Ok folks, I rarely log in to ask questions so forgive me if I'm in the wrong category. Ok, the pc is a laptop (HP Elitebook 8460p, i5-2520m CPU 2.50GHz, 4GB RAM, Crucial 240GB SSD) running Win 7 Pro 64.
Now I've scoured the net and can't find a single post with my unique problem. My laptop seems to work great in every way untill I start using it on battery power. The bat charges fine and holds a good charge. It'll runn for hours on that charge too so I don't see that as a sourse of the isue. What happens is, while using it (not plugged in), I will go to move the curser and that triggers the screen to go crazy fuzzy looking. This is "not" the blury display that so many are having with Win 8.1. I want to say more of a static like fuzzy, fine zigzag fuzzy, though I can't call it pixelating either because it doesn't break up into squares in a blender. It still seems to be functional in that I can still move the curser and close out, however it's too rough to actualy be useable. For example I try to close any extra windows to see it helps limit the occurance and it takes at least 3 or 4 clicks to find and hit the "X" to close a window.
I say "limit the occurance" because it doesn't do it every time I touch the mousepad and the display snaps out of it after I leave it alone for a few seconds. I've had it happen just every few minutes, then on other occasions it was fine for a short while then once it starts, it will do it nearly every time I attempt to move the curser. This renders it pretty useless if not plugged in. I wondered if it was getting hot so I openned and blew it out but the only dust was a tiny bit collected on the fan blades themselves.
Just a quick history on the machine: Bought it used from one of these on-line busineses that get them turned in from wherever. They check that they basicly work, pull the HDD and sell it like that. I bought SSD, charger, loaded OS, drivers from HP and walah! $210 for a great laptop, fast and all the features I need. Except this one little/big problem. Can anyone help me? I don't what else to try.
