My computer turns on and off

My computer keeps turning on and off. I thought it was an overheating problem and i cleaned up my fan, but i didn't see any change. I thought it was the battery too because when i plug in my charger, i don't see the battery charging. So, i took out the battery and run my computer with just the charger, but the problem persists. The weird thing is my computer works properly when i put it on my lap, but it will turn off and don't charge(the lights on the computer don't come up) if i put it on the floor.Please help!!!! thanks

Try moving it to another room and see what happens ,it could be interference.
also vacuum the air vents on the laptop.
It sounds like a hardware problem ,if it still has warranty then you should take it back

Running an Acer Aspire ax5900. The video card fan vibrates loudly for the first 10 minutes of startup. I'm told I need a new video card. Area is clean and dust free. Where is the best place to find a...


Your Acer Aspire, like any other desktop computer system, contains fans inside the case to help vent the heat generated by the internal components.
These fans generally operate quietly and reliably, working in the background to prevent your computer from overheating.
A fan that sounds excessively loud could indicate a problem such as overheating or loose internal components, or it could simply be a normally loud fan.
The key to differentiating between the two involves looking for additional clues from your computer.
Normal Operation
Due to computer configuration and build quality, the fans in some desktops sound louder than others.
Depending on what other brands of computers you've owned or have had experience with, the fan in the Acer may sound louder, when it's actually functioning perfectly.
The fan will run to keep the inside of the computer from overheating, so periodic runs are normal. If the fan runs for long periods or very often, you may have a deeper problem.

Fan Damage and Overheating
A fan can sound loud due to damage, such as broken blades or to a build-up of dirt that impedes normal operation.
This dirt, as well as normal wear and usage, can wear away the lubricant coating on the fan's internal shaft, causing the blades to make excessive noise as they turn. In many cases, a loud fan indicates that the computer is overheating, causing the fan to run more often than usual to try and cool the system.
Depending on the types of components and upgrades within your Acer computer, your current fan may be too small and weak to handle the heat output, and require upgrading to a larger, more powerful fan.


Troubleshooting Take note of when the fan turns on and how long it runs to determine any distinct patterns, whether if it occurs only during certain processes or programs.
Your computer's CPU generates a large amount of heat while in operation, so programs that require large amounts of CPU usage may trigger the fan more often.
Watch for additional signs of overheating, such as sudden shutdowns or computer crashes. Check inside the case for signs of other components touching the fan and causing vibration noise.

Solution

Do not overtax the CPU by opening numerous processor-intensive programs at once.
Check that all screws, cards and wires are securely fastened and away from the fan.
Keep your computer clean inside and out, to prevent the build-up of dirt on the fan blades or air vents and minimize the threat of overheating.
Apply a drop of oil to your fan's shaft to give it proper lubrication and smooth, quiet rotation of the blades.

There is a couple of things that could cause this. This oven has a cooling fan that is supposed to keep the electronics from overheating. There is a thermo cut-off that is supposed to shut it down if this happens.
If it worked like it should, all you have to do is replace the thermo cut-off and possibly the fan. If it didn't the control board will also have to be replaced.

Your electric fans are attached to the radiator,you would be wise to have the dealer check this out,they can access your computer and make the fans turn on with there computer,could be engine temp switch,fan relays,fan fuses,fan motors,that way your not just throwing parts at the problem

The reason why it shuts off when you put it on the floor is because there is a lack of circulating air. Laptops easily overheat if they are not raised up to circulate properly. On your lap, there is more circulation...because it's not a flat fixed surface. To check and see if it's an overheating problem, you need to enter the BIOS and check the clocking time. You are correct, however, typically 9 times out of 10 when it keeps resetting it's an overheating problem OR a virus.

Laptops are difficult to troubleshoot hardware without completely disassembling the entire laptop and I wouldn't attempt to explain to you here how to do that. I would suggest seeing a technician. I doubt highly that it would be a major issue with the motherboard in a laptop unless someone messed with it. There is a setting in there as well that can be changed, but again major hardware disassembly to reach the motherboard.

I think you were on the right track with overheating. Many laptops have more than one set of input and output air vents. Maybe you cleaned out one but missed another one. Since you said the laptop turns off when you place it on the floor I'd look for partially clogged vents on the bottom of computer. Brush away any external dust on the vents with an old toothbrush. Then try blowing air through the vent holes with one of those cans of compressed air made for dusting off keyboards. Sometimes the dust is buried inside the machine. I once worked on a Sony laptop that I had to take apart to completely clean out the vents.

My computer keeps shutting down.


Yes.... that is exactly what is hapening...
Try Cleaning out the laptop for starters...
(i recommend getting someone who is experienced)
The Fans Need to be cleaned.. the Heat Sink(s) need to have their Fins cleaned out... and I would Replace the Thermal Paste on your Processor Chip with High Temp Silver Thermal Paste instead of the typical **** they throw on it..

then another good idea is to look for a 3rd party Fan Controller for your laptop if you are a gamer, it allows you to run your fans when you choose and keep them on if you choose, which would help with cooling your laptop while gaming...
