SOURCE: Windows(Vista) shuts down without notice

Most likely this is a overheating issue. previous suggestions of getting space between the laptop bottom and the surface it rests on will help but investment in a laptop cooler will be even better. Most laptops have cooling issues. You will notice hot areas near the Alt key and upper left corner of touch pad. Also heat directly under that same location. Warmer to hot air will blow on the fan vent left of the esc key.

Another clue to be sure this is heating problem is does it happen right away or after being on a little while? the long it is on the worse problems get.

Sometimes overheating can be casued by operation in a dirty air environment that builds up dust on the exhaust fan or the vents under the computer. all of these areas need to be clear or airflow to get proper cooling. Never use a vaccume cleaner on these areas while its on and best when the battery is removed as well. static electricity builds on vaccume cleaner hoses and could potentially damage your computer. Clean sufaces with a moist not wet soft cloth not cleaning solutions or achohol as they will damage the suraces of the screen or computer keys and coverings.
Many years as an engineer working on electronic components has taught me to follow these simple guildlines to get a long life from your equipment. The more heat and the longer exposed to heat the shorter the life of components.

Sounds like there is dust where the cpu fan is and its blocking the ventilation path in the laptop. If you can take apart the laptop to expose the fan, I would make sure the fan is free of debris. Clogged CPU fans will cause the laptop to overheat cause the air has nowhere to go.

If you do that and the laptop is still overheating then the motherboard is going bad unless your not using the correct charger for it. If you use a charger that puts out more voltage then whats needed then that could cause the laptop to overheat so you might need a new charger.

SOURCE: Aspire 5535 appears to be over heating

There is a small cooling fan in the base of this model. If you look closely at the rectangular vent slots (in the rear left from the front if I remember right) you will see a round area. That's the fan. You should be able to feel some hot air being forced out of the unit there long before it shuts down and if you put your ear close to it you can usually hear the fan if it is working. It is common for these to require replacement. If you search the web using your favorite search engine and look for Aspire 5500 you will probably find a listing for a supplier and a price of several tens of dollars. the fan is equipped with a connector and does not require soldering to replace. Any Acer service depot could also diagnose and replace it if necessary for you, it is a common repair.

SOURCE: Over heating laptop shuts down

What is happening is that the processors thermal shut down safety is activating. Cleaning the fan and vents was a good first step but there is something else that needs to be done in order to make sure the processor is not overheating. First, make sure the fan is running at all times. If it is for the duration you're observing and the laptop is still shutting off, then the problem may lie at the heatsink-processor interface. This is where the heatsink sints on the processor face and has a thin layer of thermal paste between the two. If there has been a breakdown in the thermal paste and it is not doing its job, then you can have a thermal shutdown.
Now, the nice thing about your system is that you can clean the heatsink fan and grills just by taking off the bottom panel. Unplug the wiring harness for the fan and unscrew the heatsink off the processor slot. Clean the surfaces well with alchohol and let dry, then apply a very thin layer of thermal paste to the heatsink, screw it back down on the processor. Now leave this panel access door off while you power the system back up, that way you can easily observe what is going on in this area. Make sure to use good clean compressed air from an pffice supply chain to blow out all vent and compartments. Do not use the sir while the system is powered on just in case some condensation escapes from the can.. Good luck, below is the link to the service manual for that laptop. An illustrated guide of the disassembly starts on page 70.

Laptop shuts off afer 5 minutes


Sounds like your laptop might be overheating. Does it reboot successfully immediately after is shuts down after 5 minutes or does it have to sit awhile before it reboots successfully?

If you can't boot it right back up after it shuts down, then it is definitely running hot and will only boot back up successfully after it sits awhile to cool off.

Things that cause it to run hot:
1) Dust... Dust clogged in the vents, fans and around the cpu and heat sink.
2) A Fan is not working
3) The Thermal Paste around the CPU and Heat Sink has dried up or is too thin to keep the unit cool.

For the best results you'll have to take the laptop apart to remedy the situation especially if you need to get to the Fan, CPU or Heat Sink.

You can try a can of compressed air and blow out the vents and fan area, that might work for a while but you'll be blowing the dust in. It's best to take it apart and blow the dust out.

The Importance Of Cleaning Your Computers or Laptop


One of the most important jobs that you will do is cleaning out the dust in your computer. A lot of us just take it for granted, put it off until something happens to our machines. Dust is a killer of CPU's and devices as well as motherboards. I mention to all of my clients and friends to dust there machines regularly. Keep animals away from them because of the animal hair, if you machine is on the floor get it off the floor. Raise it up a few inches off the floor to keep animals from urinating on them or spraying them. The CPU will get really hot if cooling fans are not working properly change them out if making grinding noise. Dust the blocks completely under the CPU fan and fix with Heat Sync Paste every 6 months or so.
This will keep your computer safe from fires shorts and burnt boards or devices. Just a simple vacuum will work that blows air or cans of air work as well also. I use a vacuum that blows air. Place outside and do this blow your computer out really good. Take a light brush or a soft brush to scrub out the parts being gentle as to not hit parts and break them with the brush. Takes about 5 minutes or less of your time. Compared to a new computer or the expense for parts, well think about it.
You may think by blowing out the laptop you have got it all. Not true laptops take a bit more time and should really be broken down to get to the copper tubing vents these are always getting clogged up. Every wonder why your machine shuts down a lot that my be the reason. Thermo shut keeps your laptop from overheating before the melt down. This can damage on board devices as well as the video card chips. Weakens the solder points so that they will eventually crack and short. Ever wonder why video gets choppy when machine is getting to hot.
Heat like anything else is the number one killer of any machine. So if we tend to take care of that we will never have any breakdowns. Other than basic parts wearing out. That is about all we will deal with if you keep your computer dusted and clean of debris. Just a little advice. John A. Crowder

What might be the cause when machine gets hot when shut down


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

My Sony Vaio VGN-CR320E turns itself off all the time. I have already formatted it, but the problem continues... What can I do?


IS it getting hot. Check the fans. It'll shut down if the fans aren't running and everything gets to hot. You might be able to use compressed air and blow out your vents and fan blades. Dust builds up and limits air flow causing extra heat, and then shut down. IF your running your laptop on your lap, make sure your not covering any vents or air flow. Its easy to do and not realize it.

My Averatec 3200 keeps shutting itself down. The


A common problem with all laptop is dust. Sounds like you have 5 years worth of dust stuck in there. You should get a can of compressed air and blow though every vent you can! You want to loosen the dust that's in there and possibly try to blow it out and/or get it closest to the vents.

After that you should take a vaacum cleaner and **** out all the dust you can!

Dust inhibits air flow, alot! Its the number 1 killer of old computers.

Sounds like you have a hardware fan & vent, the CPU shuts down when it gets too hot.
Check the fan, it should spin freely, clean the dust off the fan and heatsink assembly. Replace the fan if necessary.
When you use the laptop, make sure none of the vents are covered.

Gets to hot and keeps shutting down


1. Check to make sure the air vents are dust free.
2. Check to make sure the fan is working.
3. If it is dust free and you can feel the fan working, then you may need to reapply new thermal compound between the heatsink and the cpu. This involves removing various components on the computer such as the power switch cover, the keyboard, and possibly the lcd screen.

Thanks and please take a moment to rate as fixya.

Shutting down


Make sure it is not sitting on the floor/carpet etc. Also make sure it's sitting up right and not layting flat. Make sure it is sitting in it's silver stand. If the vents on the bottom or back of the wii are covered in any way it will overheat. Also, you might blow out the dust from the bottom vent.
