Satellite C55-PSCG8E FAN running fast when pluged in

Hi There,
My laptop's FAN is running really fast and loudly when plugged in AC power source.
However the FAN runs quietly when the battery is used.
The laptop is new and so far only the antivirus application is running.
Is this a normal behavior or an issue ?
Normally a FAN run as fast when the CPU is hot and many applications are running.
regards,

Hi Yassine
Dont be worried about this notebook behavior this is nothing unusual
The reason why the fan is running faster when AC adaptor is connected this very simple: the Windows system use different settings using the battery or mains power.
Using battery mode, the system is configured differently in order to save battery power and to increase notebook working time.
You can change the settings in control panel -> power options.
Here you will find different power plans
Click on the current power plant and check the Change Advanced power settings.
Here you would find the settings for cooling method (sometimes its placed within the Toshiba power saver or Processor power management).
There you can change System cooling policy: you will choose either passive or active
Maybe this FAQ could be interesting for you:

  • Fans running faster when computer idling

    I installed Snow Leopard on my late-2008 MacBook Pro a week ago. It has been running fine except for the following. At night, I leave my mac on to download torrents using Vuze. I lower the screen brightness to zero, and disable the energy saver features. The computer has been getting hot, and the fans really spin fast. It never did this with Leopard.
    Funny thing is, when I raise the brightness and actively use the computer more heavily (Vuze running in the background, other apps also running), it cools off and the fans spin down.
    Any ideas on what's going on here?

    How to reset SMC on MacBook Air and MacBook Pro (Late 2008 and later)
    1)If the computer is on, turn it off by choosing Shutdown from the Apple () menu.
    2)Connect the power adapter to a working power source.
    3)On the built-in keyboard, press (left) Shift-Control-Option along with the power button once.
    4)Wait 5 seconds and press the power button to start the computer.
    Note: You must use the keys on the left side of the built-in keyboard.

  • Satellite L750-A218 - Fan run faster after BIOS 3.30 update

    Hi,
    here is a new issue I am experiencing after the BIOS update.
    I feel the internal fans are spinning all the time by placing my hands near the keyboard. Fan speed according to Toshiba software is 50%+ while I am not doing anything. On the other hand, it was at 25% before the update.
    Did they update the BIOS to give the laptop more ventilation or something.
    This is weird. CPU temp is 45%. I have upgraded from 3.00 to 3.30, for your information. Thanks.
    P.S. The fan speed is stuck at 50%+ and wont go lower than that.

    Yeah, I figured they updated the fan work.
    Though, its really annoying. Why keep the fan at 50% even though the CPU is at 4% and no work is being done. Actually, what I think they did is set the fan speed at 50% minimum. I can feel the vibrations of fans while resting my hands on the rest pad.
    This is driving me crazy. That is because I type a lot.
    I upgraded the BIOS hoping that I will be able to install HDD Saftey software and that did not work.
    Above that, I gained a new problem. The BIOS software did not give me the chance to back the BIOS up.
    Totally inefficient, I checked the BIOS updating tutorial and there was this software that offered that.
    Though, mine was not like this.
    It actually started the flashing automatically. I wonder if someone can feel the fans working like me on other laptops of the same model or family (L750 and L755).

  • Satellite C55-A - after BIOS update cooling fan runs faster

    Hello,
    I was informed by Toshiba application that new BIOS version is available I confirmed it and BIOS was updated. Now I have problem. Cooling fan runs faster than before and it is very annoying.
    Can I find older BIOS version somewhere and roll it back? I don't need it if it doesn't work properly.
    Now I have version 1.40. Is there some solution for this new version?
    Message was edited: posting has been translated

    Toshiba EU driver page provides only the latest BIOS version.
    Furthermore the BIOS downgrade isnt possible using the win-bases BIOS update.
    In order to downgrade the BIOS on Toshiba unit, you will need to use the traditional BIOS update method which requires special BIOS version. This is available only for authorized service provider.
    At the other hand there must be an serious reason why the cooling module run faster.
    Maybe the cooling method has been improved in new BIOS just to ensure that internal parts would be cooled down properly.
    Its just an assumption but I think it makes sense
    By the way: after each BIOS update, you should load the BIOS default settings and should save the changes. If you havent done this in the past, do it

  • G4 Wont Start Up No chime and fan runs fast.

    Hi Mac Users,
    I am at my wits end! My Mac won't start up.When I switch it on there is no chime and the fan runs fast.
    I have checked the battery and it is OK.
    Tried the reset button and no joy.
    I have reseated the ram memory still no improvement.
    I am completely lost without my computer would some kind soul point me in the right direection?
    It is the hub of my recording studio and my life cos I'm disabled.
    I have read a lots of posts on here and I feel I am getting confused with too much information.

    The red LED indicates power to the logic board, which is good.
    Try Resetting the Logic Board
    Resetting the logic board can resolve many system problems. Whenever you have a
    unit that fails to power up, you should follow this procedure
    before replacing any modules.
    1 Unplug the computer.
    2 Press the Power On button on the front of the unit.
    3 Open the side access panel.
    4 Remove the battery from the logic board.
    5 Wait at least 10 minutes before replacing the battery.
    6 Make sure the battery is installed in the correct +/-
    direction.
    7 Reassemble the computer and test the unit.
    Note:
    This procedure resets the computer’s PRAM. Be sure to
    check the computer’s time/date and other system parameter settings

  • Ram upgrade to 2GB - fan running faster

    I have just upgraded my intel mac mini from 512 MB to 2 GB using a kingston upgrade kit (KTA-MB667K2/2G).
    The system is performing a lot better but there is an annoying "trouble": when 2 GB are installed the fan is running more fast and more often then with 512MB.
    During my tests, I have see that while using OS X the system is able to regulate the speed, it goes from very slow to very fast but it moves to fast more often then before and the system is definetly making more noise.
    The bigger problem happens when booting using windows XP: when 2 GB of RAM are installed the fan is always running at top speed or near to top speed.
    That is not happening while using the original 512 MB.
    I have tried to reset the SMC by using the apple istructions here:
    http://docs.info.apple.com/article.html?artnum=303446
    but it didn't make any difference.
    I have double checked all wires,I have switched from 512MB to 2 GB and from 2 GB to 512MB three times(!) but nothing has changed:
    - when using 512MB fan runs slow;
    - when using 2 GB fan is still able to change speed but is running fast more often.
    Further more, to test, I have also left disconnected the fan speed cable in the front side, and in such way the fun starts at max speed and runs at fast speed all the time. So it is not a trouble with such connection.
    Is that normal this behavior?
    Does anybody have noticed any fan speed difference after RAM upgrade?
    About BootCamp and XP running fan at max speed, could be that reinstall them could solve the "always on" fan trouble with 2 GB?
    Thanks a lot for any help.

    I have some updates about the problem.
    I was thinking that it was a my fault about some missing setup needed when installing more ram to mac mini.
    So, today, I have moved to a local apple center and I have asked them to install the RAM for me... they do, and it happens the same thing: the fun was running very fast quite often under OS X and was always fast under bootcamp-XP.
    I have asked them why this happens and if that was normal, but they have no other mac mini with such amount of ram and they never see it before. They suggest me to test it for a week and eventually to give them the mac for a day to make some hardware tests.
    Later, back into my office, the noise was too high and too annoying so I have called again apple to explain the situation.
    They told me that they have no reports about similar problems, that it should not make more noise when adding RAM. They suggest me to try remove and reinstall better the RAMs or to try different RAMs (I am using kingston kit KTA-MB667K2/2G).
    So I have also phoned to kingston support, and they say that it is a strange bahavior, that they don't have reports about that too. They are now investigating the problem and they let me know something in next days.
    They also put to my attention the fact that the computer is able to see and work well with the 2GB memory, so the memory is working correctly. They think this is something related to apple hardware/firmware and could be that apple should fix it in next realases.
    Unfortunatly, all this new infos and all the time lost for a "simple" memory upgrade didn't solve my troubles and I still cannot use the mac like I need.
    So I have continued my tests by changing the kensington Dimms with other 2 GB dimms by Nanya technologies that were installed on my centrino duo notebook.
    Mac mini was able to see and work well with them too, now the fun speed is a little bit slowly then using kingston ones but still more fast than with 512MB.
    Bootcamp-XP is still not usable due to high fan speed and the high noise. OS X seems to control better the fan speed but it goes high there too for any little thing you do.
    So I have made one more test suggested by kingston:
    I have started mac mini while only one kingston dimm were inside.
    In this way the mac mini was making some less noise that using the two nanya dimms, but it was still to high.
    The last test I made was to check the cpu temperature with different amounts of RAM and results were interesting.
    Using OS X with 512MB, the cpu temperature is about 33 C while iddle; if I try to start parallels desktop with guest windows XP, temperature goes up to 40 C and the fan is still running at quite low levels.
    Instead, while 1 GB of RAM was installed, cpu iddle temperature was 35 C and starting parallels desktop will result in temperature levels till 50 C.
    So there was a difference of about 10 C.
    While doing these test I have left the mac mini open, so once stopped, I was able to quickly feel the RAM temperature with my finger and it was quite hot.
    I didn't try temperature with both 2GB dimms, but I belive it will be surely more high.
    So what I am thinking now is that probably apple is aware about higher temperature inside when using more RAM, so the bios starts the mac mini with the fun running faster because it detects the 2 GB memory.
    OS X is able to control someway the fun so it is not always running fast (but quite often) while using boot camp with XP becomes impossible due to the fan always at max speed.
    I don't think apple's rams could work at lower temperature than kingston ones, so the dubt now is that things are correct in this way.. so intel mac mini with 1/2GB could be a shame due to high level of fan noise... or... my mac mini has something wrong.
    Is anybody here with a mac mini and 2 GB of RAM?
    Anybody could make some test about that?
    Thanks a lot for any help

  • Fans running fast

    OK. When I install the 10.5.8 combo updater and restart the Mac it closes down as far as the screen goes blank, but then the fans start running slow at first but after about 2 minuets they are running as fast as possible, should I leave them running? I have left them in the past for up to 2 hours but then I decided to push the button to force quit, just how long should I leave them running? And is this normal?
    Thanks

    That is a retail upgrade to a new system; not a gratis update within one.
    The ownership & use of a retail 10.5 Leopard DVD installer disc set is required.
    A disc from another computer won't work in a different one, so that's out, too.
    +In your post's signature line, you say the G5 shown is running 10.5.8; if so+
    +do you have another computer now, with 10.4.11 installed? Or was the issue+
    +you had mentioned, due to attempting to run the Leopard 10.5.8 update step+
    +in a Tiger 10.4.11 system? Usually, those kinds of things never get very far.+
    (If you know someone who has upgraded to Snow Leopard 10.6, & has
    no further need for their old 10.5 installer disc set, they may make a deal.)
    Sadly, the normal retail sources for buying a new/unused Leopard 10.5 disc
    set won't have them; so other options and sources have to be examined or
    researched. One possible source may be to call the main Apple phone number
    for the sales support (see web page) at 1-800-MY-APPLE and ask for a Mac
    OS X 10.5 specialist; and inquire about the purchase of the Leopard 10.5 full
    install disc set, which is essentially the retail disc for a complete installation.
    +In regions outside of North America, you may have to contact your nearest+
    +Apple main sale support & inquire about getting the Leopard OS X 10.5 discs.+
    The best way to upgrade to Leopard 10.5.8 is to have a separate hard disk drive
    (if you have a tower computer) for it, all alone; no old Tiger or other OS X parts.
    And if you use iLife, get a later version of that suitable for the hardware in your
    computer; as not all older Macs can support the latest iLife. Some may prefer to
    be using iLife 06 or 08, if they don't have all the newer stuff. Older ones may be
    better with an even older version. Since iTunes is a separate download item, that
    may also be too much for some ancient computers. Of course, newer iPads and
    other items probably need to get into the iTunes store and interface with the Mac.
    Those would require the minimums as indicated by their system requirements list.
    If you are on the lookout ahead of time, getting a clean no longer in use Leopard
    DVD retail installer disc may be a matter of timing and luck, in your vicinity. A few
    weeks ago, a craigslist ad had some Apple OS X software including the 10.5 DVD,
    in the box with book; an iLife 08 in box with instructions, Garageband jam-pack, a
    white Apple usb keyboard, and iWorks 05 in the box with paperwork; all for $50.
    And someone else, a few years ago, gave me an early retail Leopard 10.5 DVD.
    So, I could easily upgrade one of my Macs (again) to Leopard 10.5.8 and have no
    old Tiger system parts inside the computer at all. - A clean break, as I'd done before.
    Be sure your computer has better than minimum hardware requirements to run
    Leopard 10.5.8, including more than enough RAM, large capacity hard disk drive
    with large cache and good read/write speed; and a good Superdrive optical drive.
    If the issue with the 'fans running fast' has been resolved, or is conditional, you
    could add whatever new info you have in this thread. And if you are considering
    an upgrade to Leopard 10.5.8, issues outside of the actual computer hardware
    seem to appear in the Leopard discussion page, if you needed to start a thread.
    Sometimes, getting the dust and other debris out of a computer so it can breathe
    and get adequate air-flow, can help it run cooler. But sometimes, there are other
    possible reasons why, if it is running too warm, for it to be doing that. Do you have
    and use a Temperature Monitor software that an be read in the main menu bar?
    A temp widget is mostly pointless, since in order for that to work, you have to stop
    most everything else & run DashBoard. That can further load the system, to make
    it run warmer; if the issue of heat and fans remains an issue to be watchful over.
    Hopefully a few of your questions or curiosities are finding answers; at times, a
    fair gamble on information can be a google search. If worded adequately.
    Good luck & happy computing!

  • Fans running fast on mac pro

    This quesiton has been brought up many times before, and I've tried the suggestions everyone has offered in resloving the problem of fans running fast on a Mac Pro. In my case they started running fast after Sleep, Restart or after Startup. I have a 2007 Mac Pro and have reset the PRAM and SMC in the past and these, along with updates from Apple, seem to have resovled the problem. Recently, however, I began to have this trouble again and went throught the motions of resetting PRAM and SMC. I even reinstalled my OS Lion to see if that would resolve the issue, but to no avail. So this is why I am writing. In an effort to give someone else a heads up to a new problem I incurred that hasn't been brought up in any discussions on the subject to this point; that I can find, anyway.
    About 8 months ago I had one stick of Ram blow on me. I sent it back to OWC and it was replaced no problem. Then I noticed a month ago that all the RAM on my lower riser, except the replacement stick, had blown. Again, all were replaced and this is when the fan issue arose. I tested the RAM on the Upper Riser in the lower slot and they worked. I put the Ram from the Upper Riser on the Lower Riser Board to make sure it worked, and they did. I did this, however, after thinking I had blown the Lower Riser Board and ordered a replacement...glad I did. I now had 8 sticks of Ram in the Upper and Lower Riser all working well, but had a computer that sounded like a 744 just before take off. After numerous attemptst to fix the problem and searching long on the internet I decided to try the New Riser Board I had bought. It workded. That Lower Riser Board, for what ever reason, must be foul somewhere/somehow. I now longer have the problem.
    So, I suggest you follow all the advice of those who have written before me because their suggestions worked initially. However, if you've had blown RAM recently, or maybe are about to and this is an indicator you have a Riser Board problem, you just may want to check your Riser's one at a time in both slots to see if the fans run fast while Board is in and the other is not.

    When my iBook got hot like that, I would take a break and let it cool down.
    You can buy laptop desks that have USB powered fans on them, such as the Targus Chill Mat.

  • Iavd is 98%, computer gets real hot, fans running fast

    Hello,
    I see from some posts of last year, unresolved, I guess, that iavd (anti-virus?) is
    very high for no good reason, meaning it's taking lots of processor (space? function?) and the computer gets hot and the fans run fast.
    Mine has been doing that for a long time.
    Does Apple know what causes this?
    A fix might help lower my electric bill.
    Thank you.

    Not to mention computer wear and tear. I think it is the nature of the beast though, as all antivirus programs can have a tendency to cause a shorter life expectancy on a hard drive and other parts of the system. I skip the AV altogether on mine, and simply choose to browse carefully and stay away from filesharing apps and the like.

  • XServe fans running fast and loud

    Good morning
    I have searched the information base and tried a few suggestions without success.  Hoping for another solution here.
    I have an Intel based XServe (2008) (OS 10.6.8) whose fans are running faster (and therefore louder) than they have previously.  This follows on the heels of a power outage (two of them actually) here at school, though the server is behind a UPS.  The system identifier light is also blinking in a particular pattern - 4 flashes and a pause repeating.
    The server is up and running, teachers are connecting to it just fine, the RAID is intact and online, the drives all look good according to Disk Utility.  So, functionally, everything looks OK - the fans are just running faster and louder than before - noticibly louder than the other Intel XServe in the rack.  The server is at the top of the enclosed rack with a space below it as it has been for the last 4 years.
    This summer I took all the XServes out of the rack, opened them up, and blew the dust out of them (including a moth - truly a bug in the system), so the all the airways are clean and clear.
    I have tried the suggestions I could find on this forum:
         restarted a bunch of times
         shut down and disconnect everything (including power) for a period of time
         reset the PMU/SMC or whatever it is called doing the front panel buttons with the blue lights on the lower row
         reset the PMU/SMC or whatever it is called by holding down the power button while disconnected from power
    I have installed iStat Pro and the temperatures are averaging around mid- to upper- 30°C and the fans are running around 3000 RPM .  The temperatures aren't signifcantly different that the other XServe, but the fans are running about twice the speed.
    I had to reformat the RAID earlier this weekend and copy over the data files from backup and reassign permissions, but the server was running quietly after that was all finished.  It seems to be post-powerbump that the fans became noisy.
    Sorry for the long post, but I tried to include all the pertinent information.  I would have tossed in photos and videos if I could have!
    Any suggestions would be appreciated.
    TIA
    Greg

    Did a little more searching about setting up LOM on the XServe and I think I have it figured out now.
    I assigned a unique (different) IP address to Network 1 in the LOM dialogue box in Configure Server menu of Server Monitor since I only have Ethernet 1 enabled and linked to a switch using a unique (different) IP address for network traffic between the XServe and my clients.
    I can now see (via Server Monitor remotely) that I have a dead blower in my fan array which, upon closer inspection, is also evident in the iStatPro display (one fan running at 18 RPM).  Hence the blinking system identifier light and the other fans running faster and harder (and noisier).
    Oddly enough, I have a replacement fan array in a box of XServe spare parts.  I now have a weekend task.
    Thanks for all the information to be found and the people participating in this forum.  Love it.

  • Mid 2012 MacBook Air: fan won't run faster when overheated

    mid 2012 MacBook Air, system (tried Mountain lion/Mavericks/Yosemite, all have the same problem)
    WHAT HAPPENED:
    The other day I was watching some flash video on the couch, and I heard the fan running like crazy. The laptop shut off 2 seconds later-- no warnings, just black out all of a sudden. (ps: I usually use it on the desk. Only used in bed/couch for a few times)
    It won't start if I press the button immediately afterwards. Instead, it will restart itself after a few minutes, no matter what.
    I shut it down and let it cool down for about an hour. From then on it wouldn't last more than 5 minutes when used heavily (Facetime, chrome together) and about an hour when used lightly (only one app like chrome). Then it shuts off without warning like before. The laptop felt really hot, and I couldn't hear the fan.
    The battery drop down menu says "service battery", and doesn't disappear after a few restarts.
    WHAT THE APPLE GENIUS SAID:
    I took it to the Apple Store the next day, a genius ran a hardware test, and it showed no problem at all. After the test and restart, the "service battery" warning was gone too.
    The genius said it seemed everything is ok. The battery only ran 159 cycles, and it's supposed to last 1000 cycles.
    But he doesn't know why the laptop would shut down out of nothing. If we had apple care, they could bring it back and stress it out, to see whether it shuts off and find the problem. I just brought it home to see what happens.
    WHAT I TRIED:
    1. Max CPU: the fan doesn't react, still runs at 2000 rpm.
    2. Hardware Test:
              when the laptop is hot, it won't survive the test, shuts off during the test.
              when it's cool, it passes the regular test in 1min30s, showing no problems.
              when it's cool, the extended test cannot last 3min before it dies.
    3. Fan test, it can run at maximum speed. In this case the CPU temperature will drop quickly.
    4. The Enclosure Bottom, Memory Controller and the Mem Bank temperature doesn't seem to change. (I don't know if they are supposed to be that way...)
    Please give me some advice about what you think the problem is, and what I can do about it. Thank you all so much!

    If it didn't show any problems in the Apple Store, maybe its your ambient temperature? Although even this shouldn't cause your machine to behave the way it is currently. You need to record it or something then show Apple the issue.

  • Satellite A660 - Fan running fast

    Hi,
    today I purchased a new A660-1FM i7 laptop. I'm fairly pleased with it so far except the fan noise.
    The minimum speed it runs at is 68%, rising to 75 and sometimes 90% at times.
    It never goes below 68% even when nothing is is running (sat on desk top only).
    Is this normal? My previous Tosh lap top fan just cuts in and out as required.
    This new machine is far too noisy as I use in a quiet room most of the time.
    I have played with all the power options including the cooling settings but does not make any difference.
    Please help as I really don't want to have to talk to PC world (The place I bought it from) as I know they'll be totally un helpful.

    Hi Richard1970,
    I cant agree with you... I have this wonderful notebook in front of me and I can confirm that the fan also stops sometimes as on other notebooks, especially when you use the Eco mode.
    My A660 is equipped with Core i7, 6GB RAM and nVidia GT330M graphic card, so a lot of powerful hardware and Im using Windows 7 64bit.
    If I play games on it for example, the fan runs on highest level but thats normal and its not annoying because I hear the game sound.
    But if I use it for browsing in the Internet, the fan stops or almost runs on very low level. I use the Eco mode and changed the cooling method to battery optimized No problems at all and its really quiet.
    By the way: What BIOS version you have? Im using the latest version, 1.80-WIN

  • Keeping Satellite C55-B901 plugged in even when battery is 100%

    Hi,
    I just bought a Toshiba Satellite c55-b901, and i was wondering whether it is fine to keep the laptop plugged in even after the battery is fully charged or not. Would that affect the battery's life or is it okay.
    I also have a cooling pad that keeps the laptop cool.
    Would you recommend i keep it plugged in, keep using it when it is 100% and only recharge when 10% and stop when 100%, or use it both ways as i like?
    Thanks in advance!

    Do you know the software called Battery Manager?
    As far as I know its part of the Toshiba power saver and it should be preinstalled on the Toshiba notebooks. This tools helps you to handle the battery properly and to increase the battery life time.
