I have a Dell XPS about 3 years old. Twice a year it would shut down and not boot for 3-7 days, then would work again for several months. I have gone through all of the procedures suggested in the forums. Now it will not boot unless I do this: I figured humidity must have something to do with the problem, so, I opened up the bottom, removed the ram, opened the cd drawer, removed the battery, and put a heat lamp (make sure it doesn't get too hot) and fan blowing on the upside down laptop. I have to do that for about 3 or 4 hours. Then, it will work just fine for about 5 or 6 hours, till it shuts off in the middle of your tediously composed work (of course the work has not been saved for awhile). If I only cook it for an hour or so, it will shut down after about an hour, but the longer I cook it, the longer it works.
Can anyone tell me what's happening here?
