• 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.
• 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.
