Chapter 2 - Compaq LTE Elite Troubleshooting
Introduction
This chapter covers troubleshooting information for the computer. The basic
steps in troubleshooting include:
1. Following the preliminary steps listed in Section 2.1.
2. Running the Power-On Self-Test (POST) as described in Section 2.2.
3. Running Computer Checkup (TEST) as described in Section 2.3.
4. Following the recommended actions described in the diagnostic tables in
Section 2.4 if you are unable to run POST or Computer Checkup or if the
problem persists after they are run.
When following the recommended actions in Section 2.2, 2.3, and 2.4, carry
them out in the order given. Rerun POST and Computer Checkup after each
recommended action until the problem is solved and no error message occurs.
(Once the problem is solved, do not complete the remaining recommended
actions.)
NOTE: If the problem was intermittent, check the unit several times to
verify that the problem is solved.
Refer to Chapter 4 for any removal and replacement procedures that are
recommended.
2.1 Preliminary Steps
IMPORANT: Use AC power when running POST, Computer Setup, and Computer
Checkup. A low battery condition could initiate Standby and
interrupt the program.
Before running POST and Computer Checkup, complete the following
preliminary steps:
1. If a power-on password has been established, type the password and press
the Enter key.
NOTE: The key symbol (o--m) appears on the screen when the computer is
turned on to indicate that a power-on password is established. If
the password is unknown, it must be cleared (refer to "Clearing
the Power-On Password").
2. Run Computer Setup (Section 1.8).
3. Position the brightness and contrast control slides approximately in the
center of their range and leave the display open.
4. Turn off the computer and external devices.
