Question about Acer Aspire 5610-4648 Notebook

3 Answers

Aspire 5610-4621 My laptop is on for most of the morning and will suddenly shut down. Will try to turn back on but will only get so far. Shuts down again. I have let it sit for a few minutes and I can then start it again. I had taken it into a computer shop and it worked fine. Used it for a week and then all of a sudden it shut down. Repeating over and over after trying to get it to run. Checked all my electrical outlets - checked all the plug ins. Thought possibly it could be the CPU fan. Overheating?? Need a new CPU fan?? Any suggestions would be greatly appreciated. Dianne

    Thank for your suggestions: I have my laptop sitting on top of a file cabinet as I stand in front of it. It is only raised as far as the legs on the laptop allows. I will try to elevate it a little more. I do have a backup battery in it so the power source is not a problem.

    The fan is running - it seems clean. It stops and starts which I assume is normal.

    It is running just fine this morning but you never know when it will decide to quit. Hopefully the elevation will help.

    I have the same problem as my Aspire 5610 running Vista will simply shut down ad-hoc throughout the day. I went to the power setting and extended everything in a non-environmental friendly manner to see if that woud help but it continues to shut down randomly. I've tried blowing the fan vent to get rid of any dust build up and will get out this weekend to purchase a riser as currently the laptop is resting flat on a hard surface. Any other suggestions welcome! Jim jigregor@mac.com

My Aspire 5612 shows exactly the same
symptoms. Sometimes its running for hours without a problem. Then it suddenly freezes (preferrably if the processor load is temporarily increased) and the fan starts running at max. speed. After crashing and reboot it usually stops working only a few minutes. After 3 to 5 reboots its operating fine again for up to several hours. Seems to be a common problem (and its not dust related - for sure).
My guess is that the fan control doesn't work properly - the fan starts working too late. I have found a remedy which allows at least web surfing without problems. Run two instances of "Stress Prime" for a high load on the two cores. The temperature will increase and the fan will alway run at high speed. No more crashes!
Does anybody have an idea how to really solve the problem - replace the fan or the temperature sensor, maybe a bios update????

Hi Dianne

Do you have a battery installed or are you running on a power adaptor but no battery at all.
A couple of things I would think about. Firstly, if you do not have a battery installed, install one. There are pros and cons as to whether a battery should be left in if you always use mains. However, if there is a problem with the mains adaptor or any interruption caused by poor connections or intereference, the battery will keep your laptop alive.

Laptop power sockets are notoriously unreliable especially if you are constantly plugging in and removing the power adaptor. Make sure it is firmly pushed home and if it is loose, consider replacing the socket. Also the power lead may have become intermittent.

Yes it could easily be caused by heat. Ensure that there is sufficient ventilation to allow your computer to dissipate heat effectively. I always use a neat home made stand on all my laptops so that even if it sits on my bed there is plenty of room underneath and the vents are not covered or restricted. It only needs to be elevated by an inch or so. I always think of a computer needing to breathe and I don't want to suffocate it.

Can you hear the fan(s) operating? Laptops can end up as dust buckets. Have you made sure the fans and vents are reasonbly clean.

Finally, if you often take your laptop out, something may have worked loose inside such as a ribbon connector.

Hmmm..sounds like a thermal issue....do you, by chance have it sitting flat on a hard table? You know, it's most effective to have a laptop, UP off the table, on one of those 'risers' that are available in most electronics or computer departments. Not unlike a trivet for sitting hot pots or pans on.

got backup for that Acer?

Shuts down immediatley after booting up


Hello,
I can assume from your description and this "click" sound that you are facing an HDD problem. I would suggest downloading Hiren's BootCD from this link. Burn the content on a disk and boot up from it. Then start some of the HDD tests like HDD Regenerator and examine the results.I hope this helps!

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.

When playing certain "Time Management" games my laptop suddenly shuts down. On occasion when I turn it back on it goes through 'repair' and then 'system restore' and still gets hot and shuts down.


Sounds to me like you have a cooling fan issue. Sometimes blowing it out will fix it. Other times it will need to be taken apart and cleaned and new thermal compound put on the cpu

ACER Aspire 6920: suddenly shuts down, refuses to turn on


Hmm I was not sure where exactly to post this but here goes.

Hi I had the same problem a month ago. Though I do have Ubuntu 9.04 rc installed as main OS. It shut down instantly and completely while playing Civilisation 4 under Winblows. Mine is under warranty, so not a problem. But it turns out they had to replace the mother board and Nvidia video card. When it came back. It worked but I guess they didn't check the battery because it is cooked also. They are sending out a replacement. If you have another Acer you might want to try the battery in it first (if it is same size and type, of course ) That way you can fix everything at once. Just my 3 cents worth.
