Specs: Windows 7
Windows 7 laptop, screen went blank after pressing ctrl + f12 and I cannot get it to come back on. I thought it dimmed the screen, but can't get the screen to come back on.

Let's try motherboard discharge - it's a long time since it paid off on here but it's easy to try:

Turn off computer and disconnect from domestic supply. Remove main battery if it's a laptop. Hold Power Off/On button down for about 30 seconds. Re-assemble and hope you are lucky.

Always pop back and let us know the outcome - thanks

Function keys vary from laptop to laptop. You didn't post the make/model of yours but Fn+F12 does nothing on my HP. Is there a 2ndary icon on the F12 key? On this Lenovo keyboard, F12 = fast forward.

"I thought it dimmed the screen". Maybe you dimmed it too much? Is there a 'brighten' key sequence?

You're lucky though. On some older laptops CTRL F12 opens an interdimensional vortex. Fortunately, newer ones have that function disabled.

(Oh Dave, stop that.)
