Self Test Beep Messages - Texas Instruments TravelMate 5000 Series Maintenance Manual

4.2.3.2
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.
