I bought an HP N5270. Whenever I load an O/S everything works fine, but then after a little wjhile a few keys quit working.... The keys that stop working are: q, w, e, r, u, i, o, p and the up arrow. Like I said when I load it it works fine for a while and then after I have it off for a little while after the initial load-up and playing around... Anyone with ideas? A friend of mine that is great with desktops said to try and clean under those keys... The thing that stumps me is that they work fine and then they stop... <font color="blue"> </font color> I just started it up this morning and the keys are working now. So maybe this is a problem after it gets started and warms up..??..??
