Question about Acer Aspire 7720 Notebook

1 Answer

Acer aspire 7720-6155 overheats and shuts off under moderate use.

Watching any kind of video, flash or otherwise will cause overheat and shutdown. Linux and MS Windows Vista, happens on both.

What could be the problem and hopefully a fix.

    Thanks Geekman,

    I tried to get into the housing but it seems there is some
    screws or something blocking my access to opening the vented cover where the fan is. The fan is purring away and still in vista even though both cores of the cpu show activity, and fan increasing and decreasing with use, it still shuts off after a few tries on video play.
    I'm going to have to take it in and see if a repairman can break into it. I'm curious mostly about the heatsink. Something a little over my head on laptops.

    Thanks for the quick response.

Check to see if the fan is working, if not replace it.
If the fan is working and spinning freely, then clean the vents and remove any dust/lint.
You may need to remove the fan/heatsink off the CPU and clean off the old heatsink compound and replace it with fresh heatsink compound and reinstall the fan/heatsink.
When using the laptop, make sure it is on a firm flat surface and none of the vents are obstructed.

My Gateway nv79 laptop overheats and shuts off. I thinks it only does it when I'm watching netflx, hulu doesn't seem to do it (I could be wrong). I do know it's over heating though...It used...

When the CPU overheats it goes into thermal shutdown and will not boot up again until it has cooled down.
The heat sink may be clogged with dust and causes the CPU to overheat by reducing air circulation over the heatsink.
If you are not using your laptop on a flat surface, it may beobstructing the cooling vents on the bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

I have and ACER aspire 5738G (1yr old now), everytime im playing games, the left portion, exactly below the power button is getting very hot after 30 mins, then my laptop will shutdown.

Games will cause more heat as they put your components under more stress. Make sure that you are not blocking any of the vents and also, check them for dust. Give them a vacuum if they are dusty. It sounds like there is not enough ventilation, which causes your computer to overheat and then to shut down.

Hello im getting extreme overheatting on my acer aspire 5720z im using a cooler pad under my laptop, anyway sometimes it just shutdown. its clean too. how can i set up the fan to run all the time??

Try to clean the heatsink of your laptop to avoid dust. Unfortunately, there is no 3rd party utility to control acer laptops fans. You would have to clock down your cpu/gpu to avoid over heating.

My aspire 4730z overheats and shuts off even with a fan under it and our best buys geek squad said it wasnt designed to watch dvds even though it had a player. its under 1 year old. what can we do?

First make sure the laptop is lint free, specially around the fan's area and on the coil.
You'll notice hot air coming out of your laptop from it.
Usually gets clogged up with accumulated dust.
Use a vacuum in both areas.
If it gets better, but still shuts down, then you need a heatsink cleaning, and a fresh heat release compound for the processor as well.

ACER ASPIRE 3000 gets power off after some time automatically

If the laptop shuts down by itself and deosn't boot up again after some time, then the problem could be an over heating problem. The CPU shuts down when it overheats (thermal shutdown) and it is usually caused by a faulty fan and or the fan and heat-sink is clogged with dust.
Check the fan and if it does not spin freely then replace the fan and or remove the dust from the fan and heat-sink assembly.

My acer aspire 5738g shutdown while i plaay agame

You either overloaded the processor or the available RAM. Also with these laptops and high end is very easy to overheat them unless they are on a cooling pad with another external fan blowing cool air over them, without it they will shut down due to thermal overload....this is to keep them from melting something. Try checking with the support driver page for your laptop and see if there is a BIOS update that addresses the algorithym for fan speed, then pull the heat sink from the processor, clean everything up and apply a good thermal paste compound, then blow out all the airvents and make sure there are no restrictions.

ACER Aspire 5720 overheat problem?

Try to keep as much ventilation under the laptop as possible.
You can pick up a can of power spray and blow out the unit yourself or have a pro. do it for you.
Dust and lint play a deadly part in overheating with laptops.
Walmart has Ventilation trays in which the laptop sits and is cooled by forced air from underneath.
Make sure the direction of air flow is the same as your laptop.
You dont want to push air into a output vent.

Shutdown Issues

It could be overheating, either you need to replace the fan, or at least open it up and remove any dust (bunnies) that may have built up inside, if your fan is gummed up it won't spin which then causes computer to overheat.

Acer aspire 5610z

need more info....does it replicate without the battery? If it does, then it may be that the processor is overheating and shutting down the computer. Try to run with just the power adaptor and see if it happens. If it doesn't, then its probably the battery....
