Batteries and Power Management
Managing Power Consumption
Corporate Evaluator’s Guide 51
The computer can also enter Hibernate mode if battery power reaches a critically low
level. (See “To respond to a low-battery warning” on page 54.) If this happens, you will
find on resuming that all your data has been saved, but some functions may be disabled.
To resume normal operation, restore power by connecting an AC adapter or installing a
charged battery, then shut the computer off and restart it.
Changing timeout settings and creating power schemes
You can adjust the periods of non-use after which your computer automatically shuts
down components or enters a power-saving mode. You can also save these settings as a
power scheme.
1. Open Power Options in Control Panel:
•
Windows 2000: click Start, Settings, Control Panel, then double-click Power
Options.
•
Windows XP: click Start, Control Panel, Performance and Maintenance, Power
Options.
2. Click the Power Schemes tab, and enter the settings you want. If you don’t want a
particular timeout to occur, set the value to Never. See Windows Help for details.
If you want to save the settings as a power scheme, click Save As and enter a name
for the scheme.
CAUTION
Do not disable Hibernate support in the Power settings, or you will lose any
unsaved data if the computer’s battery runs down completely.
Managing CPU power
If your computer contains a multispeed processor with Intel SpeedStep Technology, the
taskbar in Windows 2000 contains an Intel SpeedStep Technology icon. This feature
enables the processor to automatically switch to lower, power-saving speeds or to higher-
performance speeds according to the workload.
You can customize SpeedStep to best suit your working environment.
•
Windows 2000: Double-click the Intel SpeedStep Technology icon in the taskbar,
then select the battery and AC options you want. The Max Battery option uses the
lowest processor speeds for maximum battery time. The Auto option uses medium
and high processor speeds.
