Question about Acer Aspire 7720 Notebook

3 Answers

Laptop overheating/Bad ventilation design.

About 10 months after buying my laptop, it starts to suddenly, without any warning, shut down. Then, just after a year it shut down and wouldn't start again. Basically, the laptop was overheating due to bad ventilation design. Because of this problem, it burnt my hard-drive. I had a friend who works with computers replace the hard-drive, load a new OS onto it, and generally make the laptop good again.
I now have to have a cooling stand operating all the time to prevent this happening again, which basically defeats the purpose of a laptop. But now, even with the cooling, the temperature sometimes still gets very high!

Can anyone please help me out with this problem??

ARE ACER AWARE OF THIS PROBLEM? AND IF SO, WHAT IS THE SOLUTION........WHY HAVE THEY NOT DONE A RECALL??

I just fixed this with my daughter's laptop Acer Aspire 7720. The prolem was with lint covering inner side (facing cooling fan outlet). To fix:
- open the big cover on the bottom for the memory slots - well it covers everything: processor(s), memory clots etc.
4 screws, the cover also held by snapping little plastic tabs, do not be afraid to open but be rather carefull, do not just yank it open, you will see the fan facing back of the laptop in the corner, it suppose to blow through the heat sink.
- remove the fan, 3 screws, the screws are very little so be careful, you will see the inner side of the sink more likely coverd with lint, dust etc.
- carefully remove using tweezers and blow using canned compress air dust remover.
- assemble back in reversed order.

without removing the fan it is not really clear what it is I almost accidentaly saw it...

do not be afraid to do so you just need small screw driver. magnetic screw driver helps to handle the screws but be carefull with it as some components may be sensitive to magnetic field...

this did the trick for me I hope it works for you. please spread the word as I saw many posts about it in forums...

I use a product called the Laptop Flip which basically raises the back of my laptop decreasing heat by about 30%. I really like the functionality of the product and it solves the overheating issue. http://newpcgadgets.com/products/laptopflip/index.html

HP Pavillion tx2-135dx laptop overheats


hi.Fan Always Runs Or Laptop Overheats And Shuts Itself Off
Warning! Before Disassembling Laptop always unplug power and remove the battery.
Laptops that shut down without warning are often experiencing overheating issues. Overheating may be a symptom of age, of clogged ventilation or impending failure, but it can also result from simply using the laptop in a bad location. Before you try to take the laptop apart to look for problems, it pays to patiently troubleshoot the symptoms and see if an easy fix is possible. I wrote The Laptop Repair Workbook to teach basic laptop technology and troubleshooting to regular people and techs in training. The overheating flowchart below is one of twelve flowcharts in the book.wfwmoavismn7iaaaaasuvork5cyii=

Fix OVERHEATING Notebook


This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:
  1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
  2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
  3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
  4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A135) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

The most common problem you get with a laptop is overheating, this can cause for it to shut down while operating to prevent more damage.

You will know if your laptop is overheating if it happens one ore more of the following:
-The keyboard and the bottom of your laptop are very hot when the laptop is working.
-The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
-The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
-The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
Follow this steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave the laptop in a closed car on a sunny day
-Don't place the laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible, not on your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner.

If it is not overheating, then it is a hardware failure. Could be the RAM memory, or the motherboard. You can only corner the problem by testing with different RAM modules or motherboard.

Turns off suddenly


Laptop turns off suddenly? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage.

If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed.

Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot.

The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down.

Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

My asus notebook m6b00 keeps overheating and tunring off why?


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.
