Used arm band while running and I sweat some but never got drowned

Your problem requires disassembling your complete laptop to get to the processor chip. The factory forgot to remove a serial number label placed directly on the processor's heat sink so it causes the processor to get hot and shutdown to prevent damage. So you disassemble the laptop and remove the motherboard with attached heat sink on the bottom. Don't forget to use ESD tools and strap as you can destroy your motherboard. On a solid surface unscrew the 4 screws that hold the heat sink on the processor and carefully remove it. Clean off any old heat sink paste with a small cloth or paper towel. Rip slightly the serial number label and fold it so that none of it is on the heat sink but just the surrounding processor. Apply new Arctic Silver heat sink paste evenly to the processor pad. Re-attach the heat sink and assemble the laptop in reverse order of your disassembly. It will work fine after this repair. This repair was learned and used when my ownToshiba P775 had the same failure.

I know this problem has an old date stamp but the problem is the air doors that direct the air flow to the A/C evaporator or the heater core have lost the foam seal on their sides. This also happens on the defrost/ floor door. The job to have a auto shop reclaim all the freon in the A/C system and drain the coolant from the engine. Then disconnect the heater hoses and the A/C lines and Expansion valve from the evaporator. Then the time consuming fix this is to remove the dash and the heater/A/C unit and open it to reveal the doors. You can replace the seal by first cleaning off all that remains of the old seals and cutting out need seals from dinner plate protector sleeves found in moving departments of hardware stores. Cut it to the right size so the doors is sealed but not prevented from moving or sealing due to the new seal size. Using 3M spray tack, spray on one side of the new seal and after masking off the metal door, the one side of each door at a time with an even light coat. Let it dry 3 to 5...

You can go to a battery shop such as Batteries Plus. They can change the battery for you or you can do it yourself. It requires care in disassembly and reassembly but when shavers cost $100.+ dollars, it's worth it.

You will find a small locking lever under the hood and close to the rear edge of each headlight "frame" slide it to the opposite direction in it's "groove" and the headlight and the whole assemble will be able to slide out to change the bulb. Just reverse the procedure to lock them back in.

Go to ID Parts on the web and you can buy another one at a low cost...they only clip on
