Hello Jones, and welcome to Seven Forums.
On some laptops you may need to press the FN key + Print Screen key for it to work for full screen screenshot, and ALT + FN + Print Screen to capture a screenshot of the active window.

Hope this helps,

Have you looked at using the Snipping tool in Windows 7 to capture the screen you want ?
