I have a problem in XPE with the Power Scheme Setting of
Monitor. The XPE is customized to run in command shell
only. It turns off all monitors (There are three monitors
connected to the PC, using Matrox G450 dual head display
card) after the system has been idle for a specified
period of time, about 20 min. I know that this is related
to the power scheme setting of monitor.
For Windows XP, choosing "Presentation" as the Power
Scheme can keep both monitors, hard disks always turn on
and system never goes into standby mode. I thought the
same principle should be working to XPE and such setting
can be found in the component "Standard PC" in the Target
Analyzer. After the XPE is deployed, we checked the value
of registry key [HKEY_USERS\.DEFAULT\Control
Panel\PowerCfg\CurrentPowerPolicy] is also 2, which means
the current power scheme used in XPE is "Presentation".
Also, both APM and ACPI functions are enabled in the BIOS.
However, the monitor still turns off after the system has
been idle for about 20 min.
Does anyone get any idea to keep the monitor on
permanently?
