It means it's time to open up your' laptop and evict all the dust bunnies.  it's overheating on one desktop but not the other because one of your' desktops, as configured on your system is using the processor more.  this is how laptops die as most people just whine and complain as their' laptop gets slower and less stable.  

the first part to fail is often the hard drive.  hard drives can operate hot but it greatly shortens the drives lifetime.  on my desktop i try to keep my drives below 100deg F. they last forever practically then, where as around 120-130 you get fairly rapid failures.  

It's a major, major pain to work on most laptop hardware but you have to do it.  i have such a laptop that ran hot until the drive failed, so i got a nice laptop free that needs a new drive and cleaning, or possibly a new fan (they aren't running, either due to dust bunnies or failure".  it's a $300 laptop on ebay and i got it free because people ran it into the ground and they new i might be able to fix it.  if you do clean it out look for the repair manual so you can take it apart and get it back together correctly, and there are often good videos on youtube showing how for most models.
