You're right about the Dell site, Mike, and bearing in mind your loose lid; found this little tinker which may be of use to other people.
This may seem odd, but i had a problem wherein the laptop intermittantly shut down for no reason. Finally one day it shut down and wouldn't power back up at all.
Turns out it was the little soft rubber nipple near the hinge. This actually goes to a switch that shuts down the machine when you close the cover (screen). It got pushed down below the plastic in the little hole where it resides. It held the switch down all the time. I got some very small tweezers and phished it out of there. Made sure it was not ripped and it is working fine. I will be keeping an eye on it,though.
And the classic;
*Take out the battery,
*Remove main supply,
*Hold power button down for 30 secs,
*Put only power supply in, do not put battery in
*Turn laptop on
*Put the battery in.
