After a Microsoft Windows XP Media Center Edition 2005-based computer enters Away mode, nothing happens when you press the Sleep button on the USB keyboard. Additionally, the system idle timer is not reset. Therefore, the computer may eventually enter the S1 or S3 state of Advanced Configuration and Power Interface (ACPI) standby. (The computer enters standby after the interval that you specified on the Power Schemes tab of the Power Options dialog box.) The computer may enter standby even though you have pressed the Sleep button while the system is in Away mode.
When the computer is in Away mode, input from devices such as keyboards, mouse devices, or the remote is filtered to make sure that errant keystrokes are not processed. For example, when you press the Sleep button while the computer is in Away mode, the following events occur:
- The Away mode driver captures the Sleep command from the USB keyboard. Therefore, the computer does not immediately resume from Away mode or enter standby.
- Because the Away mode driver captures the Sleep command, the system idle timer does not receive the command from the keyboard.
- Because the system idle timer does not receive the Sleep command, the system idle timer is not reset.
- Because the system idle timer is not reset, the computer may eventually enter the S1 or S3 state of ACPI standby.
- Paging operations
- When Windows Update examines the system state
- Event logging
- Network detection, such as Dynamic Host Configuration Protocol (DHCP) or Automatic Private IP Addressing (APIPA)
- Third-party services, such as an antivirus program
- Scheduled tasks
Away mode is not installed as part of Update Rollup 2 for Windows XP Media Center Edition 2005. This feature is available only if the Away mode component was preinstalled by an OEM or by a system builder on a new Media Center computer that supports this technology.
