If you have an I/O PC Card—that is, a PC Card having an external
connection, such as a modem or network card—remove it when you are
not using it. Some I/O cards use significant power, even while they’re
inactive.
To set time-outs
The BIOS Setup utility includes settings for automatic time-outs at specified
periods of inactivity. There are four different time-outs for different levels of
power and conservation.
1. From the Start menu, shut down then restart the OmniBook.
2. When you see the HP logo, press F2 to enter the BIOS Setup utility. Active
keys are described along the bottom of the screen. Help information for the
highlighted item appears in the right-hand sidebar in the display.
3. Select the Power menu.
4. Select Power Management Settings.
5. Press F10 to save and exit the BIOS Setup utility.
To get the most from your battery
The following are some further suggestions for the best management of your
OmniBook batteries.
•
Do not leave batteries unused for long periods of time. If you have more
than one, rotate them.
•
If you normally use ac power, make a practice of at least once a week using
the battery as your power source.
•
Unplug the ac adapter when the computer is not in use.
•
To preserve the life of your battery, be sure to charge the battery regularly.
•
For long-term storage, the battery must be charged at 20-50% to save
capacity loss by self-discharge and to avoid deterioration of battery
performance. In a discharged condition, the battery voltage decreases
faster. Storage in a 100% charged condition can cause higher self-discharge
and deterioration of discharge capacity—even after recharging—compared
to storage in a 20-50% charged condition.
To create a Hibernate partition
There must be a hibernation partition large enough to hold the contents of
memory on the hard disk before the OmniBook can hibernate. By default the
hibernation partition is large enough to hold the maximum amount of memory
