Power Management Features

Compaq Presario 3500 Series Personal Computers support the following power management
capabilities.
Sleep (standby)
Advanced Power Management
The following is a list of the power management features:
Power Status Lights. You can quickly tell the sleep condition of the system by glancing at
the Power Status Lights.
Automatic standby. In Windows 98 there are different Power Schemes under which the
system goes into Sleep mode automatically when it times out. The optional settings for
Windows 98 are Home/Office Desk, Portable/Laptop and Always On. The system
supports different levels of power management for varying patterns of computer usage.
Default and Adjustable timeout settings. The default setting for Sleep timeout is 30
minutes. The Sleep timeout value can be set in the Control Panel by clicking the Power
Management icon. At the Properties screen, click System Standby, Turn off Monitor,
and Turn off Hard Disk to set the length of time before the system goes to sleep.
Manual standby. To manually put your computer into sleep mode in the Windows 98
desktop, press the Instant On button (on the CPU) or the Sleep button (on the keyboard).
The power status light on the CPU will light to show that Sleep mode is activated.
Other manual standby options. Another way to put your computer into sleep mode
manually under Windows 98 is to select Start, then Shutdown. Select Standby from the list
of choices to put the system into Sleep mode. The system can then be turned off or left in
Sleep. When the Sleep button is pressed, the system reboots to the Windows 98 Desktop.
No audio CD interruption. When an audio CD is playing, the system will time out and enter
Sleep after 30 minutes or the set time, but audio play will not be interrupted. If either the
Instant On or the Sleep button is pressed, CD play is suspended and the unit enters Sleep.
CD play resumes on the next track when the system wakes.
Synchronized software and hardware volume control buttons.
