Windows XP goes into standby when no one is logged in

q:  Issue reported that a Windows XP Desktop continues to run while a user is logged in, active or not.  But if they system is rebooted, or the user logs out, it goes into standby after 15min.

a:  This is an issue of Power registry settings associated with the default user

  • Open the Registry (regedit)
  • navigate to HKEY_USERS\.DEFAULT\Control Panel\PowerCfg
  • Notice the value of CurrentPowerPolicy = 1
  • Expand PowerCfg\PowerPolicies and select 1 - notice the name is "Portable/Laptop"
  • Navigate to PowerCfg\PowerPolicies and select 3 - notice the name is "Always On"
  • Navigate back up to PowerCfg and change CurrentPowerPolicy from 1 to 3 
  • Reboot
