24 Troubleshooting and Diagnostics ze1000 Series Troubleshooting and Self-Repair Guide
• Some file browsers respond slowly while processing graphics or waiting for broken network
connections to time out.
• If the notebook’s hard disk drive runs frequently (as indicated by the hard drive light on the front
of the notebook) while the notebook appears to be paused or running slowly, Windows is likely
spending excess time writing to its swap file on the notebook’s hard disk. If this occurs
frequently, consider installing additional memory.
• Check the amount of available free disk space. Delete temporary and unneeded files.
If the notebook stops responding
• Press Ctrl+Alt+Del to end the application that is not responding.
• Reset the notebook—see “Resetting the Notebook” on page 11.
Power and Battery Problems
If the notebook turns off immediately after it turns on
• Battery power is probably extremely low. Plug in the AC adapter or insert a charged battery.
If the notebook keeps beeping
• The notebook beeps repeatedly when battery power is low (you can set this option in Power
Options in Control Panel). Save your work, turn off the notebook immediately, and insert a
charged battery or plug in the AC adapter.
If the battery doesn’t charge
• Make sure the AC adapter is fully plugged into 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 fully 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
• Try conserving power using any of the suggestions listed in the online Reference Guide.
• If you are running an application that has an automatic save feature (such as MS 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 can affect battery operating time.
• 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.
