Problem of heat T420s

I bought a T420s a few days ago and playing games on it. The upper-left corner of the portion of the notebook become very hot after an hour of play. Is this normal?

Work as expected. If you notice it stops due to heat problems, then you must be it remove or install a new fan. If the system is no longer under warranty and you have the dexterity, you can remove the radiator and the current Thermal Interface material (TIM). Then you can apply a high quality of TIM, reattach the heat sink and walk back the machine. This can reduce your time to a few degrees Celsius.

    The fan makes noise should almost certainly be replaced rather than cleaned.  Work correctly cooler CPU fan makes no noise or so little noise it's hard to hear.

    I took the fan and cleaned it but still the same problem and the fan still makes noise. I don't know how to solve my problem.

  • Adding a GIGABYTE 660 OC will void my warranty? Problems of heat?

    Hi - I wait tomorrow my new 8700 XPS and wonders if the addition of this card will void the warranty? I don't see it on the list of cards approved, although I saw some 660 s

    Gigabyte GeForce GTX 660 OC 2GB

    www.amazon.com/.../B00942TK8I

    I was also wondering if there will be problems of heat with long game several hours a day. (e.g. Skyrim/Assassin Creed/Dragon Age Inquisition)?

    I'll upgrade later from the PSU and video card, assuming the case is pretty cool - I have a Coolermaster EVO that I doubt will fit.

    Any other advice on installation? I don't know if the update of the Bios is required for this card.

    Anyway, thanks in advance.

    warranty shouldn't be a problem. Older GPU do not need an update of the BIOS, most recent need of revision of the A10.

    Here's a whole thread discussing what you plan.

    http://en.community.Dell.com/support-forums/desktop/f/3515/t/19611037

    I don't come by that much money on a 660 GTX when more recent, better, faster cards is available for less money, that draw less energy and generate less heat.

    A GTX 960 will well on skyrim and OK on Assassin creed.

    A GTX 970 will be much better, but the OEM PSU is at the limit

    Cooling is not bad at all, just make sure that the case has a lot of airflow around it.

  • Someone at - it problems of heat upgrade to a 7200 RPM HARD drive in a MacBook Pro 13,3 "2.5 GHz Core i5 (A1278) - mid-2012, MD101LL/A?

    HI - it would be an update of the stock 5400 RPM, 500 GB HARD drive. The 7200 drive I bought is 1 TB.  Thanks in advance for any help!

    As long as it's a SATA HDD with a 2.5 form factor ", it will be compatible.  You experience a slight increase in performance with the faster HARD drive, but it will not appear in 50% faster than the 5400 RPM HARD drive.

    Ciao,.

    Addendum: There will be no observable heat problems.  I did it several times myself on all of my 4 Mbps.

  • Satellite P100-307 - massive heat problem, keypad heater

    Had my Satellite P100-307 for almost two years now and it's a good and useful media-notebook, but it never HOT side left keyboard, especially games.

    But in recent weeks, the keyboard is pretty HOT and I don't know why! Because I6vgt ´m using only low level applications.

    I did a full restore to clean any virus or other malware, but it continues to get hot, as if I where in the highest graphics modes, the games, but just I m using IE7 and a LateX editor for the creation of PDF Documents - that s nothing for a dual-core processor! Kaspersky 7.0 has been throtteld down, as far as the security is allwoing it.

    So why it s heat like that in 30 to 60 Minutes. He has never done this before, I m sure.

    It s so hot, it's quite unpleasant to work with her, because placing even the heel of your hand next to the touchpad makes my hand sweating!

    Looks like the laptop is overheated, it is a common problem with laptops that are used in a dusty environment (a room with carpet, for example).

    Buy compressed air in a box and spray it in the vents to remove dust.

  • Problems of heat with Satellite M70-173

    Need some advice.
    Have in last few weeks found that all side and sometimes in the middle of the laptop its got very hot to the touch.
    Have no idea what could cause this?

    Hi mate,

    I think it could be a cooling system that is full of dust. If the cooling system is clogged with dust and then the machine cannot carry enough heat of your machine which has been generated by the processor and graphics card. The result of this could be overheating, software errors and finish hardware malfunction.

    So, my advice to you: go to the next radio Shack or electronic market and buy a box with compressed air. Some blowing AIR gently hollow the vents and if dust comes out then you know where the problem is. Just clean the entire cooling system and make sure the cooling system is almost free of dust.

  • BlackBerry Z3 is the problem of heating in Z3

    Hello. I bought the Z3 in the last month. Honestly, the unit is higher than my expectations. Thanks to RIM.

    But there is a problem, my phone and everything heats up by using the mode of 3G network also during use of android apps.
    Please help solve this problem.
    Thank you.

    Oh my! Two questions...

    First of all, it isn't an OS level... This is the version of the software, which is something different. Reference:

    Fortunately, I have a reference to provide the value of the BONE, i.e. so that SR 10.2.1.3412.

    Second, this OS is relatively old. As you will see in the reference, there were 34 OS packages published since what you run. How old is this OS, I don't remember if it was the specific issue you report.

    My suggestion is that you try again and upgrade to a more current OS.

    Official methods, which will be controlled as to what exact OS versions are available:

    Non-official methods, which are cleaner and allow you to choose a version of the OS that maybe your carrier (or anyone they control your offers) delays in approval:

    Of course, before you start this, you want a good backup link, a manual copy of the memory of your device to your PC and complete documentation of your configuration (identification information of account, adding applications, configurations, etc.). Sometimes, restoring a backup returns unit corruption even, must be eliminated and reconfiguration from scratch can solve that. Indeed, considering how old is your operating system, it is likely that backup/restore via LINK would be impossible as the operating system has progressed, the backups taken often to older versions of the OS are incompatible as a source of restoration on the new versions of the OS.

    Be aware of the risks of 10.3.2 however... There are two things to worry about. First of all, be 100% sure that you know your BBID identifiers, and you have fully confirmed their... If you do not, you may make your useless device to anyone, including yourself. Second, once you move to 10.3.2, you cannot fall back to 10.3.1 or earlier, by any medium (for example, even the unofficial AutoLoaders can not overcome this restriction anti-secours). Reference:

    Good luck!

  • Problem with heat on initialize to top with Satellite M40

    Hello group,

    I have a question, when my laptop Satellite M40 warm up and I tried to restart the display changes to 2/3 and lock-up. Then I have to press the power button to stop the process and expect that the laptop cools a bit. I have them push the button power and Windows works fine. What is happening and what should be replaced or added software.

    Kind regards
    DJ

    Hello

    I'm not a technician but I can say with certainty that described issue has nothing to do with the software and may not be resolved this way. Problem described is certainly caused by the material. It may be the graphics card itself or a faulty capacitor on the motherboard.

    Technician sorry but only help you and give an exact explanation. All this can be tested with special diagnostic tools.

  • Problems of heat with the mid-2015 MacBook Pro 15-inch with retina display

    MacBook Pro (retina, 15 inch, mid-2015). 2.2 GHz Intel Core i7 | OS X El Capitan (10.11.3) | 16 GB 1600 MHz DDR3 | Intel Pro Iris 1536 MB | 251 GB of Flash storage

    My 2006 13 "MacBook White would get really hot on my knees if I was using the DVD player.

    Since then, my new MacBook Pro has no disc hard turns and no great, should I feel any heat at all?

    There is an old rule to never put your laptop on your lap, because it may damage your skin. I wonder if the new MacBook Pro will become warmer over time, or if I can expect to not feel high heat.

    Is there a range?

    I did have the machine long enough to say that I have done the troubleshooting steps.

    The DVD player is not the primary heat generator, the CPU/GPU are the creators of the heat.  When you use resources intensive applications, you can expect your MBP become very hot.  Video, Skype, games, etc., are applications that will make the CPU/GPU heat, reaching temperatures in the range of 90 ° c.

    You should expect at a temperature between 40 ° c to 50 ° c when running during 'normal' light applications such as text editing and browsing the web.

    Ciao.

  • computer problem of heat

    my computer is running hot if bad, it's too hot to hold on the lap.  It's as if the fan does not work.

    Hello!!

    Thank you for visiting the Microsoft Answers community forum.

    The overheating problem would be a hardware problem. You did not mention the brand of the phone, otherwise I would have given you the number of supported for the provider. Please contact your provider, such as Dell, HP, IBM or anyone. So that they can help you change the hardware.

    Do it as soon as possible, before warranty becomes obsolete...! If check you already out of warranty, with the seller if they provide an extended warranty if they do... go for it.

  • Incompatible Audio volume T420 - Audio problem.

    Hi all

    recently I've been an audio problem with my T420. It doesn't matter if I use the built-in speakers or an external playback via the audio device, audio volume goes up and down several times for a minute.

    It's rather annoying and irritating. I use the standard driver provided by Lenovo and with stock settings.

    If someone had this problem and could give me some advice?

    Thank you very much!

    The framework was already to the people with reduced mobility.

    I thought, maybe that's the problem, I've been experience, because it is only when I used Ethernet instead of WiFi: DPC latency + audio / mouse skip and stutter on t420--Lenovo's community

    I tried the proposed parameters, without success.

    Interestingly, re - install the same drivers that have been installed previously seems to have solved the problem.

    Maybe some settings or installation screwed up.

  • Lenovo K3 note heat problem

  • ThinkPad T420 recovery problem

    Hi all

    I need your help. I have a problem with ThinkPad T420. When I am pressing ThinkVintage or F11 to get into recovery, it loads and then I get this message below;

    Link to image

    Don't know how to solve this problem, thank you!

    If partitions System_DRV and Lenovo_Recovery (q) has not been resized or corrupt, R & R should work. So, I guess to upgrade/reinstall application Lenovo Rescue & recovery via ThinkVantage System Update because there are a lot of conditions to perform this task manually (eg. There are several options for deployment and language packs).

    If this does not help, it could be better and more quickly to create a Lenovo recovery media, it's almost the same Lenovo recovery environment you try to start using BB or F11:
    -make it from Lenovo R & R application, advanced mode, rescue media
    - or simply deploy a .iso file image:
    C:\Program Files (x 86) \Lenovo\Rescue and Recovery\rrcd

    Note, in any case, it is a good practice to have this rescue media.

    If you want to reset the laptop to the factory scene, do it from recovery media factory Lenovo.
