Dell said 8 is correct but does not provide an audio driver IDT even for 8. Dell recommends not installing 8.1 on the Latitude E6420 model. See here for a list of Dell of the models that work with 8 and 8.1. Is there a version of driver for this model? Or I can not use the latest version of the software in this model?

I look on the web for similar problems and it all points to the drivers for the video card (!) I can not activate the device "speakers / headphones" because it blocks other applications (Lync 2013) so I have to keep this option disabled. 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. The only thing that works continuously via a browser (e.g. I installed the drivers available for Windows 8, but he doesn't play any sounds. I installed Windows 8.1 on my Latitude E6420 and I can get the sound to work.

How to activate Bluetooth using the switch wireless on dell latitude e6420 (early 2011) I solved windows native audio driver installationĪpparently, this is a known problem with drivers Realtek on Dell Latitude. 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. 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. Uninstall and reinstall the audio drivers / windows sound.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. Recently bought a Dell latitude E6420 i5 - 2520 M 8 GB and I have a very annoying problem with the speakers. Latitude E6420 Dell - made helmet taken stop the internal speakers to work I hope this helps someone else with the same question because I certainly not a password within Dell Secure Manager software until this question and cannot conclude that, by not defining a software Dell create a default value for me and it is impossible to understand. I then restarted with all reconnected and housed without reset nvram and dell smart manager secure popped up again but this time I entered the new password I had just put in windows, held my breath for a few seconds and he agreed this password. Glad it worked first try, I wanted to make sure that it happened again so I opened software Manager secure Dell who was installed and tried to change password option and was able to change the password to something I can remember easily. Now reboot and while restarting connect a small wire or loose piece of solder between the 2 pins and the PC should start without going through this request for password allowing you to boot into the operating system. If you don't know what PIN is that, if you look at the chip, you will see a circular impression on the face of the chip, this indicates pin1 and the increment of numbers in a movement to the right anti.įirst thing I did was to reconnect the drives and everything you have also disconnected and then I tried a normal startup to make sure that everything is properly connected and you will notice the secure Dell Manager is always appearing.

If you look to the top of the datasheet of the component, you will see pins 5 and 6 are signals CLK Serial Data In, these are the 2 that short pins must be. There are 2 x 8 pins winbond chips side by side 25Q16CVsig and 25Q64CVSIG, the 8 MB that I focused was the 25Q64CVSIG of chip of 8 MB. I found the flea when ideally placed under the keyboard and are easily accessible. The most irritating part is hoping that you detect the chip before complete disassembly disassembly is reached.

Then against this option, I decided there was nothing to lose by trying to reset the nvram chip.

The only safe option, I had was to replace the motherboard. I have been unable to source any help for this and conversations with Dell where unproductive.
