Lenovo A820 gels

Hi all

Randomly, Lenovo A820 freezes and recharge during calls. This problem happens about twice a day. I reset the phone to default settings, but the problem is back.

I have attached the anr file and the output of the dmesg command.

ANR 2013.08.11 1545.rar

dmesg - 2013.08.11 1541.txt

Please help me solve the problem.

Thank you in advance!

After searching for a few weeks, I found the cause. The phone freezes due to demand on some Orange SIMs who uncalibrates the phone. This problem occurs on all smartphones Android with Mediatek processors. Incompatible SIMs are marked with '03', 'J04', "U06", "P04" and "P08". I changed the SIM card and the phone has stopped freezing.

  • Lenovo Z50 - 70 gel random error

    Hello!

    I just bought a Lenovo Z50-70 (840 M, i5, 1 to SSHD), and I have a very annoying problem.

    Installed Win 8.1 Pro with drivers from the DVD. All right, it is not all errors in the Manager devices, but random computer crashes (the cursor does not move, it is not for nothing), so I have to restart it by pressing the power button for 5 seconds.

    How can I fix? I hope this isn't a hardware problem.

    Thank you for the answers.

    I write my solution for this problem.

    Freezing at random was caused by electrostatic discharge. I used the laptop in a glass surface, and when I touched the metal parts, the discharge made and caused the gel.

    I put my laptop to a wooden table, the problem abandoned.

  • Windows on Ideapad Y510P ExpressCache question - gel Constant 8.1

    Hello

    I recently bought the laptop Y510p and updated to 8.1 windows

    Since the upgrade, I'm telling gel, which could last 10seconds or 10 minutes.

    Any time I restart the computer, it crashes, and the only way to kill him is to press the button works / stop.

    Checked the eventviewer and I found the following disclaimer appearing every minute:

    After much research, I came to the conclusion that the ExpressCache is the cause.

    at the time wherever I've uninstalled it, issues disappeared.

    System will reboot without any problems, it will not be freez.

    Checked the following article:

    http://support.Lenovo.com/en_US/downloads/detail.page?docid=HT074404

    Tried to re - install ExpressCache but the problem started to presist immediately, constant freezing and the message above in Event Viewer.

    Everyone knows the same problem? If you did, did you mange to solve?

    Obviously, I'm happy at this stage that frost has disappeared, but at the same time, I really would like to have full use of the system and would like to get it resolved.

    Any help much appreciated.

    Hello.

    Talked with Support and unfortunately, this seems to be a matter of HW.

    Given that I've owned only the laptop for less than 31 days I received a full refund/replacement code.

    I would say that anyone having the same problem, contact technical support and advises because that is the question to support him rather than S/F.

    Kind regards

  • W510 Gel with Linux

    I have problems with the W510 gel randomly with openSUSE 11.3. I checked ThinkWiki http://www.thinkwiki.org/wiki/Category:W510 and the problem is not here or on other forums.

    Does anyone else have this problem?

    Is there any distro that works correctly with the W510?

    Thank you

    -Don

    Update:

    Install the new Fedora 14 (KDE x86_64) yesterday and works well so far.

    Everything seems to work out of the box (did not test the fingerprint reader and still need to make the fix suspend / hibernate).

    Debian also seem to work without freezing but needs manual installation for network drivers.

  • Lenovo R61 Windows XP freezing

    Hello!

    I have the original cd of Windows XP Recovery for models R61/T61 lenovo.

    I currently have Lenovo R61 type model A32-8933.

    It installs fine, but after it goes off randomly gel:

    -In the bios, I choose the compatibility mode no AHCI, due to the fact that Win XP SP2 do not have the necessary drivers.

    -J' updated BIOS

    -J' updated all the drivers via for the Lenovo system update utility. (no yellow exclamation in Manager)

    -Installed SP3

    -Installed driver Intel matrix storage (no effect)

    Freezes are random, I can't copy them. In Event Viewer, I get no error.

    To stop the freezing I shut down the computer.

    !!!! I am currently using Linux Mint 13 Mate-> not a single problem so far. Fine work, so problem in hardware but not software related.

    And ideas?

    So I put the finger on the problem.

    It WAS WIRLESS CARD - Broadcom 4311 model.

    It was not supported by lenovo and it was the origin of the random freezes.

    Yesterday I updated for Broadcom 4321 model, and it works a lot better + do not freeze.

    I also uninstalled lenovo conectivity programs + Power Manager and it works even better - WINDOWS 7 proffessional.

  • T61 gel when running on battery - no problem when it is plugged

    Got a new T61 2 weeks: 6459-CTO, Vista 32, T9300 2.5 GHz, 4 GB of RAM, Intel Turbo Memory. Everything is fine except the following problem: when running on battery only (not connected) the system hangs intermittently, programs stop responding, ctrl alt del does not work, only solution is a hard closed down. Lenovo sent me a replacement battery but same problem persists. Very annoying! System has never frozen when connected to the AC. All PC Doctor diagnostics OK. Insatalled latest drivers etc. Is update system, including Windows update. I have read that some versions of Intel Turbo Memory has had this problem when running on battery alone, but apparently this has been corrected with the later driver versions of Inter Turbo Memory - I later. Any help would be appreciated.  No problem other than that - I can't use the laptop on battery with confidence.

    All is well so far - no freeze no more! Now I can use my laptop because it was intended to be used - in battery mode - in the yard!  I wonder when Lenovo makes available this driver for their production. This problem of gel certainly did me a lot of grief.

  • Lenovo ThinkPad won't start

    Hello, I'm having a problem with my Lenovo ThinkPad T520 running Windows 7 Professional 64 - Bit. It has a processor Intel Core i5 vPro 4 GB of RAM and a 500 GB HARD drive. It worked fine up until this point. Here is what happened.  It started when I was surfing the web tonight and it froze. I could not click on the 'X' button, use Alt + F4 or Ctrl + Alt + Delete. So I decided for a difficult start. I pressed the power button until it stopped. When I start again, it froze on the Windows splash screen. I waited for about five to ten minutes and started hard again. This time he asked me which option to start, I wanted to use. Start Windows normally or something like return on error. I tried the error recovery option but it was without result. I started again and it froze again. She is still ongoing now. Need help, tell me what I need to do. I hope it has nothing to do with the material because the PC belongs to my work. >_

    Regardless of the fact that he belongs to my work, I am a system administrator.

    You are a system administrator of employment in question of title?  If so, you must solve the problem.  :-)  Or you are just an administrator on the system in question?  Having administrative rights does not make you a sysadmin by title.  * smile *.
     
    No offense meant, but the wording of your question was more like an end user explaining what a system administrator explaining.
     
    You can start safe mode?  If so - how does it work?  You can start using the safe mode with networking?  If so - how it works in this mode?
      
    So you're saying that nothing has changed between her works and does not other than gel?  No updates, no new hardware or software installed, etc.?
     
    Have you tried to use the system restore to go back to a point before the system had problems?
     
    Can you use a Ubuntu boot CD and run it from the CD player to see if the machine starts like that and be usable?
     
    You have the media/method of system recovery in mind and you have a backup of the data, you might need the machine (or a method in place, if you are a system administrator, in order to safeguard a complete system so that you can extract data from such backup after a recovery?)

  • X100e suspended and gel on Wireless

    There was another thread dealing with freezing and hanging connected via ethernet; However, I had ethernet disabled from BIOS from the first day of the receipt of my system, but I found my system to be locked up very often especially when connected to the Wi - Fi connection at Purdue University.

    For reference: the Purdue University wireless network using WPA-Enterprise with PEAP + Thawte security certificate.

    Naturally, I got the latest BIOS (1.25) and had all the updates that are available from ThinkVantage System Update, but appears not to help any - when I was watching on my university network, it would all just hang and freeze completely every 30 minutes or so, forcing me to restart the system.  It seems to freeze regardless of whether or not I was even almost anything on the internet.

    It doesn't seem to be any serious question on my home network, however, which uses WPA2-Personal, but I don't really use my x100e home enough to say with certainty.

    I was quite convinced that there is some kind of problem with either the wireless network card drivers or some sort of power saving at this point, so I uninstalled the Lenovo x100e wireless drivers and got the latest drivers for the chipset RTL8192SE directly to go to RealTek and install them.

    Then, I went and disabled "Allow the computer to turn off this device to save power" for the Device Manager wireless card.  Also, I put the adapter wireless for 'Maximum Performance' and disabled the power management PCI Express link state since the power manager.  I also disabled idle timers to stop watch system hibernation and rotation of the hard drive.

    Now after this small set of actions that seems to me to be more or less surf and download things stably on my university network.  I must point out that the system still crashes every now and then while I'm browsing around.  I note no particular to this hanging trend; It just happens when I open a browser and navigate normally - it hangs for about 40 seconds (I can move my mouse but nothing you will only answer) then it simply returns a normal operation.

    That's my story...

    Everyone has ever seen hanging or freezing on networks wireless with their x100e?

    Hmm so oddly my freezing problems seem to be fixed right now with my new last installation of Windows 7 x 64.

    I didn't really do much of anything special this time and more do not install all the stuff of ThinkVantage. (with the exception of Power Manager)

    On installs previous I simply let Lenovo System Update everything, but this time I went here and downloaded all the drivers for Win7 x 64 manually: http://www-307.ibm.com/pc/support/site.wss/MIGR-74463.html

    Including "Windows Installer supplements" which were applicable to Windows 7.

    The only driver I was not installed from Lenovo page this time was the catalyst which has a much more updated version of AMD.  I usually install the drivers of both ReakTek 8192SE but this time, I installed the drivers Lenovo wireless.

    Now my hanging/freezing problems have mysteriously.  The only thing that never happens now is when I have to leave as an hour with the lid down, I think it's blue armored, but I've not seen any suspension or gel during a use for some time.

    Wireless performance/reception seems to be as crappy as always with the RealTek card... in my University in places where all other DELL, HP, Acer, laptop computer shit etc can connect correctly I get disconnected every 10 seconds...

  • Lenovo U350, cannot start all programs at any given time

    Hi experts,

    I met some problems with my Lenovo U350 Windows 7 again.

    All of a sudden, I can't start any program on my laptop after running it for a while. I click on the program, I can see this program running in the Task Manager, but it does not appear on the screen.

    Also I can't reboot my laptop normally by clicking the "Restart" or "Shut down" buttons or the other. For some reason any these buttons/controls stop working. The only way to fix this is a closed hard down in now "Power" button on the laptop for a few seconds.

    I ran the antivirus check on my laptop to find existing viruses but came out with a result of 0 viruses.

    I wonder why the programs on my laptop stop the loading or gel? Any ideas?

    I'm so close to reinstall the whole system with the OKR.

    Thanks for your replies in advance.

    See you soon,.

    Randy.


  • Gel iPhone... !

    IPhone-6

    software update 10.0.2

    Hello Has1710,

    Welcome to the communities of Apple Support!

    I see that your iPhone is icy and stops working unexpectedly. You lock and unlock the iPhone, and then he answers. Also, you did a restart of the force and restored, and remains the same question. We appreciate certainly take you time out of your day to contact us about this, and I am sure that you are ready to get this resolved.

    You mentioned that you have restored. You have restored to factory settings? If this isn't the case, let's go and save the data to your iPhone (if you haven't already done so) and restore settings to see if you get the same problem after that. Restore factory settings removes all added applications and software on the iPhone which could be causing a conflict.

    The following articles will help with this:
    The backup of your iPhone, iPad and iPod touch
    Use iTunes on your Mac or PC to restore your iPhone, iPad or iPod to factory settings

    Please let us know if that helps.

    Best regards.

  • IOS 10 gel

    IPhone 6 Plus after updating IOS 10 his continue gel sometimes almost impossible to work seeking a quick fix.

    Try to keep these keys at the same time for at least ten seconds, until the Apple logo appears: a) the sleep/wake button and the low Volume button (7 iPhone iPhone 7 and more) or b) the sleep/wake button and the Home button (all other models)

    If that doesn't help, try a system restore. First save your device via iTunes. Also import your photos on your computer and copy all the data if possible. Reconstruction of the support first test and test. If this does not help, you may need to restore as a new and reconfigure from scratch as the backup may be damaged. It is important to have your photos and your saved data separately from the backup. Here are the steps for a restoration:

    If the steps above do not help, you may need to test in an Apple store.

  • IPhone camera on the launch 7 - gel


    The native iphone camera app 7 takes 5 to 20 seconds to launch.

    To reproduce the problem:

    (1) open the native camera application.

    (2) close the app native camera by pressing a button at home (important: do not remove the camera app from applications recently used in multitasking).

    (3) make 5 calls or more, each call 10 seconds or more. For example to call your voice mailbox to simulate a day calls.

    (4) after the calls, open the native camera of the lockscreen app.

    The video below demonstrates the problem:

    https://www.YouTube.com/watch?v=tnhVNhjxfcI

    In this video, it's 5 seconds freeze on iphone 7 (seen at 01:42 from the video). The freezing of the camera is linked to the amount and duration of the calls, more appeals - more it takes to launch camera. The gel may go up to 20 seconds.

    I encounter this problem on iphone 7 (ios 10.0.1) as well as on the iphone 6 s (from 8 IOS iOS 10).

    I have to very good reason to believe, that all 7-6 s iphones are affected by this bug and it can be fixed by restarting, reset, DFU, replacement of new apple id or by phone: I tried to do all these steps several times with my iphone 6 s and it did not help. This issue can be resolved only by Apple developers.

    Please submit this bug to Apple directly under the following link (as it seems that they do not react to our discussion forums): http://www.apple.com/feedback/iphone.html

    This thread is designated for iphone 7 and 7 more.

    The same camera with the 6s iphone problems are discussed in the next big thread since October 2015: shift camera iphone 6s

    The purpose of this thread is to share and spread over the issue, as well as make Apple notice and respond to the concerns of its users in correcting this bug.

    I was part of the iPhone 6s camera gal as well original thread.  My new 7 256 GB iPhone did the same mentioned in your question/statement.  I also reported the bug with the link you provided.  This seems to happen only for the 6 s 6 s 7 and more.  I have restored my backup on a normal iPhone 6 and this problem did not repeat after over a month of use.

    Thank you for taking the time to write this problem!
