If you are using Vista, you can use the Snipping Tool under Accessories in the Start menu.
If you have XP, you can use the Prnt Scrn button and then go to Paint or another photo editing program and paste it from your clipboard and then save it as a .jpg, .gif, or whatever format you want.
Thanks Jakpro, that tidbit solved a problem I was having on a project involving Google maps.
I love this board!
There are many ways to take a screenshot on a laptop, while as to where can you find it, it depends on which method you employ. For example, you can use “PrtSc” key to snapshot the whole screen or press “Alt+PrtSc” to screenshot an active window. After that, go to Paint (Start-Accessories-Paint), press Ctrl+V to paste the image on the blank board. Click the save button on the top bar, and choose a folder to preserve the image. Then you can find your image in that folder later.
Since you haven't mention which operating system you are now using on your laptop, you can find solutions here, it provides multiple methods for you to take a screenshot on Windows and Mac laptop. http://screenshot.net/howto-take-laptop-screenshot.html
