2-2 Troubleshooting
2.1 Preliminary Steps
IMPORTANT: Use the external power supply when running POST, Computer Setup, or
Computer Checkup. A low battery condition could initiate Hibernation and interrupt
the test.
Before running POST and Computer Checkup:
1. Obtain established passwords. If you must clear the passwords, go to Section 2.2.
2. Ensure that the hard drive is installed in the computer.
3. Ensure that the battery pack is installed in the computer and the power cord is
connected to the computer and plugged into an AC power source.
4. Turn on the computer.
5. If a power-on password has been established, type the password and press Enter.
NOTE: The key icon appears on the display when he computer is turned on to indicate
that QuickLock/QuickBlank has been initiated. Type the power-on password to exit
QuickLock/QuickBlank. If the password is unknown, it must be cleared (see Section
2.2).
6. Run Computer Setup (Section 2.5). If a Setup password has been established, type
the password and press Enter.
7. Use the Hotkey (Fn+F10) to adjust brightness to midrange and leave the display
open.
8. Turn off the computer and all external devices.
9. Disconnect external devices that you do not want to test. If you want to use the
printer to log error messages, leave it connected to the computer.
NOTE: If a problem only occurs when an external device is connected to the computer,
the problem could be with the external device or its cable. Isolate the problem by
running POST with and without the external device connected.
10. Use Compaq Utilities to test these ports.
To run Compaq Utilities:
a. If you are running Compaq Utilities from the hard drive, turn on or restart the
computer. Press F10 when the cursor appears in the upper right corner of the
screen. If you do not press F10 in time, restart the computer and try again.
If you are running Compaq Utilities from diskette, insert the Compaq Utilities
diskette in drive A. Turn on or restart the computer.
b. Press Enter to accept OK.
c. Select Computer Checkup (TEST).
d. Select Prompted Diagnostics.
e. After “Identifying System Hardware” completes, select “Interactive Testing” and

Troubleshooting 2-3
2.2 Clearing Passwords
The power-on password prevents use of the computer until the password is entered.
The setup password prevents unauthorized changes to Computer Setup. To clear the
passwords, you must remove all power from the system board. If you do not know the
passwords, use the following procedure to clear the password:
1. Remove all battery packs from the battery bay and DualBay, if applicable.
2. Disconnect the external power supply.
3. Remove the real-time clock battery.
4. Wait five minutes.
5. Reconnect the external power supply.
6. Restart the computer. During Power-On Self Test (POST), a “162 System
Options not set” message appears.
7. Shut down the computer, then disconnect the external power supply again.
8. Replace the real-time clock battery.
9. Install the battery pack(s).
10. Proceed with the troubleshooting procedures.
2.3 Power-On Self-Test (POST)
The Power-On Self-Test (POST) is a series of tests that run every time the computer is
turned on. POST verifies that the system is configured and functioning properly.
To run POST:
1. Complete the preliminary steps (Section 2.1).
2. Turn on the computer.
If POST does not detect any errors, the computer beeps once or twice to indicate that
POST has run successfully. The computer boots from the hard drive or from a bootable
diskette if one is installed in the diskette drive.

2-4 Troubleshooting
2.4 POST Error Messages
If the system is not functioning well enough to run POST, or if the display is not
functioning well enough to show POST error messages, refer to the Troubleshooting
tables in Section 2.6.
If POST detects an error, one of the following events occurs:
■ A message with the prefix "WARNING" appears, informing you where the error
occurred. The system pauses until you press F1 to continue.
■ A message with the prefix "FATAL" appears, informing you where the error
occurred. After the message, the system emits a series of beeps and stops.
WARNING messages indicate that a potential problem, such as a system configuration
error, exists. When F1 is pressed, the system should resume. You should be able to
correct problems that produce WARNING messages.
IMPORTANT: When a WARNING message includes the prompt to "RUN SCU," press
F10 to run Computer Setup. (Computer Setup replaces the SCU utility.)
