The small multi-bladed Black fan, sitting in the aluminum d-shaped shroud; is the Fan Assembly. The curved copper tube is the Cooling Tube. To the right of the D-shaped fan shroud, and copper Cooling Tube; is a rectangular finned Heatsink.
At the bottom of the Cooling Tube is the small metal plate, that sits on the Processor. It's mounting screws are circled in Red.
The Cooling Tube is a slightly flat copper tube, that is sealed on both ends; and filled with Nitrogen. Heat from the Processor is absorbed by this small metal plate, and then absorbed by the Cooling Tube.
The Cooling Tube transfers the heat up to the finned Heatsink. The Tall, Thin fins of the Heatsink absorb the heat, then radiate it away. Air flow from the Fan Assembly, helps carry heat away from the fins of the Heatsink.
Dust, dirt, lint, hair, food crumbs,....you name it, is drawn from underneath by the Fan Assembly. This clogs the fan blades, and fan shroud; and fins of the Heatsink. The cooling capacity drops tremendously.
See that thick 'dust bunnie' he removed from the finned Heatsink? You wouldn't believe the amount of 'Gunk' I have found in laptops! That video pales in compare!
(Tobacco smoke is a good one. Sticky gummy residue. So is carpet deodorizer. EVEN spider webs!)
The Processor, and graphics chipset; are the two hardware components that give out the most heat. Desktop or laptop.
When a Processor overheats it turns off. (BIOS turns if off) This is a fail safe feature built-in. Keeps the Processor from burning up.
2) The top of a Processor, and the top of a graphics chipset, (GPU), are not perfectly smooth. Neither is the bottom of the metal plates, that sit on them.
A magnified view would detail, "Hills, Valleys, and Pitholes'. When the two components are placed together (Processor/Cooling Tube plate; Graphics chipset/Cooling Tube plate), there are air pockets that are created.
Air is an Insulator, not a Conductor. Thermal Paste fills these imperfections, and is an Excellent conductor of heat.
Thermal paste dries up over time, and repeated heating. Looses it's thermal conductivity properties. (Thermal Pad is impregnated with Thermal Paste)
This is why is is conducive to THOROUGHLY clean the old Thermal Paste off, (and peel the Thermal Pad off), and replace the Thermal Paste. (And Thermal Pad on graphics chipset)
Hi, for what you say the fault generates the battery pack, you must remove the battery pack and work without it until you acquire the new one, the equipment operates on perfectly without battery packaging.
You are having the same charging issue that many other owners of this laptop are having. The power module where you plug in the AC adapter to the computer is defective. This is a known issue that Best Buy usually can't figure out. I sent mine back to Best Buy 4 times under warranty and they were unable to fix it.
If it's still under warranty tell them to replace that power plug circuit board or whatever it is and it will work fine. Mine has been working fine since Toshiba replaced that part 6 months ago.
