A) You may have your Power Settings set to turn off at a specified amount of time.

However I doubt this is the case.

Why?

Most of the time when this problem occurs with a laptop, it's because it is dirty inside.
If you have never had the laptop cleaned inside, and have had the laptop for some time; this is probably the problem.

The hardware components inside a laptop are cooled by air.
The Processor and graphics chipset, are the two hardware components that give off the most heat.

When a Processor overheats, (Exceeds it's thermal limit), it turns off.
(BIOS turns it off)
This is a fail safe feature built-in. Keeps the Processor from burning up. (Literally)

Let me show you an average laptop that is dirty inside, chandaravite,

http://www.youtube.com/watch?v=AkAeE5I5E_A

The example is using a model of Dell XPS 1710 laptop.
It's cooling system is similar to yours.

The copper colored flat curved tubes you see, are Cooling Tubes.
They are a slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.

Here is a better look,

http://www.txcesssurplus.com/servlet/the-4182/Dell-XPS-M170-M1710/Detail

This example is upside down, in relation to the example in the video.
The X shaped metal plate you see, with four mounting screws in it's corners, is the metal plate that sits on the Processor.

Heat is absorbed from the Processor by that metal plate. The Cooling Tube then absorbs heat from the plate.
Heat is then transferred up to the Heatsink, at the far right.

That black Heatsink is rectangular in shape, and composed of Tall, Thin fins.
The Heatsink absorbs heat from the Cooling Tube, then radiates the heat away with the Tall, Thin fins.

What you don't see attached in the video, is the Fan Assembly.
The Fan Assembly draws air from the bottom of the laptop, (With most models), then pushes air out through the fins of the Heatsink.
The air flow helps carry heat away from the fins of the Heatsink.

This particular laptop also has a separate Cooling Tube, for it's graphics chipset.

The bottom of a laptop is in VERY close proximity to the object it is resting on. Table, or hard surface.
(Not supposed to be on your lap, bed, couch, or directly on a carpet floor. BLOCKS the air intake OFF. Makes the laptop overheat)

The air intake of the laptop at the bottom, or at the side; will draw in a lot of 'Gunk'.
Gunk = Dirt, dust, hair, carpet deodorizer, lint, food crumbs,......you name it.

As you can see in the video, the 'Gunk' has formed a thick wad, and blocked off the fins of the Heatsink.
The cooling capacity has dropped Tremendously.

It is my humble opinion, that this may be what is going on with your laptop, also.

Do you wish to attempt cleaning? If so I need the model number, and see what information I can come up with.
Perhaps pictorial guide/s, and of course step by step info from me.

The model number is on the bottom of the laptop.
Post back in a Comment.

It could be also that the Thermal Paste has dried up.
This is used to help transfer heat from the top of the Processor, to the metal plate on the Cooling Tube.

Thermal Paste MUST always be used.

There also may be a Thermal Pad on top of the graphics chipset.
This is a semi-spongy type of material, that is impregnated with Thermal Paste.
A Thermal Pad CANNOT be reused.

It might be because your computer is overheating. Try installing Speed-Fan in order to check the temperature values your computer reaches. Also try cleaning the heatsink. you might want to consult the Hardware Maintance Manual of your computer.

SOURCE: Frequent interrruptions

Hi,

Initially, I would suspect the battery (even when plug to the AC). To confirm, pls try running without the battery and purely on AC adapter. Alternately, it could be a loose component internally such as the memory, LAN or WiFi card and in some models, video card. In my Toshiba, it turned out that the WiFi was consuming too much power that it discharges the battery rapidly and the charger was having a hard time coping up. My solution was to turnoff the built-in WiFi and install a D-Link USB.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

SOURCE: hi my laptop will turn

it may be shutting off due to thermal shutdown... basically the fan isn't keeping the cpu cool enough... check to make sure the fan is running and that the fan/cpu heatsink is clear of dust and dirt.

Dell 3537 laptop my vga adapter was changed but after that my laptop swithed off suddenly , sometimes it swithes on most of the time not switching on


Hello there
First things first:
1) perhaps its a bad VGA piece componet, or damage.
2) it will be connecting bad, on the mobo, or soldering
3) the swith for VGA and onboard its bad, or need to be check.
4) other than these, verify with your tech near you! for the VGA mode or inverter mode to VGA/Onboard .
Good Luck

Slow booting and sudden switch off


The reason may be one or more problems acting together. The problem nowadays is that it is very difficult and time consuming to monitor and take care of your Lenovo laptop. Even experienced users find it hard to perform such tasks on regular basis because you might need to prepare a huge amount of time and energy to deal with each issue separately.

If you want to fix the problems more efficiently, try the Lenovo speed up program. Regards!

The troubleshooter says that my wireless capability is turned off. It was working all last night and just randomly quit working.


You have to find the wireless switch because your swith is somehow turned off.
If that does not works go to
Device manager (Right click my computer go to properties, under properties go to hardware and then to device manager) and then uninstall the wireless drivers. Then restart the computer give your computer some time so that it can reinstall the drivers automatically.

Unfortunately it sounds like bad memory. Depending on your memory configuration you can try swithing out memory sticks. Check with your manufacture about memory configuation requirment before trying this. If you're unsure how to do this it's best to take it to someone who does know how.
