Check the inlets and outlets. The ones on laptops tend to get congested with
dust.

All the filters have been cleaned.* When the tech replaced the motherboard he had to remove the heat sync.* When he did this a piece of copper or copper alloy fell off it's about an inch square.** The tech said that it was not necessary and did not replace it (fortunately I still have it).* My suspicion is that this component is needed.
I was able to get Windows 7 to power off as well.* Linux does something during boot that causes some device to overheat resulting in the system powering off while Windows will boot up just fine.* It's only when I try to refresh the Windows Experience Index (Control Panel -> Performance Information and Tools) that Windows exhibits the same power off problem that I see in Linux.

I talked with the Dell tech and he told me that in fact the heat sink he did not put back was important,* The part has been ordered and hopefully it will fix the problem.
I still don't know what Linux is doing during boot that causes it to power the system off while Windows boots just fine.

I hope that you have some sort of record that the Dell tech told you
that the heat sink wasn't important. If he tries to charge you anything
for the repairs, you should take this to Dell, and that record will keep
it from being simply your word against his.

Do you use an encrypted drive? That's one thing that would require
intensive CPU to decrypt, and one thing that Windows probably isn't
doing.
On my my older Fedora release, I do see something similar. When I boot
up, my laptop CPU rapidly gets *very* hot while just sitting there
waiting for me to enter the password to decrypt the drive. Dunno why
it's grinding its gears before it's actually doing the work.
No, it's not just the fan running at full speed, uncontrolled, it is
venting out hot air. Usually, there's just a slightly warm breeze being
vented.
Don't send private replies to my address, the mailbox is ignored. I
read messages from the public lists.

I don't have an encrypted drive.* But something is causing the fan to speed up right before it powers off.

Fortunately this is all covered under warranty so nothing is coming out of my pocket.* I hate to have to pay for all this work.

No $$$ out of pocket but what about your wasted time?* Dell should
be glad you don't charge them for that.
