suddenly my laptop screen has gone blank, though i could hear the windows program opening up. i connected to an external monitor and saw the text and images correctly and from my laptop typing screen. i could use the laptop keyboard again efficiently.I went to appearances and changing the settings did not work.i enlisted the support of an I.T. specialist but he gave up.Also sometimes the resolution goes to its 600x ? settings and will not allow a change but then it does after rebooting.Is this a hardware or software problem ?

If you can use an external monitor, then it sounds like your LCD Screen has gone Kaput.

What type of laptop do you have? (Make, model).

If you are able to load to an external monitor the first thing I would suggest is attempting to reload the video drivers. If they will not reload then I would have to say that you more than likely have lost the LCD controller on the main board. Unfourtunantly that is a rather expensive fix....you have to replace the whole main board on the laptop normally. That goes double if you have name brand that you bought "off the
shelf" (did not customize). Sorry I could not give you better advice....:sigh:
