To Get The Most From Your Batteries; To Change A Time-Out Setting - HP OmniBook 2100 User Manual

If you work with an application that uses the serial port or an I/O PC Card, exit
the application when you're done using it.
Install a secondary battery in the plug-in module bay to double the operating
time.

To get the most from your batteries

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 a battery, be sure to charge the battery regularly.
For long-term storage, the battery must be charged at 20–50% to minimize
capacity loss by self-discharge and to avoid deterioration of battery
performance.

To change a time-out setting

The BIOS Setup utility includes settings for automatic time-outs after specified
periods of inactivity. (This program is described fully in the Reference Guide that
came with your OmniBook.) When enabled, these settings save power. There are
four different time-outs, inducing different levels of power shut-down 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.
Pointing devices do not work in the BIOS Setup utility.
Active keys are described along the bottom of the window.
Help information for the highlighted item appears on the right side of the
window.
3. Select the Power menu.
4. Select Power Management Mode, then select an option other than Disabled:
Max. Power Savings: The time-out settings are predefined for best power
savings (using relatively short time-outs).
Max. Performance: The time-out settings are set for fast performance with
some power conservation (using relatively long time-outs).
Customized: You determine each setting for Smart CPU Mode, Standby
Time-out, Suspend Time-out, Hibernate Time-out, and Hard Disk Time-out.
For definitions of these power modes, see
5. Optional. Choose a setting for Time-out on AC. If you want the time-outs to
occur even when the OmniBook is connected to ac power, choose Enabled. To
prevent time-outs while the OmniBook is plugged in, choose Disabled.
