Power And Battery Problems - HP Pavilion XZ335 Reference Manual

Troubleshooting and Maintenance
Getting Assistance for Your Notebook
• Restart the notebook.
• Some file browsers respond slowly while processing graphics or waiting for broken
network connections to time out.
• If the notebook's hard disk drive frequently runs (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.
• Press and hold the power button for at least four seconds to turn off and reset the
notebook. Then press the power button again to turn the notebook back on.
• If nothing happens, use a pen or straightened paper clip to press the reset switch on
the back of the notebook. Then press the power button to turn the notebook on.

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.
