"
Hard drive alert--provides 72-hour advance warning of impending hard drive problems and can automatically start optional backup software. Alerts can be enabled, disabled, and tested, and software can be set to back up information whenever a hard drive alert occurs. System temperature alert--reports overheating. As the system temperature rises, this feature first adjusts fan speed and other cooling components, then displays an alert, then shuts down the system. Battery pack alert--reports charging problems and battery pack failure. A battery charging problem alert is reported only on the computer display. Monitor alert--diagnoses and displays external monitor operational problems. Memory alert--reports memory board configuration changes when a memory board is removed, added, or reconfigured. It also provides the previous and current configurations for comparison. While the computer is connected to a network, alerts pop up on the computer display and are simultaneously reported to the network console. If the computer is not connected to the network, the user will receive a local alert.

For ventilation, an electrical fan is installed. The fan operates on from 5 to 12 volts and is controlled by a temperature sensor. The fan is designed to turn on automatically when high temperature conditions exist. These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software applications. Exhaust air is displaced through the ventilation grill located on the left side of the computer.
CAUTION: To properly ventilate the computer, allow at least a 3-inch (7.6 cm) clearance on the left and right sides of the computer.

T ROUBLESHOOTING
Follow these basic steps when beginning the troubleshooting process: 1. 2. 3. 4. Complete the preliminary steps listed in Section 2.1. Run the Power-On Self-Test (POST) as described in Section 2.3. Run Computer Setup as described in Section 2.5. If you are unable to run POST or if the problem persists after running POST, perform the recommended actions described in the diagnostic tables in Section 2.5.
Follow these guidelines when troubleshooting:
I I I I I
Complete the recommended actions in the order in which they are given. Repeat POST after each recommended action until the problem is resolved and the error message does not return. When the problem is resolved, stop performing the troubleshooting steps and do not complete the remaining recommended actions. Refer to Chapter 5 for recommended removal and replacement procedures. If the problem is intermittent, check the computer several times to verify that the problem is solved.
The following table describes the troubleshooting actions:
If You Want To:
Check for POST error messages Perform any of the following: I Check the system configuration I Set the system power management parameters I Return the system to its original configuration I Check system configuration of installed devices
Then Run:
POST Computer Setup
Troubleshooting 2-1
2.1 Preliminary Steps
IMPORTANT: Use AC power when running POST or Computer Setup. A low battery condition could initiate Hibernation and interrupt the test. Before running POST, complete the following steps: 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. 6. Run Computer Setup (Section 2.5). If a Setup password has been established, type the password and press Enter. 7. Turn off the computer and all external devices. 8. 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. 9. Use Compaq Utilities and loopback plugs in the serial and parallel connectors if you plan to test these ports. Follow these steps 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 Prompted Diagnostics. d. After "Identifying System Hardware" completes, select Interactive Testing and follow the instructions on the screen.
2-2 Troubleshooting
2.2 Clearing Passwords
1. 2. 3. 4. 5. 6. 7. 8. 9. Turn off the computer. Disconnect the AC Adapter (refer to Section 5.3). Remove the battery pack (Section 5.6). Disconnect and remove the Real Time Clock (RTC) battery (Section 5.11). Wait five minutes. Reconnect the RTC battery. Install the keyboard deck and keyboard assembly. Reconnect the AC Adapter. Do not reinstall the battery pack yet. Turn on the computer.
NOTE: Remember to set the date and time the next time the computer is turned on.
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, complete the following steps: 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.
Troubleshooting 2-3
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:
I I
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, then stops. The system emits a series of beeps, then stops.
