5.3.3.2 Self Test Beep Error Messages

In the event of a hardware problem that affects the display, the Notebook also communicates errors

via a series of beeps. These codes may be heard over the system's speaker as three bursts of

beeps. The interpretation of the beep codes is provided in Table 5-3.

To recover from a self test error, try cycling power to the computer. Also, press Ctrl-Alt-Esc to

ensure that the Setup configuration is correct. In general, most of the failures are associated with the

Motherboard and may require board removal/replacement.
