I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

I bought a Lenovo Thinkpad T480 about a month ago. When I completed all my set-up after initial stage, I got the Dolby Advanced Audio Profile editor. ALthough it is different from Dolby Digital plus ( the dancing graphic equilizer) , but it was correct. After the windows update, that Dolby Digital Advanced Audio Profile from desktop is disspapear. I uninstall the audio driver, then re-install it from Lenovo website ( the version of 1809). But I cant see the Dolby Profile again? Have I done something wrong? Please help me regarding this.My Machine: 32GB RAM, NVIDIA and Core i7

My laptop is Thinkpad T480, core i 7, 32GB RAM with Nvidia and 1 TB SSD. Initially I have Dolby Digital Advanced Audio(DDAA) Profile Editor as desktop short-cut ( the editor has a graphic equalizer which can be edited). But after the windows Update, the DDAA profile editor has been disspaeared. I uninstall the audio driver, restart and then again install Audio driver from Lenovo website but the editor did not appear. Even in the C drive , I tried to retrieve but failed. Then I go to Lenovo VANTAGE app and found this. Here, the mode can be changed but there is no graphical equalizer like DDAA editor. What's is the solution of this problem?

Hello everyone, I have a question about my audio driver.I've bought a new headphone but there wasn't much bass when using with my laptop (with Conexant as the audio driver). On my phone, the headset's audio is completely fine (with bass of course). I had a Conexant audio driver and searched on the internet on how to improve the audio. I searched for some tutorials and found a new driver called High Defenition Audio Device by Microsoft. So I updated the driver and now it's High Defenition Audio Device. And my headphone audio has slightly improved. However, the "Dolby" tab (Sounds > Playback > Speakers > "Dolby" tab) is now gone! And my computer sounds like an old radio (no bass, only mid/high frequency really)... Is it possible to get Dolby back? Or is Dolby not compatible with the High Defenition Audio Device driver by Microsoft? I've tried the Lenovo Vantage and saw Dolby options, but they don't work anymore too... Thanks in advance. Kind regards,iiSnewoNL

Hello. I've been looking for a solution for several days with no success so I decided to create my own thread. I've recently bought the G50-80 laptop. I performed a fresh install of win 7 Ultimate x64 on it and I downloaded and installed the most recent drivers from lenovo website. The problem is that Dolby surround sound is not working. The profile selector shows up properly and the equalizer works properly as well but surround virtualizer does nothing, ticking and unticking it does nothing as well as changing the level. My sound quality is at 24bit 44100 khz and I also own Creative Aurvana Live headphones which work just fine on my PC and surround works perfectly. My Conexant drivers are also up to date so the only thing that comes to my mind is that the new Conexant drivers are somewhat broken. Please help, I bought this laptop specifically because it was supposed to have surround sound and it's not working ;-;

Hello, What would one need to play a Dolby Vision UHD Blu-Ray disc on this laptop that has a DV screen? Is it a matter of just waiting for PowerDVD to support DV? What about playing a regular H.265 movie file that has Dolby Vision? Note: for what it's worth, as the laptop has no optical drive it will be a case of playing an .iso of the disc that has been ripped using my desktop PC. The CPU supports SGX. PS: I also read somewhere that Dolby Vision will only be enabled with a future system update, is this still the case? Thanks.

Back in summer I purchased a Thinkpad E550 from Lenovo spanish online shop, still today I don't have what I paid for.Before purchase, I tried confirming the availability of the TPM in the E550 models, after few calls, the only thing I was told is that if website says it has, it definetly has it. So I go on and purchase. On 07-09-2015 I receive confirmation for my purchase via email with all the details including TPM.Laptop was delivered with no TPM (not sure if any other component could be wrong, as I didn't investigate further). After several calls and effort, finally someone accepted that there was an error from Lenovo side and offered a replacement for another model, as E550 has no option of TPM or security chip (be careful when purchasing online using their configurator). They offered me a L540 model as replacement. I cannot consider this model because I don't like its touchpad configuration. I have been using thinkpad machines since IBM and its middle pointer mouse is one of the best features when accompanied by the button on top of touchpad. Anyway, the L540 model was worth around 300eur over the price that I paid for. I believe that that was their target of compensation and I went online and choose a model of the Yoga that was exactly 300 eur difference. They simply said no with no reason. They escalated the case and for my surprise, they accept a yoga as compensation, but they don't accept the configuration that I proposed, in stead they ... Read more

Some won't play any without using an external dvd drive. All have Windows 10 and pretty much the same software installed. They ALL say "DVD Copy Protect: Fail" What's going on? I'm NOT copying them or trying to copy them and they're NOT copied dvds I'm trying to play.

Hi everyone,A few days ago, my ThinkPad went out of battery. I left it plugged to charge it, but could not start it any more in battery mode.When plugged, my laptop works properly, except for the battery which is "plugged in, not charging".I have tried many tips suggested on forums, including removing the battery, starting with and without the battery, updating the whole Lenovo software suite. I could not install any new version of the Battery Manager, since none is available for the E550.Has anyone encountered this problem? Anything to suggest?Cheers,Ben

ThinkPad E550 Type 20DF-004DUS. Thinkpad boots but sceen is black. Sometimes if USB drives or USB connections are removed, the sceen comes on. Sometimes, connecting another screen via VGA cable... the extenal screen comes on. But not always. Here lately, neither the laptop screen nor an external screen comes on. Took it into a shop and they replaced the motherboard... but that did not work so they put the old motherboard back in. They couldn't get either the laptop screen or an external screen to light up with with either motherboard. They tested the laptop screen out of the unit and it worked as expected.Sometimes I get a screen and sometimes I don't.What has me confused is exactly why these problems are happening. Could the cable between the laptop screen and the motherboard be bad? And, if so, could THAT cause the external moniter to be black as well?Have any of you experienced this?

I am using a Thinkpad E550 laptop with 3.0 Ultra Dock. Currently I have my 4K monitor hooked up with Displayport into the Ultra Dock and am only able to reach 4K resolution with 30 hz refresh rate. Unfortunately due to this, there is a lot of "choppyness" in the display, mouse movements, etc. Ideally i need the refresh rate to be at least 60 Hz. Is there a known possibility to get these settings with the current equipment? It seems DP is only capable of outputting 60 Hz refresh rate but the Laptop doesnt have a DP port. I can only get that through the dock. HDMI doesn't seem to do the trick either.

Hello, I have a Thinkpad e550 that I bought last year. Yesterday while typing my term paper I realized that some of the keys(s,k,d) were not working. Then i realized that the entire function keys row wasn't working either. Upon closer investigation I realized that this was because of the fn key always being depressed(not physically). So I went to the BIOS and swapped the control and the fn key. After a reboot I found that all my keys are working, but the fn key(which is now mapped to the ctrl key) isn't. Is there any fix to this? It seems weird that the function key is always depressed when mapped to fn but doesn't work at all when mapped to ctrl. It's been only a week since my warranty expired and I'm hoping to avoid replacing the hardware. Thanks

A:Thinkpad TP E550 How to install Win7 32-bit instea...

The only way would be to buy a 32-bit copy, reformat the hard drive and reinstall Windows from scratch. I am surprised that your 32-bit software will not run, since the 64-bit version of Windows was designed to run 32 and 64 bit software and, in fact, most Windows software is still 32-bit, since not many software manufacturers have have even re-written their software as 64-bit yet.       One the limitations of the 32-bit is that it can only see 4GB of memory (RAM) regardless of how much is installed, so if you are going to run Windows 10, you will probably find it a bit slow.   I have installed programs that were written for Windows 95 for people Windows 10 64-bit.   It requires a bit of tweaking to install and register the older .dll's etc, but it can be done.      What software are you running that cannot run on a 64-bit, and what errors are you getting when you try?   Are you trying to run a 16-bit software application perhaps, because in that case you would not be able to run it in a 64-bit OS environment, as 16-bit emulation was removed.     In that instance, running a virtual machine of a 32-bit version of Windows 7 on 64-bit Windows 10 pro using Microsoft's HyperV, VMWare Player or VirtualBox, would be the way to go.    Virtual machines are pretty cool, and are basically another copy of Windows, Linux or even DOS that runs in a Window of your 64-bit W...

I have a ThinkPad E550 laptop connected to two Acer V246HL monitors via a ThinkPad OneLink Pro dock. One monitor is connected via DVI/HDMI to the dock and the other connected either via VGA or DVI/HDMI directly into the laptop.  When both are connected via DVI/HDMI only one monitor will be detected. When one is connected via VGA both monitors are detected, however the one connected via VGA will flicker or blink off and on. Disconnecting the ThinkPad dock solves this issue. I have tried the following:Uninstalled and reinstalled graphics driversUpdated dock firmwareRun updates on graphics driversChecked different cablesChecked different monitorsChecked different dockChecked different laptopRun Lenovo VGA fix The Lenovo VGA fix would not complete and ended up in error loop. After advice from the internet I unplugged the dock and tried again, but failed. I then unplugged everything but the VGA cable and tried again, but failed. I unplugged all peripherals and tried again, but still failed. Errors include "Invalid AUX device" and"Enable Aux2 Reg Failed".Finally I redownloaded the fix, unblocked everything before unzipping then ran as Administrator, however it all still failed. Any other advice?

I have a Lenovo Thinkpad E550 running Windows 10 having been updated automatically from Windows 7 Pro 64-bit (initial and anniversary).  I cannot get Skype to use the integrated webcam. That is not the issue. Discussions of that said to make sure the video drivers were up-to-date. There have been no non-automatic updates of Lenovo software since its purchase in early 2015. I used Lenovo's utility to identify the system as 20DFCTO1WW. Just about everything looks out of date, so much so I wonder if I am looking at the drivers for the right system though it agrees with the solution center's showing of model and serial number. I am familiar with computers, byut I am not familiar with how Lenovo does things. Multiple questions: 1) The current drivers for the integrated camera are RealTek 6.2.9200.10282 (7/11/2014), but the Lenovo site shows version 6.5.717 (6/19/2016 for Liteon) and Version 10.0.10240.11135 (Bison/Chicony). Is this the same device.2) Is there a suggested sequence for applying multiple updates?3) The Lenovo page has an option "Let Lenovo update your system". Is this safe? Thanks

A:Dolby Advanced Audio Problem after 8.1

I don't have Dolby specific setup, but you might want to check your device manager directly to see if a driver for Dolby appears under the expanded menu as shown below. If so, you can select "update driver" and have it automatically search Window Update or use the latest driver (if you have it handy). I would personally prefer the latter option if available. Good luck.

hi there.
I have Lenovo ideapad S510p and currently running on Windows 10 Pro (64Bit). I upgraded it from Windows 7 Ultimate.
I recently upgraded my Audio driver using device manager on Windows 10 pro. When i first upgraded the audio driver (Around a week ago) Dolby Advanced Audio v2  had gone and instead of it i had Dolby Advanced plus in the RealTek and now again when windows installed update today Dolby Advanced plus is also gone. I didn't update Audio driver today.
I just want to know if Lenovo has removed Dolby Advanced Audio v2 or Dolby Advanced Plus after the recent Windows updated. I never got any error for the audio. I checked in Task Manager,  Device Manager, Program Files, Program Data, App data, etc and i didn't find even a folder of Dolby Advanced Audio v2.P.S. When i upgraded from Windows 7 Ultimate to Windows 10 Pro, I didn't have any problem.
 
Please let me know what has happened to Dolby Advanced Audio v2 and how can i get it back if i want to?
 
I hope i will get a reply soon.
Thanks in Advance.
 
Regards.

Hi Sentient , 
 
 
Welcome to the Community Forums.
 
Everytime Windows update perform its automatic update it would replace current drivers you have and replace it as it sees as more updated version from its own database changing the OEM drivers version to a Microsoft native drivers. 
 
You may try to initially perform system restore before the date windows update occur since it would create a restore date . If you manage to restore older driver version with the Dolby audio then stop automatic updates for the drivers to prevent this from auto changing it .
 
Else moving forward you can also install the audio drivers intended for your model compatible for windows 10 and see if that would be able to restore the dolby enhancements . 
If that fails to restore , you can try versions from Windows 7 and right click to run on compatibility mode.
 
Update us as it goes .
 
Regards
