*LAPTOP* is Randomly shutting off http://www.bleepingcomputer.com/forums/style_emoticons/default/wacko.gif

Hi,
My Laptop just started shutting down.
This started maybe 4 days ago. I would be using the Laptop and it shuts down. I turn it back on and it may stay on for hours.....then shut down again. No blue screen..

I also have (2) desktop windows pc's and in the months ago, the same thing was happening to these. It turned out to be the Power Supply Units, I, being somewhat a novice, removed and replaced them with new ones. Luckily that corrected the problem for both desktops.

I will assume that the same thing is happening to my 4 yr old HP laptop.
I was wondering what anyone can tell me about opening up the laptop case and searching for the PSU. Is replacing the PSU gonna be a hard thing to do on a laptop?


PS. A portion of my screen is broken in a hinge area on the bottom corner...Could this contribute to the turning on and off problem??? Could this contribute to my wireless connection being quirky at times? I may have to post a new topic for this problem in a new thread.
Thanks in advance
WINDOWS XP home edition sp2

The way you describe it, it sounds like it might be overheating
Sometime a can of compressed air will work
Direct the nozzle into the vent holes on the side/back and the bottom

A portion of my screen is broken in a hinge area on the bottom corner.

This is where some manufacturers locate the lid switch
If the screen is making contact when it shouldn't, that is another possibility
