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. 

•  Press Ctrl+Alt+Del to end the application that is not responding. 
•  Reset the notebook—see “Resetting the Notebook” on page 11. 

•  Battery power is probably extremely low. Plug in the AC adapter or insert a charged battery. 

•  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. 

•  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. 

•  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.
