Troubleshooting and Self-Repair Guide
Certain applications can cause excess CPU and power usage. (Users can get Intel Power Monitor
from www.intel.com and monitor CPU load.)
When playing DVD movies on battery power, use Power Options in Control Panel to select the
Portable/Laptop power scheme.
You may need to periodically train the battery and calibrate the battery gauge. To do this, restart
the notebook, press F6 when the HP logo appears, and follow the instructions that appear
onscreen. This process requires four to five hours to complete, and you cannot use the notebook
during this time.
Battery life depends on notebook model and usage, as well as battery type, training, and
calibration. The following are approximate lifespans by battery type:
8-cell Li-Ion: up to 3.5 hours.
6-cell Li-Ion: up to 2.5 hours.
8-cell NiMH: up to 2 hours.
Rechargeable batteries tend to degrade over time. 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.
If the Time Remaining for the battery is not correct
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 doesnt go on standby as expected
If you have a connection to another computer, the notebook wont 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 doesnt automatically hibernate as expected
Make sure hibernation 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 Hibernate timeouts for both AC power and
battery power are not set to Never.
