Thanks for that. I have the laptop running now and am logged into a
virtual console.

dmidecode details for my laptop:

BIOS Information
    Vendor: Dell Inc.
    Version: A21
    Release Date: 11/14/2013

System Information
    Manufacturer: Dell Inc.
    Product Name: Latitude E6420
    Version: 01

Base Board Information
    Manufacturer: Dell Inc.
    Product Name: 032T9K
    Version: A02

I might try downgrading the BIOS version to see if that helps. I don't
know that I've tried doing that with Dell's utility before, but I'll
give it a shot.

I setup a short loop to append the output of /usr/bin/sensors to a log
file and then call 'sync' just after.

This is the last entry just before the system shut down:

and this is the first entry just before I logged in:

Looks like the system is a bit warm, but not overly so? So far I've not
figured out how to check the fan speed. I'll keep looking.
