Managing Battery Power

Conserving Battery Power

 

To set power time-outs

 

Windows 95, 98, or NT

 

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.

 

 

Note

For Windows 98, power options you set in Power Management Control Panel override

 

corresponding settings in BIOS Setup.

 

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. (The pointing devices are not active in the

 

 

BIOS Setup utility.) Help information for the highlighted item appears in the right-

 

 

hand sidebar in the display.

 

3.

Select the Power menu.

 

4.

Select Power Management Mode. (Press the spacebar, F5, or F6 to pick an option

 

 

other than Disabled.)

 

 

Maximum Power Savings: The time-out settings are defined for best power savings

 

 

(relatively short time-outs).

 

 

Maximum Performance: The time-out settings are set for fast performance with

 

 

some power conservation (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

 

 

the main power modes, see “To start and stop the OmniBook” on page 20.

 

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 (default setting).

 

6.

Press F10 to save and exit the BIOS Setup utility.

 

Windows 2000

 

Power Options Properties includes settings for automatic time-outs at specified periods of

 

inactivity. Time-outs set in BIOS setup are ignored.

 

1.

From the Control Panel, open Power Options.

 

2.

Follow the instructions on the Power Schemes tab. We recommend that you avoid

 

 

setting the Hibernate time-outs to Never.
