HP Laptop Pavilion Notebook PC Power and Battery Problems

If the computer turns off immediately after it turns on

• Battery power is probably extremely low. Plug in the AC adapter or insert a newly charged battery. If the computer keeps beeping
• The Pavilion Notebook beeps for 15 seconds when the battery is low. Save your work, shut down Windows immediately, and insert a charged battery or plug in the AC adapter. If the computer has a short operating time
• Try conserving power by setting power timeouts to shorter periods. In Windows 98, you can adjust these settings in the Power Management applet in Control Panel (Power Options in Windows ME).
• If you are running any applications with an automatic save feature, such as MS Word for Windows, you can extend the save time or disable this feature to reduce hard disk access.
• If the operating time has become shorter and the battery is more than a year or two old, you may need to replace the battery.
• Set the display brightness to the lowest comfortable level.
• Heavy modem use can affect battery operating time.
• PC card use can affect battery operating time.
• Check the Power Management settings in BIOS Setup.

1. From the Start menu, shut down, then restart the computer.
2. When you see the HP logo, press F2 to enter the BIOS Setup utility.
3. From the Power menu, make sure Enable Power Saving is enabled.
4. Exit the BIOS Setup utility.

If the battery doesn’t charge

• Make sure the AC adapter is plugged into the power source and that the light on the adapter is on.
• If you're using a power strip, remove the AC adapter from the power strip and plug it directly into a wall outlet.
• Check that the battery is fully installed and locked in place.
• Turn off the computer, then check that the battery contacts are clean and that the AC adapter cables are fully plugged in.
• Move the computer away from any nearby heat source. Unplug the AC adapter and allow the battery to cool down. An elevated battery temperature prevents charging.
• If available, try another battery and AC adapter.

If the Time Remaining percentage for the battery is not correct

• When you place the pointer on the power (battery) icon on the Windows taskbar, you will see the percentage of remaining time left on the battery. The Smart Battery feature calculates the Time Remaining by dividing the battery capacity by the real time power consumed by the system. In other words, this percentage reflects the task you are performing at the moment. For example, if you are doing something that consumes a lot of battery power (such as reading a CD-ROM or DVD), the Time Remaining percentage will be lower than if you were performing a task that doesn’t require as much power. (The system assumes you will continue with this same task until the battery runs out.) Therefore, the Time Remaining value should be viewed as an estimate, not a precise value.

If the computer stops responding

• Press CTRL+ALT+DEL to end the application that is not responding.
• Press the blue power button for at least 4 seconds to turn off the computer. Then press the blue button again to turn the computer back on.
• If nothing happens, insert a paper clip into the system-off button on the bottom of the computer. Then press the blue button to turn the computer on.

If the computer doesn’t suspend as expected

• If you have a connection to another computer, the computer doesn’t suspend if the connection is actively in use.
• If the computer is performing an operation, it normally waits for the operation to finish.

You may also want to test the power management system with diagnostics. See Testing Hardware Operation.

HP Laptop Pavilion Notebook PC Printing Problems

For most printing problems, use the Print Troubleshooter in Windows Help.

If a serial or parallel printer doesn’t print

• Check that you are using a proper cable or cable adapter, and that the printer is on.
• Check for paper in the printer or other printer errors.
• Make sure the printer cable is secure at both ends.

If the left edge of printed output is missing

• If the printer you are using is a 600-dpi (dots per inch) printer, try selecting a compatible printer driver for a 300-dpi printer. For example, for a 600-dpi HP LaserJet printer, try using the HP LaserJet IIIsi driver (300-dpi). Certain applications may not work properly with 600-dpi printers.

HP Laptop Pavilion Notebook PC Recovery CD Problems

If an error message “Windows cannot find wordpad.exe” appears after inserting the Recovery CD

• The system is trying to open the readme.doc file in WordPad, but cannot locate the wordpad.exe program file. Under Windows 98, this error message may appear after inserting the Recovery CD.
