4.2.3.2 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 4-2.

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 Main Board and may

require board removal/replacement.

Try running PC-Doctor (Paragraph 4.2.5.3) if possible to verify the source of

problem. Otherwise, replace the Main PWB.
