Using Apple Hardware Test

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

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

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

Restart 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.

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

If 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.
