display goes to black screen

  Fungus 19:10 26 Feb 04

we have a toshiba satelite 1800-400 running windows me.
recently when being used the screen goes from windows display to a blank/black screen. when the small pin is pressed (at the top r/h side above keyboard panel) the display resumes to normal. all hibernate and sleep times are on max.
the problem gets worse if the a/c is plugged in, then you have to keep pressing the small button to resume normal display, but imeadiately it wil go blank again. it has new battery.
is this software or hardware?

sounds like it's a bad connection on the hinge pin that you are pressing, this is a dismantle job. it works on the same principal as a car door switch for internal lighting

but why would it be worse when the a/c cord is plugged in?

No idea but the above is the problem the little pin is the lid switch that you are pressing and it means the contacts are dirty or burnt
