Power Management for Windows 98

Power Management Settings

Depending on your patterns of computer use, you can set different levels of power management. These different power management levels can be activated based on the amount of time passed since the last system activity. System activity examples include keyboard or mouse movement, CD or DVD playback (while under program control that monitors Sleep), and modem use.

You can select different conditions or power schemes through Power Management.The optional settings are Home/Office Desk, Portable/ Laptop, and Always On. From the default settings, you can change the following settings:

the System goes to Sleep (Standby) mode

the screen times out and goes blank

the hard drive spins down

Each of these system components goes to sleep after the selected or default periods of inactivity.

(The setting for hard drive must be less than, or equal to, the setting for System.)

IMPORTANT: If you're on a network, it's recommended that you set System Standby to Never.

There are five categories of power management settings under the Control Panel.

The default settings for each feature are listed in the following tables:
