Troubleshooting and Maintenance Troubleshooting Techniques • Reset the notebook-see "To reset your notebook" on page 25. Power and battery problems If the notebook turns off immediately after it turns on • Battery power is probably extremely low. Connect the AC adapter or insert a newly charged battery. If the notebook keeps beeping • The notebook beeps repeatedly when the battery is low (you can set this option in Power Options in Control Panel). Save your work immediately, turn off the notebook immediately, and insert a charged battery or connect the AC adapter. If the battery doesn't charge • Make sure the AC adapter is securely connected to the power source and the notebook, 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. • Make sure the battery is properly installed and locked in place. • Move the notebook away from any nearby heat source. Unplug the AC adapter and allow the battery to cool down. If the battery gets too hot, it will not charge properly. • If available, try another battery and AC adapter. If the notebook has a short operating time • If you are running an application that has an automatic save feature (such as Microsoft Word), disable this feature or increase the specified save time to reduce hard disk access. • 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. 44 Startup Guide
