Right click any blank space on your desktop.
Select Properties then under the Screen Saver tab click the Power button.
Change the settings as you wish.I suggest you use "Always on" for Power schemes, and set everything else to Never.
Hi. just bought a new Dell inspiron 1000, it runs off of XP, I was just wondering how to turn off sleep mode. Because whenever i close the screen it goes into it, and it's really annoying because it disconects me from the internet?
