HP Pavilion XZ335 Reference Manual page 115

• 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 "To get the most from
your batteries" on page 51.
• 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.
If the Time Remaining for the battery seems incorrect
• The Time Remaining is an estimate based on the rate at which the notebook is using
power at that instant. So, if you check the Time Remaining while the notebook is
using a good deal of power (such as when reading from a CD or DVD), the value will
likely show less time remaining than you really have, since you will probably later
switch to tasks that require less power.
If the notebook doesn't go on standby as expected
• If you have a connection to another computer, the notebook won't go on standby if
the connection is active.
• If the notebook is performing an operation, it normally waits for the operation to
finish before going on standby.
If the notebook doesn't automatically hibernate as expected
• Make sure hibernate support is enabled: click Start, Control Panel, Performance and
Maintenance, Power Options, then click the Hibernate tab.
Also, check the Power Schemes tab. Make sure the hibernation timeouts for AC
power and battery power are not set to Never.
