Chapter 4 Problem, Meet Solution 51

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:

1 Disconnect all external devices from your computer except the power adapter.

If you have an Ethernet cable connected, disconnect it.

2 Restart your computer and hold down the D key as it starts up.

3 When the Apple Hardware Test chooser screen appears, select the language 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 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 doesn’t detect a

hardware failure, the problem might be software related.

For more information about Apple Hardware Test, see the Apple Hardware Test Read

Me file on the Mac OS X Install Disc 1.

Problems with Your Internet Connection

Your MacBook Pro has the Setup Assistant application to help walk you through setting

up an Internet connection. Open System Preferences and click Network. Click the

“Assist me” button to open Network Setup Assistant.
