Few things in life are as frustrating and infuriating as working ******* your laptop, only to see the screen go dark due to a sudden power loss. While there's a good chance your hard work and data is gone, the more concerning issue involves the cause of the sudden loss of laptop power. A suddenly dead laptop could indicate a more serious problem, or simply be due to a loose battery or power cord.

Overheating

If your laptop's fan was running hard and fast right before your laptop went dead, it's possible the machine shut itself down to avoid damage from overheating. The internal electronic components of a laptop generate heat when the computer is turned on, and this heat must vent to avoid causing damage to the machine. If the air vents are clogged or blocked and the heat inside cannot dissipate, the laptop will power down without warning to prevent possible damage. To avoid this problem, ensure that your laptop's fans and air vents are clean and clear, or use a laptop cooling stand to help vent the heat.
Battery Issues

Laptop batteries are not exempt from malfunctions, and a sudden power loss may point to a problematic battery. A loose connection may cause a surprise laptop death, as can dirty connectors. Like most other battery types, laptop batteries are not immortal and eventually lose the ability to hold a charge for long. Some laptops have sensors and circuitry to monitor the battery, and will cut power to and from it should it become too hot or exhibit too high a current. Try cleaning the connectors and reseating the battery properly to fix the problem. In the event of a loose connection, a repair technician may be your best course. For malfunctioning batteries, a new replacement battery may be the best way to prevent future power failures.
Electrical Problems

If you were using your AC adapter for power right before your laptop powered off, there may be an electrical problem somewhere along the line. The outlet you were plugged into may have short circuited, or the adapter itself may have overloaded. The connector on the back of your laptop may be loose, preventing proper connection of the adapter. A short circuit within the laptop itself may have occurred, preventing either the battery or adapter from providing power to the rest of the electronics. Work backwards to find the source of the power supply problem. Try a different electronic device in the outlet, and insert the adapter itself into a different outlet. Reinsert the various cord ends into the adapter and laptop to ensure a tight connection. If a short circuit seems the likely cause, seek the help of a professional technician for repair.
Troubleshooting

Try to ascertain what occurred right before the power loss. A physical move of the laptop may have loosened the battery or jostled the adapter cord loose. Try removing and then reseating the battery and tightening the adapter cord. A loud fan noise may indicate that the machine was on the verge of overheating. Let the machine cool completely before attempting to reboot. An unusual noise emanating from within your laptop may indicate a short circuit. A beverage spill can cause the death of an laptop if not attended to quickly, causing short circuits and power failure.
Precautions

Observe standard safety procedures when dealing with electricity, and never disassemble or examine an outlet or your laptop without disconnecting all power first. If delving into your laptop to check for short circuits and loose connections, work in a clean, open area to avoid introducing any new contaminants to your laptop's vulnerable interior.

Definitely overheating, and I would say especially if its a gaming laptop of the video chip, try taking a vacuum cleaner (pipe type) to the vents as they have probably built up a lot of dust and fluff over the years, if that does not sort it out, I would take it to a repairer, its a simple job of cleaning the insides, but taking a laptop to bits is thwart with danger as there are thin ribbon cables and connectors that break easily when you are trying to separate some of the click in parts, without experience.

Hope this helps and fixes your problem. Remember to do this every few months. I do it every 6 to keep it nice and clean. After all dust has static electricity and that's not something I want inside my computers.

replace the switch and also check the connector to the switch, this older fords had problems with the connector melting due to the switch shorting and overheating, good luck.

Laptop overheating has become a more common problem in recent years as both the CPU chips and the video chips in laptop computers have become more densely packed with transistors, all of which generate heat. With both CPUs and graphic systems generating more heat, laptops can overheat if they are not properly designed or if ventilation and cooling is interfered with. The problem is compounded when manufacturers put desktop components in mobile systems, or when laptop design does not properly provide for laptop cooling under foreseeable normal use of the systems.
Laptop overheating most commonly signals itself by sudden, otherwise unexplained shutdown of an operating computer. If your laptop computer suddenly shuts down for no known reason, there is a high likelihood that the fail safe software in the computer is shutting it down when the computer temperature gets too high. Other signs of overheating notebook computers include constant or excessive fan operation, unexplained memory or operation errors, and inexplicable “blue screens of death.”
The problem often arises when you are using your computer intensively in ways that keep the CPU operating at high capacity and the hard drive and video systems busy as well. Gaming often leads to laptop overheating. Virus scans, compiling software and similar intensive tasks can also bring on the problem. The problem also, not surprisingly, sometimes occurs when the temperatures are high in the setting where the laptop is being used.
The consequences of overheating laptops can be quite serious. Your computer can be damaged, and may end up requiring expensive replacement of major system components, such as motherboards or graphic cards. In addition, medical researchers have reported health issues ranging from sterility to burned genitalia related to use of overheated laptops by fully clothed users.
If you have an overheating laptop and your computer is still under warranty, you should promptly report the problem to the manufacturer and seek their help. Because many manufacturers seem to engage in denial rather than cures with regard to this particular problem, you should also read the information on laptop overheating on this and related sites so you can better understand the causes, the consequences and the possible cures for notebook computer overheating.

Here is the to see some tips on why your laptop is overheating.

Good luck!

I think you have answered this issue yourself, I sugest that you obtain two items, a cooler pad, and a usb powered mini fan for carrying around

no this happened with my friends hp laptop then he updated his bios firmware over the internet and now his laptop does not gets off when hot

It sounds like an overheating problem. When it is booted, does it run ok other than just being slow? Check your cooling fan and make sure it is running and not stopped up. That is a number one symtom of overheating is freezing and rebooting by itself. There is a free program called "Motherboard Monitor 5" that will monitor the temp for you and set off an alarm when it is getting to hot. Check that problem first. Hopes this helps!
