I was thinking the same - but started to despair

This test is outstanding for a moment where I have more free time to reproduce 
and log everything

I did something else yesterday evening before going to bed ~00:30
I closed the  notebook cover just so that it would switch off the LCD display
In the morning I opened up and found the notebook with blinking led lights 

http://www.dell.com/support/troubleshooting/us/en/19/KCS/KcsArticles/ArticleView?c=us&l=en&s=dhs&docid=DSN_DBECF64CFEDA449398CB9E859D4944A5

unfortunately I don't find the pattern in the link above
the left one was on and the other two were blinking

Arter shut down (keep power button pressed) and turning it on only the two 
leds (middle and right) were blinking, which according the link above means 

Configuring PCI bridges	Replacing the system board.

After waiting for about 1-2mins notebook starts normally - another link to 
heating issues.

At the moment I have to do pretty much at all levels, so I can not test any 
further.
This is just an update. I'll post again when more results are available.
I'm thinking to open up and inspect from inside - perhaps somewhere the 
cooling system is clogged or something.

regards
