Latitude E6410 NVS 3100M Screen Flicker

This question has suggested answer(s)

Hi,

After I have upgraded to the latest video drivers from Dell download site, whenever the laptop wakes up from sleep the screen flickers wildly for about 10 minutes. The flicker gradually fades. First there are even visible horizontal lines. It seems like the display is set to 40Hz refresh rate but in the resolution panel and the nVidia control applet the refresh rate is 60Hz. With the old driver it worked but I have upgraded because the old driver sometimes crashed the laptop. Is there any setting I can make to get rid of this flickering problem?

Thanks!

  • Almost forgot that I am using Windows 7 Enterprise x64.

  • Hi rawbite,

    I request you update the driver from the Nvidia website. Please find the link below from where you can download the latest video driver:

    I also suggest that you update the latest version of the BIOS on your system from the link below. While updating the BIOS, please connect the Ac Adapter and do not use the system until it restarts after the update.

  • Hi,

    Thanks for the response.

    I have also tried the latest nVidia drivers and it is the same.

    I didn't tried to update the BIOS, but from the description of the update it don't seems that it address this issue.

  • Hi rawbite,

    I Request you to update the BIOS as it controls the way all the hardware components function and check if it fixes. I would also recommend you to connect the laptop to an external monitor while the system is at sleep and wake the system. If it fickers even on the monitor, then the problem is with the video card or its drivers. If it doesn't then we might have to check the LCD screen. This is to check if it is an issue with the Video card or the LCD screen.

    I hope this helps.

  • Hello there,

    I have the same issue. 

    My E6410 display is blinking-flickering very fast. It's especially visible near the edge of the display. 

    I called dell tech support, technician arrived and he had repleaced LCD (LG to LG). Problem still occured. He came again and repleaced motherboard. Problem still occurs. 

    I turned off ALS and another BIOS fuctions, still the same.  

    Problem occurs on multiple OS, even in UEFI sometimes! It looks like the display works in very low frequency (like 20Hz?). Changing from 40Hz to 60Hz and 60 to 40 did not solve that. 


    Any solutions? I attached movies with that issue below (in practice this flickering is much stronger, and after few seconds my eyes are burning, really).

  • Obviously i have updated BIOS (up to A13), drivers etc.

  • Gone for a while, now the problem came back after a restart. Around the web people say that this is a problem of the power manager. Namely that it tries to reduce the screen refresh rate to save battery.

    Having the latest drivers, latest BIOS and the same old problem. Started thinking that it doesn't worth to pay extra for the nVidia video card ...

  • I have a desktop wallpaper with thin horizontal lines (kind of the same texture like the laptop brushed metal lid). On that the flicker is the most visible. It is also quite disturbing on a gray colored parts of the screen. Also, the flicker is more accentuated in the right lower part of the screen.

  • Hi rawbite,

    I request you to go to the BIOS and disable the Ambient light sensor. While restarting the system keep tapping the "F2" key multiple times on the keyboard to get to the BIOS screen. Select light and uncheck "Ambient light sensor".

    I hope this helps

  • Hi,

    I have already disabled the light sensor as someone suggested on another forum, but it don't help.

    Thanks for the suggestion.

  • Problem is that when I first saw this problem, I've had a method for reproducing it all the time, but now it appears sporadically only so I don't even know how to test a solution.

  • Dear Tech Supporter : 

    ALS - I checked that  long ago, with no positive results. Display still flickering.

    Today your  technikan repleced my screen third time - (From samsung to samsung, then AU Optronics). Now it seems to be good, flickering stopped. I'll be checking that.  

    Unfortunately new AU Optics display is kind of 'semi-matt display, when the old one was matt. I bought E6410 with matt display,  no semi-matt.

    I am disappointed with this whole situation, Almost 30 calls in matter of one laptop?

  • I don't understand why they've changed the screen and other hardware for you guys because it is clear (for me at least) that what we face is a software issue. Something goes wrong with the drivers.

    I remember that it first happened after a driver update. Back then I have downgraded the driver back and the issue was gone until I re-updated the driver. I have updated the driver again because I've had crashes on resuming from sleep with the old video driver.

  • You're wrong.  Propably in some cases it may be drivers issue, but generally its hardware trouble. Second display change to AU Optronics from Samsung (previously samsung to samsung) helped for me. 

    Check video which i embended few posts above. It definitely does not looks like software problem. :) 

    It is very popular issue - occurs in M6600 too. Display replace helps. 

  • From the video the flicker is exactly as on my laptop.

    I can tell you that with older drivers it is not reproducing. Unfortunately I've lost the old driver so I don't know which version was (stupid me). The changing of the screen maybe helps because it is related to the video driver AND the display driver and with some type of screens the driver works and with some it does not. Also there are others telling that they only reproduce this on Windows 8. So there could be a problem between Microsoft display driver and nVidia video driver.
