Using Apple Hardware Test
If you suspect a problem with the MacBook 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 Insert the Mac OS X Install Disc 1 that came with your computer.
3 Restart your computer and hold down the D key as it starts up.
4 When the Apple Hardware Test main screen appears, follow the onscreen instructions.
5 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 may be software related.
