Using Apple Hardware Test

If you suspect a problem with the MacBook Pro hardware, you can use the Apple Hardware Test application to help determine if there is a problem with one of the computer’s components, such as the memory or processor.

To use Apple Hardware Test:

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

2Restart your MacBook Pro while holding down the D key.

3When the Apple Hardware Test chooser screen appears, select the language you want to use.

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

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

6If 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 doesn’t detect a hardware failure, the problem may be software related.

If this procedure doesn’t work, you can use Apple Hardware Test from the Applications Install DVD that came with your computer. For more information, see the Apple Hardware Test Read Me file on the Applications Install DVD.
