Have you checked to make sure the settings for Standby are still correct? Open the Control Panel, then the "Display" icon, then click on the "ScreenSaver" tab, then click on the "Power" button. Is the "Standby" selection set to a specific time or does it say "Never". Either way, try changing the time period designated, then click on Apply, then OK.
Have you changed the BIOS settings recently which may have disable the power options for Standby?
Hope this helps.
Is there someway that I can make it go into standby once again? I have Windows XP. I am not sure what other information you would need. So if you need something specific just let me know and I will try to find it for you.
Thanks so much
