Power Management Features

Compaq Presario 2250, 2510, 2410 ES and 4240 ES Series Personal Computers support the following power management capabilities.

  • Sleep (standby)

  • APM 1.2

Select the power management features for your operating system: Windows 95 or Windows 98.

 


Windows 95

  • The system enters Sleep when Windows Suspend is selected, when the Sleep button is pressed, or when the system times out.

  • The system supports the Medium power setting, which allows the unit to enter Sleep mode without losing its network connection.

  • In the Windows 95 desktop, select Start, then Shutdown 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 95 Desktop.

  • The default setting for Sleep timeout is 30 minutes. The Sleep timeout value is set in the BIOS Setup.

  • The modem wakes up the system on incoming calls when configured to expect a call.

  • When an audio CD is playing, the system will time out and enter Sleep after 30 minutes, but audio play will not be interrupted. If the Sleep button is pressed or if Suspend is selected, CD play is suspended and the unit enters Sleep. CD play resumes on the next track when the system wakes.

  • The software and hardware volume control buttons are synchronized.

States of Power Management

Power management can be defined by three distinct power states in which the computer operates: On, Off, and Sleep. The following table describes the energy states and lists the power consumption of each state:

Windows 98

 

  • 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 use.
  • 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 on the Power Management icon. At the Properties screen, click, in turn, on System Standby, Turn off Monitor, and Turn off Hard Disk to set the 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 (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.
