My win XP laptop "locks" after timeout and must be logged back into

I am running Win XP Pro. If my laptop is idle for 10 minutes is automatically locks and I must log back into it. Where in the registry can I change this time? I work out in the field and there are numerous times every day when my computer is idle for 10 minutes or more. I have administrator rights to my laptop. Is this an easy fix?

 

I have found a temporary "fix" for this problem. Temporary because when I log back into the LAN network the policies will be reinstalled. The LAN administrators have apparently invoked a policy that has added a registry entry, under "policies" that forces a secure screensaver timeout. By doing so they have prevented me from changeing the time from the desktop. By deleting the screensaver policy entry from the registry I have temporarily regained desktop control of my screensaver options.

 

I believe that the option that you are seeking is in Control Panel - Power options. Open that and click on the Advanced tab. There is an option there that says "ask for password on Resume". If this option is checked, uncheck it and click on apply. This should stop your having to log in everytime your laptop hibernates or goes into its Green state. There are also options that you can set for how long until this action takes place. Hope this helps!
