touch screen
An external monitor - will prove that the device is actually working (and it's just the display that's at fault).
It will be blank..nothing is saved to your moniter.
An LCD monitor can go blank for several reasons. They include a loose cable, a weak input signal, an issue with the video card or a driver needs to be updated.

Try this, find another computer and hook the monitor onto it, see if it's blank then.What to do:1) If the monitor is not blank then your other computer probably needs a video driver (need help on this? ask another question and I will try to answer you) ORYour graphics card might be burnt out and you might need to purchase a new one.2) If the monitor is still blank, try to obtain another vga cable(the blue plug thing), if still blank go buy a new monitor**Hope this helps would be able to help you better if i know any previous symptoms or was there next to your computer. Good luck!
This could be due to a number of reasons. 1. Your power supply became unplugged or battery life died. Check to make sure it is plugged into an outlet and the battery still has about 20% left. 2. DVI or VGI cable came loose from the monitor. This would stop the monitor's functioning. 3. You bumped one of the F keys on the top of your keyboard that may of disabled your display.
That would be your screensever.
