Print these instructions: Click the Share button
in the Help window, then choose Print. Disconnect all external devices except the keyboard, mouse, display, and speakers. If you have an Ethernet cable or external DVD drive, disconnect it.
Choose Apple menu > Restart, then hold down the D key while the Mac restarts.
When the Apple Hardware Test chooser screen appears, select the language you want to use, then press the Return key or click the right arrow button.
If you don’t see the chooser screen, Apple Hardware Test may not be available on your Mac. You may be able to start Apple Hardware Test from the Internet. Reconnect your Mac to the network, then restart your Mac while holding down both the Option and D keys.
When the Apple Hardware Test main screen appears, follow the onscreen instructions.
If Apple Hardware Test detects a problem, it displays an error. Make a note of the error before you call Apple Support.
