Having problems with your Toshiba Satellite L300D-ST3501 Notebook ?

Black Screen I was attched to a projector and pressed F4 and l think F5 the picture went to the screen but my screen went blank, and l have not been able since to get anything on the screen when l start it up.


Answers :

You pressed the FN key and whicever special function key controls the video display.
There normally are 3 settings. They are (not necessarily in this order) 1) put the video on the external monitor, 2) put the video on the computer's monitor, and 3) put the display on both monitors.
If you have no display showing, try pressing the key combinations several times. If you still see nothing, try connecting the computer to an external monitor to be sure it works.
Have you tried cycling all the way through the options with the F4? Most laptops toggle in a manner similar to: 1) Laptop only, 2) External display only, 3) Both displays, 4) Back to Laptop only (cycle repeats).
