Tecra R840-16J - reboot with the fan at full power and no activity

Hi,
Has anyone found this behavior too?
After rebooting (this happened a couple of times...with the hdd and today with the ssd so it should not be their fault) the windows or toshiba screen do not appears only a black screen, no disc activity and the fan works like crazy!!! I stop this after 1-2 minutes because nothing happen!
Cheers,
paulo

Hi, yestarday I restarted the computer, I would say 10-12 times...and this event appeared again one time, apparentelly with no reason! After 3 min, the fan was at full with no disc activity! Turn off the laptop and turn it on put everything to normal!!!!
I know that my R840 have a fan test (cooling test or something like that....I'm at work now), is it possible that test runs automatically for any reason?
But maybe, as you say, I should check the Bios! But what is strange to me is that this only happens from time to time!
Cherrs,
paulo

  • Tecra R840 - Need help with SSD installation

    Hello,
    sorry again, but I really need some help with this?
    My new ssd (arriving in a couple of days) is a Plextor M5P which is 7mm thick! My Tecra R840-16J have a 9.5 mm thick hdd and for what I saw there is no caddy!
    I would appreciate all the tips to install the ssd in my Tecra!
    Thanks for you time,
    paulo

    Hello Paulo
    As far as I know some models are offered with HDD and some with SSD these models offered with SSD have small SSD holder. SSD is fixed with 4 screws into this holder.
    I really dont know how to help you now. Maybe you should contact nearest Toshiba service provider and ask for help. I think they can check part number of this holder or maybe order one for you.

  • My new macbook air 10.7.3 is running hot with the fan blowing just by using the internet. Is there something wrong with the computer?

    My new macbook air is 10.7.3 s running hot, with the fan blowing after about one hour on the internet. It will also run very hot with the fan blowing when it is closed and in sleep mode, is this normal? My macbook pro did not do this.

    My Macbook Pro 15" Early 2008 model had been running hot for a long time.
    Checked Activity Monitor.  (Applications/Utilities)
    AdobeResourceSynchronizer was taking 83% of CPU usage.
    Did a google search and found information regarding AdobeResourceSynchronizer causing high CPU usage and heat.
    http://forums.adobe.com/thread/822790
    Problem seems to be Adobe Resource Synchronizer.app
    To disable go to: System Preferences > Accounts
    Click the Padlock icon, enter password if needed, click Login Items,
    uncheck AdobeResourceSynchronizer
    I don't know how this got install on this computer.
    I suspect Adobe Reader. AdobeResourceSynchronizer.app is within the Adobe Reader application package.
    Control Click (or right click) the Adobe Reader app, click Show Package Contents
    Location: Applications/Adobe Reader.app/Contents/Support/AdobeResourceSynchronizer.app
    Some other Adobe applications may also cause this to run.
    After disabling this in System Preferences > Accounts, temperature seems to be acceptable.
    Also start Adobe Reader X, go to Preferences, Tracker and in the "Automatically Check for New Comments and Form Data", slide the top slider all the way to the right so is says Never.
    After having done all this and restarted the computer, check Activity Monitor again and see if
    AdobeResourceSynchronizer is still running. If it is you can click on it so it is highlighted and click the Quit button in the upper left.
    This solved my excess heat problem.

  • Equium - Black screen and cant reboot with the recovery disc

    I have a black screen and cant reboot with the recovery disc but I seem to be getting nowhere.
    I find it strange I cant ask Toshiba direct about my problem but I have to wait for a kind hearted person to solve my problem or give me a helping hand

    Of course you can ask Toshiba. Toshiba has Authorized service providers worldwide and I hope some of them are in your country too.
    So please visit Toshiba support page under http://eu.computers.toshiba-europe.com > Support & Download > Find an ASP and contact nearest service provider. Just explain the situation and I hope they will help you.
    Back to your problem:
    It is not easy to say why this happen. The whole issue is not described so well and I am missing some important points.
    Maybe you have upgraded RAM and now notebook doesnt start properly. It is also possible that CPU is defective. It can be so many different reasons for this.
    Best thing you can do is to contact service and ask for help. they can run diagnostic tools and find out quickly what the problem is.

  • T420s case resonates with the fan

    My T420s is three weeks old, and has a rather annoying mechanical resonance in concert with the fan rotation speed. With fan running in normal-high rpm, under an average desktop load, the resonance can be felt on the keyboard, case, etc. And of course it can be heard too, having a characteristic purring sound. Does anyone else have this same problem? I have two memory modules in the computer, could this have anything to do with it?
    Regards,
    Jormaporo
    Solved!

    I also had a similar problem over two weeks ago. The fan devloped a noise similar to DVD drive spinning up as the speed increased. There was also vibration on the bottom of the case where the fan was located.
    I called Lenovo support and after put the phone near the fan, the support tech agreed there was a problem and offered to send someone to replace either the fan or the foam the next day. However, I choose to delay the repair for a week as I was going on a trip. The noise did die down to almost normal level after few days and the vibration is gone, so I end up cancelling the repair.
    Just give them a call, I’m sure they will help you out.
    P.S. Unless the memory sticks are loss (unlikely if the laptop is working), than I don’t think that is the source.

    Hi Lisa 1952,
    What have you done so far to try to fix it? I've tried rebooting several times and it did not work. Tried connecting to iTines but it does not recognize the iPhone.
    My other iPhone 4s restarted successfully after the updgrade but some apps don't function properly. It automatically closes while in use.
    Apple please help. I know it's the weekend but I need the other iPhone to work. Can't use sim with a diffrent phone because it's a micro sim!

  • T43 issue with the fan

    in the last day or so i have noticed the fan in my T43 is making a different sound to usual it's like a whirring grating sound 
    will it cause any problems in usage of the laptop
    i tried blowing the fan it didn't help i opened up the case and tried looking at the fan it seemed ok from what i saw. the T43 works fine and is left on for most of the day will it cause any problems, i always keep it clean and well ventilated  

    you may need to replace the fan, but first try and pump a little bit of WD40 into the fan's axial to lubricate it.

  • My MacBook Pro (Early 2011) keeps freezing, the fan becomes extremely loud and the laptop gets very hot, what can I do?

    Hi there,
    I would be grateful if any one could help me. I purchased my MacBook Pro  13 Inch in August 2011, it was the "Early 2011" version, which was shipped with Lion (I have now upgraded it to Mountain Lion last year).
    Up until a few weeks ago, it was running fine. But recently my MacBook keeps freezing (A circular rainbow appears on the cursor), slowing down, the fan gets very loud and I often have to restart the whole machine. This usually happens when I'm running programs such as Safari, Preview or Microsoft Word
    I only use my MacBook for university work so I only have Microsoft Office and iWork installed, nothing else. I've only used 19gb out of the 320gb available. I've also reseted my MacBook to its factory settings but that hasn't fixed the problem.
    I've checked my AppleCare status and it says:
    Repairs and Service Coverage: Active
    Your product is covered for eligible hardware repairs and service under a custom agreement.
    For more information about your coverage, please contact us.

    I was wondering if anyone had any suggestions to how I can resolve these problems, as it is stopping me from doing my work?
    Many thanks.

    Call Apple and make a appointment, backup your use data off the machine to a external drive.
    Don't bother with TimeMachine if it asks, too long and likley be corrupted and unable to restore, just drag and drop your Users folder to the external drive.

    HELP!!

    Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • Hi I bought the oxford dictionary app a while ago and it worked fine . Now with the new iOS it starts and closes instantly. I don't want to buy it again. Who can I turn to?

    Hi I bought the oxford dictionary app a while ago and it worked fine . Now with the new iOS it starts and closes instantly. I don't want to buy it again. Who can I turn to?

    Try closing the app via the device's multitasking bar and see if it works when you re-open the app : double-click the home button to open the taskbar and then swipe or drag the app's 'screen' up and off the top of the screen to close it, and click the home button to close the taskbar.
    If that doesn't fix it then try a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.
    If the app still doesn't work then try deleting the app from your device and redownload it (assuming that it's still in the store) via the Purchased tab in the App Store app - or resync it from your computer's iTunes (if you don't have a copy of the app in the Apps part of your computer's iTunes library then copy it over via File > Devices > Transfer Purchases before deleting it).
    If that also doesn't get it to work then contact the developer.

    Water damage is really a tough hurdle to get over if the steps you have already tried do not work.
    The next step would be to tranfer your Logic Board to a working 3GS to see if it works.
    If the Logic Board is good or you just want to try one more thing, try cleaning the Dock Port very well with Isopropyll Alcohol. If still problem, at most replace the Dock Port Assembly.
    Throwing good money after a bad iPhone is not a good idea.

  • The fan never stops running and is very loud!

    SMC did not solve the problem.  Any other ideas out there?

    My notebook is under the 2yr Total Care warranty so I'm not sure if opening and reversing the fan direction will void that or not...it likely will. I hate calling HP support, I've experienced the worst customer service EVER from them in the past three times I've called...thats another story though.
    I use my laptop on a cooling pad. CoolMaster allows me to customize the location of the fans so I just put the fans directly under the HD and under the exhaust vents. Even with the fan on the laptop gets warmer than you'd think. 
    Someone else posted a very detailed response about hot between 12-16mos after buying it, your laptop should need to be cleaned...I've owned it since January...Its almost always used on a hard surface like a desk and about 8hrs out of the day its sitting on a cooling pad.
