• Problem of built-in Webcam Latitude E6420

  Hello

  I can't get the webcam integrated on my Latitude E6420 works correctly. It works fine in my browser at times, on sites like this http://vyew.com/s/browsertest/, but not at all in applications such as Dell Webcam Central and Skype.

  Are there other drivers, I can try to install except those automatically detected by Windows 7? I've had no luck in finding such.

  Thanks in advance.

  I solved the problem by adding a StringValue named UpperFilters, with the value ksthunk to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ {6BDD1FC6-810F-11D0-BEC7-08002BE2092F} using Regedit.

• Audio problem with Dell Latitude E6420 and Windows 8.1

  Hello community,

  I installed Windows 8.1 on my Latitude E6420 and I can get the sound to work. I installed the drivers available for Windows 8, but he doesn't play any sounds. The only thing that works continuously via a browser (e.g. youtube). When I test the device "speakers / headphones ' this is for me a"Failed to play test sound."but the"helmet of communication"device works without any problem.

  I can not activate the device "speakers / headphones" because it blocks other applications (Lync 2013) so I have to keep this option disabled.

  I look on the web for similar problems and it all points to the drivers for the video card (!)

  Is there a version of driver for this model? Or I can not use the latest version of the software in this model?

  Hello. See here for a list of Dell of the models that work with 8 and 8.1. Dell recommends not installing 8.1 on the Latitude E6420 model. Dell said 8 is correct but does not provide an audio driver IDT even for 8. I don't think that there will be provided by any Dell IDT audio driver for 8.1 since it is not recommended to install. This means that you must use the native audio driver supplied with Windows. The native driver is generic and you can usually get audio to work when using it but not all functions are working properly. All I can suggest is to find the generic audio driver in Device Manager (I don't know how it is in the list) and try to 'update' by allowing Windows to search for an update on the internet.

  Maybe someone at our Windows 8 jury can suggest an audio driver IDT, you can try to use. If you post here tell them that you already posted on the Audio card to the laptop so that they will not move your message here.

• Temperature of the GPU 103C on Latitude E6420

  Hi, I recently started the Test PassMark Burn-In version 7 on my i7-2630QM Latitude E6420 with Nvida NVS 4200 M 512 M card. During the test, I noticed that the temperature of the GPU is about 103C and software reported "Test failure" due to the high temperature.

  The temperature of the CPU is also high, around 93 C.

  Is this normal? I would return this laptop?

  Thank you

  It is a known problem with the E6420 14 "laptop and the Quad core CPU. I have an E6420 and E6520. The E6520 manages the heat much better and higher out of GPU and 95 c 85 CPU when you run Diablo 3 for an hour on the resolution max and max graphics settings.   My laptop comes with the heatpipe heatsink only, he would downclock the CPU because of excessive heat and same judgment. After I got the radiator double pipe with a new thermal pad, my time is up to 100 ° C max on CPU and GPU and cell phone stops is more due to overheating.

  The problem is Dell packed plenty of power in a computer 14 "laptop. When running at load max, the cooling system can not just keep it up. Dell should really fix this, but you can do some improvements on your end. FYI - don't try if you are not comfortable to do this or are tech / mechanical savvy.

  Here's what I recommend:

  1 make sure you have the latest version of the BIOS installed. Dell changed the thermal curves for the fan of the bios updates.

  2 make sure you have the radiator HEATPIPE DUAL DELL P/N - TYP01. My E6420 comes with heatsink tube bad in the photo below.

  One pipe radiator - ONLY for the DUAL CORE i5, i7. NOT FOR i7 QM QUAD CORES.

  Forum.NotebookReview.com/.../564579-E6420-Owners-thread-83.html

  There is a "gap" between the radiator and the Nvidia NVS 4200 M GPU. Dell uses a NOTE from the ADMIN: profanity removed according to the TOU > heat transfer heat pad. many users have done the following to reduce even lower time by replacing the thermal pad with a wedge of copper sandwiched between two layers of thermal paste / compound. I don't know that Dell probably does not support below this mod even if users have reported the lowest time after the mod which stresses in turn of components less.

  3 order the copper shim kit. www.eBay.com/.../260718120394

  4. use a good thermal paste / made up for example ceramics 2: www.newegg.com/.../Product.aspx

  Finally - browse the forums on this site because there is a lot of information on your E6420.

• Latitude E6420 Dell - made helmet taken stop the internal speakers to work

  recently bought a Dell latitude E6420 i5 - 2520 M 8 GB and I have a very annoying problem with the speakers.

  The sound from the speakers worked until I plugged in the plug of headphones into the computer for the first time - when I unplugged the headset internal speakers stop working completely.

  What I've tried so far without success:

  • Uninstall and reinstall the audio drivers / windows sound
  • I tried Realtek drivers
  • Helmet off
  • Recovery and reinstall Windows 10

  What is strange, is that whenever I have uninstall and reinstall the audio drivers speakers begin to work again until I plug the plug of the headphones and again speakers stop working. Any idea?

  Please let me know what you need to know on my computer in order to better understand the problem and I will change the question accordingly.

• Latitude E6420 Sound going headphones instead of speakers

  I'm on a Dell Latitude E6420, and I'm having a problem with my speakers.

  What I have found is that by default, the computer sends sound for headphones, regardless of whether or not they are connected. There are two audio devices in the control panel > Sound, one called speakers/headphones and the other called Communications helmet.
  According to me, that both failed to the headphone, because when you play the normal sounds, they come through the headphones, and when you run the function 'Test' for the Communications headset, that comes through the headset as well. However, when you use the Test a helmet of communication and when you fill out a change in the volume of Communications helmet, the normal sounds (those who play with speakers/headphones) out through the speakers.

  Dell has replaced both the motherboard and the speakers, and after that which did not help, they said I have to just wait for a new version of the driver.

• Update disk SSD - compatibility with Latitude E6420 - E6430

  Hi team,

  My question is this:

  Is it possible to upgrade the Latitude E6420 - E6430 of a HARD single on an SSD drive?

  Technically, I know it's possible, but several subcontractors of Dell technicians are there a lot of problems with this upgrade.

  Indeed, in my business, we did this upgrade on an E6430 yesterday for a client of the beta. This morning, this customer called me to report that after laptop turned on, the display shows "No found boot device".

  Are you aware of these problems?

  Thank you

  Max

  I m having exactly the same problem, after having cloned my SSD HARD drive and attempt to replace the device in my Latitude 6420 - following the Exchange, I get this screen:

  "No found boot device. Press a key to reboot the machine.

  After the previous posts:

  "PXE - E61: Media test failure, check cable,

  and

  "PXE - M0F: exit Intel Boot Agent."

  Max, did you ever find a way to solve this problem?  I would be grateful, as the answers below don't seem to address the problem I faced.
  Thanks a lot - to anyone with your comments here!

• Framework of biometric Latitude E6420 - Broadcom USH drivers windows

  Hi experts,

  Ask you to check this old_post

  I have the same problem, even after you have reinstalled the drivers in the order as suggested by Dell.

  

  I installed "CV_WBF_Setup_Y2GT8_64bit_ZPE.exe".
  [1] double-click on the .exe with option of compatibility in windows 7 and the checkbox on the value

  run as administrator (best option).
  [2] click on ok for a Floder pop-up.
  [3] now install you the driver (this will clear the yellow color material highlighted in)

  Device Manager)
  [4] reBOOT and then install the Firmware (set to the same level provided firmware along

  with driver).
  [5] reboot-> connection (with password :-|) and verify biometric devices in control pannel.)
  you try to check biometric devices in Control Panel and lettering.

  you might get the ERROR below:
  "configuration of broadcom ush host components BrcmFMA.exe - by-side is incorrect.

  Answer posted by "" P3Sal " "

  OK Dell has finally released drivers for Windows 8.  Its a few steps so here's how I worked on all our machines.

  Uninstall the Dell Data Protection if you have it installed.

  Download the firmware and driver here:

  Driver: www.dell.com/.../latitude-e6420

  Firmware: www.dell.com/.../latitude-e6420

  Extract the firmware and install it.  You must run it in high command line and be sure to select the x 64 Installer.

  Reset

  Once installed, you can install the driver from Dell ControlVault

  Restart and you should now see the biometric device.  The software will be Broadcom now instead of Dell and you can save your fingerprints.

  Kind regards

• How to activate bluetooth on Dell Latitude e6420

  How to activate bluetooth on Dell Latitude e6420

  After studying this Bluetooth issue, I learned that Dell don't have not necessarily installed the Bluetooth module on all laptops E6420. I don't see the option on the profile for the online version (hard to believe that they do not have default Bluetooth).

  I got the material via ebay and installed it (not plug-and-play or hardware challenged, but possible if you are willing to disassemble your laptop). Subsequently, the Bluetooth then worked as it should. Yet once, why not Dell make this standard Bluetooth rather than trying to save a couple of cents and cause a headache for users?

• Missing menu of BIOS activation to activate the keyboard backlit on latitude e6420

  Hello

  I bought a backlit keyboard for my 6420 latitude which was only equipped with a model not illuminated at the time I got it.

  By pressing Fn + >, nothing happens. I have read many things on the web, and it seems that we must go into the BIOS and enable the backlit. I said I should find the menu under system configuration and illumination of the keyboard, but I do not have this menu...

  I also had a quick glance and shortcut keys and were those related to the backlit keyboard... Looking at the Control Panel, properties of the keyboard, I do not have the backlight tab, «Brightness keyboard»
  Anyone know how I can activate my backlit keyboard and detected it as such?

  Before buying the backlit keyboard, I am in contact with Dell support to make sure that I can upgrade my laptop with a backlit model without facing compatibility issues. They told me that I just needed to order the backlit model as a spare part and it will work... but it's not...

  Did someone knows how I can get the backlit keyboard work or is it just bad luck and it would never work? Thank you in advance for your help!

  Don't know if this question has been answered but, while I came here looking for the answer that I accidentally he figured out on my latitude e6410, press the function key and the arrow to the right, it has been located here with the brightness of the scree.
