My Inspiron 8600 had a hard drive failure. Dell sent me a new machine- a 6400, not bad: bigger drive, faster processor, and a few other nicer gadgets that I didn't have on the first machine.
Problem:
When I move my cursor around it leaves little squared- edge "holes" in whatever graphic is on the screen. It can leave this "pixel trash" either directly on the desktop or on an open window. If it's on a window, I can grab the handle on the window and move it around with the window: it stays in the exact same location on the window without respect to it's location on the monitor. If I move the cursor back over the messy spot it will hardly ever refresh the area, instead leaving it alone and occasionally making it bigger. It does seem to happen more frequently when on battery power.
Dells' solution:
they had me run my diagnostics (already had and it showed no problem with motherboard, memory, LCD, video card, nada). Then had me reformat, didn't solve the problem. Then sent out a tech with a new LCD, again didn't solve the problem. Finally agreed to send me a new machine.
I just received my replacement replacement machine and it has the exact same problem. Any ideas?
