Chapter 4 Problem, Meet Solution 43

Using Apple Hardware Test

You can use Apple Hardware Test to help determine if there is a problem with your

iMac hardware.

To use Apple Hardware Test:

1 Disconnect all external devices from your iMac except the keyboard and mouse.

If you have an Ethernet cable connected, disconnect it.

2 Restart your iMac while holding down the D key.

3 When the Apple Hardware Test chooser screen appears, select the language

appropriate for your location.

4 Press the Return key or click the right arrow button.

5 When the Apple Hardware Test main screen appears (after about 45 seconds), follow

the onscreen instructions.

6 Apple Hardware Test displays an error code if it detects a problem. Make a note of the

error code before pursuing support options. If Apple Hardware Test doesn’t detect a

hardware failure, the problem may be with your software.

For more information, see the Apple Hardware Test Read Me file on the Mac OS X
