Fan continues to run

I have a HP G70 120EA with windows vista Basic.

The fan on my laptop running constantly at full. Usually the fan works intermittently throughout the day and is usually quiet, but right now, it runs non-stop. The laptop isn't overheating and performance is not affected, but the fan should not be run as this the

I installed an update of the BIOS but that did not solve the problem, can someone help me?

If you have had your system for at least 6 to 12 months, then it's to the point where it is probably enough dust and particles have put in the fans and filters and ducts begin to affect the temperature of system operation. If your fan runs constantly, it is more likely, especially if you don't have not kept the contributions and blown exhaust every two weeks or more. Laptops can draw in a lot of dust and dirt, especially for the people who use them on their "towers" and not on a surface hard as required to ensure ventilation and aeration. The contributions of the laptop fan are on the bottom, the exhaust usually in the back corners. No matter how clean your environment may be, clothing & skin particles, hair, dust, dirt, you name it and it will get finally inside your system. For most laptop computers, depending on the size, happens between 6 and 18 months, usually about 12-16, until they begin to have problems because of the dirt and debris inside heating. Generally, the system, faster it builds, but it also depends on how many times it is used.

Particles and fibers of clothing are especially a problem, and also why you should never use your laptop on your lap. One, it blocks the water intakes and two most of the clothes are made of a mixture of cotton, cotton is a great heat insulator and something you do not want inside your system. Bare skin is as bad or worse, because it contains particles of skin, hair, and other things that you don't normally see that can enter your system.

You can try first blowing the contributions and exhausts - they'll be obvious dust around them. Blow it when the unit is running. Realistic but, ultimately you have to shoot the cover and keyboard to pass inside to do a good cleaning/rash to accomplish real. If your fan is where it is to run all the time, then you're already at this time here.

There is a common HP Support newsletter which is linked to the Page to support your system and many other systems which covers this issue:

Reduce heat and the fan noise by cleaning the air vents

The fan runs constantly, the PC is running more slowly than expected and generates heat

To remove the cover and the entire keyboard, the library of HP Services shows you the procedure and a video demo on exactly how to execute the instructions to remove and replace the different FRU (CRUS). While it doesn't specifically tell you how to perform preventive maintenance functions (something that I suggested that they add), you can use it to remove the cover and remove the keyboard to switch to the fans and ducts to blow off the dust.

It's really not as hard as you might think. The done key to keep a good which screws go where, and for novices, there are some easy ways to do so.

1. some use a muffin Pan - I don't personally like them as a professional. All it takes is for you, your child, you dog, cat, lizard, whatever, Knock off the table and that you're "screwed" literally while you die in agony, I look at each screw you have removed go flying in all directions.

2 parts case - use a medium of plastic parts, number them with a marker and write on paper where screws for each numbered compartment. Leave the cover on the door closed while you work. Better, but still not great.

3 Ribbon and paper - my favorite. Get a roll of blue tape of 2 ". Detach a strip long enough to cover a piece of paper or poster board and bend back the ends, tape on the surface with the sticky side. On the paper/cardboard, note the location of the screws etc and paste each screws/part of the band. When you remove them, sticky substance does not stick, but it is strong enough to hold small pieces very well.

Of course I did it for so many years I do not use anything but my memory, because they are all pretty much the same. But if you never did, using one of these systems can really help you to avoid a catastrophe.

Air - use air canned and have at least 2 or 3 boxes available and be in a room that has a fan to blow off the dust outside or at least away from the system. USE a vacuum cleaner on any electronic system - laminar airflow at the end of the nozzle does NEVER extremes of static electricity that can literally destroy components. ESD rated vacuums are very expensive, so don't even think about it. Non-conductive tips are not as effective either - it is best to avoid completely, but you can use them at a distance to suck all the dust you ripped. I have always used a HEPA filter or a fan to blow out the dust or vacuum dust of any system I've been working on at the time, so it's not aspire back when I am done.

I say having more than one can air because the propellant becomes useless after about 30 seconds of spray, until it warms up again. Unless you want to spray and keep in waiting, so many in order to use one, then another one like the other retrieves.

Make sure you only keep your system connected to an electrical outlet also while you do this - you don't want it powered of course, but have plugged it into a grounded outlet gives you better ESD protection when working within a system. Never touch an exposed electronic component unless it is on his side, or if you're also well grounded.

You must also download and install HWMonitor, a monitoring program internal system convenient and widely used. It measures the temperatures of all the key components and fans. You can get it on http://www.CPUID.com

This, you should get repaired. I know that this seems to be a chore, but it is easier than you might think and a lot cheaper (and safer) that leave some bozo at best buy or somewhere else you charge hundreds of dollars for it, and you can bet money they'll find something else elsewhere just dust.

  • My fan continues to run away, just bought today

    Hi, I just bought the new laptop HP, but the fan continues to run away even if when I'm not working on it. Is this normal or should I make some adjustments? Thankx

    Hello

    You can navigate to the BIOS screen by pressing the F10 key as soon as you switch on the device.

    You can enter the BIOS and choose the option which disables the ' Fan always ON ", and this should solve the problem.

  • Cooling fan continues to operate on the Z30B Satellite after installing Win 10

    The cooling fan is permanently after the upgrade to Windows 10.
    This is the case for the symmetric mode, but also in ECO mode (activated on the touchpad).

    The two modes are defined in passive when running on battery cooling...

    I tried to activate/disable relevant power settings in Win 10 and the ECO utility, but the fan continues to run: it seems that if Win10 is reversing the Toshiba ECO utility.

    Everything worked perfectly before the upgrade.

    This problem can be resolved, or do I have to wait for an update of the Toshiba utility?

  • Why the fan on my macbook pro continue to run at a fast pace for long periods?

    The MacBook Pro mid-2010

    OS X El Capitan, 10.11.3 version

    Processor: 2.4 GHz Intel Core 2 duo

    iWorks ' 09 has been upgraded to the latest versions

    No new upgrade is available for the system.

    My Question: Why the fan on my macbook pro continues to run at a fast pace for long periods?

    I guess that the fan runs constantly, because the CPU is working at a high rate. I rebooted several times but without any resolution systems. At the bottom of the computer is very hot at times so place the laptop on an object that allows good air circulation. This problem occurs intermittently every few weeks or more. I wonder if it is downloading an important upgrade, do a scan of viruses, or by working as a bot. Lights for hours. Currently, I estimate that it has worked rapidly to possible 6 hours. Thank you.

    It will usually be to dissipate internal heat from running resource intensive applications.

    Download and install a temperature/speed control application.

    Open the activity monitor all THE PROCESSES and CPU to display values between high and low.

    When the fan speeds up, post pictures of both for review.

    Also run Apple Hardware Test:

    Note that an error free AHT is inconclusive.

  • 29 Firefox fails to come out properly and continues to run in the Task Manager.

    It is a continuation of a thread found here:
    https://support.mozilla.org/en-US/questions/997448 by Compumind.

    I pointed out that I had the same experience, especially at the opening of the email links in Thunderbird. I reported also that forced me to go back to 28 FF.

    Moses responded by top wire and suggested:
    (1) download a fresh installer of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

    (2) the release of Firefox.

    (3) rename the folder

    C:\Program Files (x 86) \Mozilla Firefox

    TO

    C:\Program Files (x 86) \OldFirefox

    (4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.

    I followed these instructions carefully but no joy. When installing 29 FF, not only refused to leave (using "exit") and continue to run in the Task Manager up until I killed him after the opening of links in Thunderbird, but I find that he refused to come out after a simple navigation and links.

    Moses had asked that I didn't answer in the original thread, so I re-post here.

    In my view, that there is a serious bug. With Firefox 28... no problem don't except a minor that I have indicated here:
    https://Bugzilla.Mozilla.org/show_bug.cgi?id=1002089

    Yet once I am obliged to 28 FF, although I miss the nice interface and security patches, I need to have a browser that works properly. My wife never even saw the Manager of the tasks before so that's the problem.

    In addition, "guesses" made with this post, the only other thing usual outside that I do, is to have a security policy about cookies (accept by default... I make exceptions for cookies I want to keep and have several that are "allow only for the session.") I also FF the value delete history of navigation at the exit, but that takes a fraction of a second.

    I look forward to when this matter can be addressed successfully and I am able to use 29 FF (and out properly... I can't wait for my wife to follow all of these instructions and it often close manually in the Manager of tasks... or what I want to do this.)

    Good luck for all Mozilla projects. Having installed 29 FF twice and then back return 28 twice, I'll wait and see how this plays out. Please don't send me the standard "start in safe mode", 'restart with disabled modules', 'reset Firefox' stuff (the last time that completely destroyed my browser). I don't think that is what is happening.

    Moses added that there is a problem with the e-mail notifications passing by, so take your time, friends.

    I think now (temporarily) this bug or problem has its roots in "history leaving Compensation."

    I made the leap after a few game with 29 PortableFirefox and reading the blog post linked here:

    [https://support.mozilla.org/en-US/que.../997918#answer-566755]

    .. .and installed 29 FF on my previous FF28 on my box. I unchecked the "clear history on exit" which was only to delete my history, not cookies or anything else, cor - el. My setting should not accept cookies unless I make an exception. Until the FF developers find a way to do this is functional, I'll just have to manually delete the history.

    Furthermore, John99, you want to maybe privacy.sanitize.sanitizeOnShutdown set to 'False', not 'true' If you want to stop the automatic deletion of the history at the exit (attempt).

    I've been running for about 6 hours. without experiencing the bug 'suspended '. So, I can live with that for now until this bug is fixed. It should be fixed... browsers are supposed to be able to do things like that.

    On the other hand, I could find things go wrong... but so far I'm not having a problem.

    I for several hours and will let you know later if things change.

    Kind regards

  • Re: Tecra M11 sudennly freezes and the cooling fan starts to run

    My Tecra M11 laptop is running Windows7 and with a broadband dongle Telstra wireless internet lights up and works normally for a period of time.

    Sudennly it freezes completely and 5 seconds later the cooling fan starts to run until I power off using the power button.
    Clues?
    Thank you

    You must understand that on this virtual path, it is not easy to say what the problem is here.
    I can imagine that some background process starts and increase the use of the CPU at the critical level when the motherboard sensors register at higher temperature of the processor and cooling fan starts to run fast enough.

    Try to check in the Task Manager, if something like that happen.

    I put t know how you have configured your operating system and to applications that run in the background, but also to try to stop treatments that you don't need and change some settings.

  • Satellite P100-324: the Fans are still running

    Hi to you all,.

    Maybe you can answer me the question.
    Is it normal that my laptop fans are still running. I put the 'silent' settings in the bios and forced the laptop to run always on 1000 MHz, if I only use it for writing
    in Word or reading emails.

    It's really annoying. I don't know what to do.

    Thankz for your help in advance

    Michael

    Hello Michael

    It is nothing unusual that cooling fan runs constantly on low speed. On modern laptops, there is a powerful hardware that needs to be cooled correctly. Especially many different processes are active in the background and CPU is standing under pressure. Not much when you use just the laptop for writing, but obviously enough to increase the temperature of the CPU.

    Try it please set the CPU and cooling to a minimum level method. Also check the Task Manager and end the process, you don't need. Maybe this will help!

  • Firefox continues to run even after the release in Manager Windows tasks and has about as much memory to affect other applications

    Firefox continues to run even after the release in Manager Windows tasks and has about as much memory to affect other applications. Firefox.exe must be completed manually in Windows Task Manager. Is there a software patch that will force the release of memory and all the resources of the computer that was using Firefox, when it is finished?

    Hello

    So, I have a strange problem. When my fan starts to run faster it bocome so loud, I can't work.
    What is more strange when he has bocome hard I can't start new programs and programs already running freezes.

    What kind of sorcery is this?

    Sincerely
    By Aspera

    null

    Hello

    This occurs because a process running in the background constraints the CPU at 100% and this creates more heat dissipation and the fan on and short shot more quickly to cool the CPU. In addition, the CPU is locked and therefore the system hangs for a while.

    You should check what method or tool stresses the CPU.
    You can start the task (CTRL + ALT + DELETE) Manager and check the processes tab.
    Here you can see in the CPU column which processes are using most of the CPU performance.

    Hello

    Case fans will always run so how (speed) is the question.

    Your PC can be covered by the warranty.  Did you check the warranty status?

    Open the PC and use a can of compressed air to blow out all the dust, including the dust of the heatsink from the CPU.  While the PC is open, disconnect and reconnect the connector to the case fan goes to the motherboard to make sure the connection is tight.
