Troubleshooting Techniques

44 Startup Guide

?? If the operating time has gradually become shorter and the battery is more than a year

or two old, you may need to replace the battery.

?? Heavy modem use or PC card use can affect battery operating time.

?? Use the BIOS configuration utility to make sure I/O Performance is set to Max Battery

Life—see “To run the BIOS configuration utility” on page 47.

?? The battery gauge may need to be calibrated. Restart the notebook, press F6 when the

HP logo appears, and follow the instructions that appear onscreen. This process

calibrates the battery, and requires four to five hours to complete. You cannot use the

notebook during this time.

Startup problems

If the notebook doesn’t respond when you turn it on

?? Don’t use the touch pad while the notebook is starting up or resuming from standby or

hibernation.

?? Connect the AC adapter.

?? Reset the notebook by using a pin or straightened paper clip to press the system-off

switch on the bottom of the notebook. Then press the power button to turn the

notebook on.

?? If the notebook still doesn’t respond, remove the battery and AC adapter, and remove

any PC card. Then reset the notebook using the system-off switch on the bottom of the

notebook, replace the battery and connect the AC adapter, and turn on the notebook

by pressing the power button.

?? If you still get no response, call HP for assistance.

If the notebook won’t boot from battery power

?? Make sure the battery is properly inserted and fully charged. Check the battery’s

charge by clicking the power icon in the taskbar, or using Power Options in Control

Panel.

?? If available, try another battery.

If the notebook won’t boot from the floppy disk drive

?? Make sure the floppy disk is bootable.

?? Make sure the floppy disk drive is selected as the boot device—see “To change the

boot device” on page 26.
