using Apple Hardware Test

You can use Apple Hardware Test to help determine if there is a problem with your computer’s hardware.

To use Apple Hardware Test:

1Disconnect all external devices from your computer except the keyboard and mouse. If you have an Ethernet cable connected, disconnect it.

2Insert the “Additional Software & Apple Hardware Test” disc that came with your computer.

3Restart your computer and hold down the “C” key as it starts up. A list of available startup volumes appears. Click Apple Hardware Test and click the right arrow.

4When the Apple Hardware Test main screen appears after about 45 seconds, follow the onscreen instructions.

5If Apple Hardware Test detects a problem, it displays an error code. Make a note of the error code before pursuing support options. If Apple Hardware Test does not detect a hardware failure, the problem may be software related.

For more information about Apple Hardware Test, see the Apple Hardware Test Read Me file on the “Additional Software & Apple Hardware Test” disc.
