Turned on one of our laptops last night.  This is one the kids use for school work.  It's a toshiba.  I can get more specific if I need to.
The kids are, well, kids and are not always SUPER careful.  I found two laptops sort of down the side of a couch cushion last night.  :/
Anyway... I turned the toshiba on and twice a message popped up saying there was something wrong with the "cooling system" and I should shut it down as soon as possible.
I lifted it up in the air and held it in different positions and the fan did eventually turn on.  Didn't end up with any overheating problems and after that happening twice within the first few minutes... I got it rested in a good position or something and I used it for a couple hours with no issues.
We're going to turn it on in just a bit so they can get started with their school work...  but if that keeps happening, I'd say something is wrong with the hardware.
The question I'll have to troubleshoot is WHAT.
I've had this machine open a few times so that isn't a problem.  if a wire is loose(which I doubt) that would be a simple thing to deal with. 
But there's a good chance that whatever is not working might not be obviously visible...  Meaning, I might not be able to just look at it and see the problem. 
Then I have to wonder and worry... is it simply the fan, a connection, or... something on the motherboard?  :/
If those rugged laptops weren't so expensive I'd buy a couple... even for my wife.  They're just not built to be used so carelessly and let's face it... people are careless...  My kids are more gentle than some though.  I've worked on some for other people that were in HORRIBLE shape from mishandling. 
eh...

ppl might disagree with this, but i prefer to "poke the bear" nd by that i mean try nd provoke the issue. not like putting it under a blanket or nothin, but u mentioned that u shook it a bit, mabye see if the problem happens again. then if it occurs again, there r quite easy ways of diagnosing possible things. might sound stupid... just my .02.... atleast then u can confront the issue, instead of praying it goes away.

You say You had it open a few times. Is it possible that there could be some dust built up on the heat sink assembly and that some of it had shifted into the cooling fan, Keeping it from running?

 

I have seen that happen on several different laptops in the past.

 

If You can see the cooling fan does it spin freely? Be very careful the fan blades are very easy to break.

 

Good Luck
