Prevent laptop from going to sleep when I close the lid, but only if I'm connected to an external display

When I'm connected to an external display, I would like to close the laptop without it going to sleep. When I'm not connected to an external display, I would like to have closing the lid put the laptop to sleep. I know I can achieve this by manually switching the power settings, but I'd like something automatic. I'm running Windows 7 (Home Premium 64bit) on an HP Pavilion dm3-1030us. Thanks.

Write a script or service, that detects if an external display is connected. If it is, have the script/service turn on sleep setting. If it is not, have the script/service turn off sleep setting again.

Other than that I am not aware of a solution.

2I've already checked there. It only differentiates between plugged in and on battery. There is nothing about being connected to an external display. – blauser – 2010-10-08T15:27:27.663
