You probably have noticed that when you press print screen on hp or dell or some other notebook computer, it does not take the screen shot of your desktop.
Even shift + print screen don’t seem to work. So how to make it work? well her it is!
On laptops like hp notebooks, you need to function (fn) key to make these functions including print screen to work instead of directly pressing them or using shift key with them.
So to take the screen shot of your desktop, simply press fn + print screen key on your hp/dell notebook and paste the image in the mspaint or any other image editing utitility!
For windows on macbook you need to use fn + shift + f11 to take the screen shot.
