Laptop overheats and shuts off because of back light

I have never heard of LED lighting or backlight of mouse/touch pad causing an overheat condition before. Are you sure this is the cause and its not the fact that its trying to charge the dead battery and the charge circuit is creating heat by trying to charge a bricked battery?

Try removing the battery and running laptop without battery but powered directly from wall adapter.

Would the hard drive happen to also be located in this area of the computer in which you have a hard drive that is roasting in its compartment. I have seen laptop hard drives fail and thy operate but roast in the compartment and cause a hot spot on the laptop. They generally fail pretty quickly too when they run this hot.

Thanks for responding:  battery can be replaced with a new one; no need to do so, because this is a stationary laptop.  I would like the back light to be off.  Backlight also displays the media functions of laptop above the keyboard.  Sure it looks great at night, and when it is on.  I would like to know how to control it, so I can turn it off or on when desired.  "Fn F5 or F9" does not do it.  Also, this laptop has two drive bays, I've moved the hd to the cooler side and all is fine, runs all day and night, I just want the light off.  Please help anybody.
