Lenovo T400 / T500 :: T420s - No Sound Output Via DisplayPort To HDMI Cable
May 26, 2011
I bought a Roline DP to HDMI cable hoping to be able to watch HD content in my livingroom and not having to plug an extra audio cable as DP should carry sound too.
When I do the same as on the youtube video, I get the following settings in the control panels: [URL] ....
But there's no sound coming out of the TV. I've tried it on my SyncMaster PC/TV Screen and on my Samsung TV in the living room. On the TV in the living room, the windows audio manager shows the device, but it cannot be selected as show above. It stays grey.
I've got a T420s with discrete nVidia Optimus graphics (Quadro NVS4200M). Driver version is 1.2.19.0 for nVidia HD-Audio and 8.17.12.6696 for NVS 4200M. This information comes from the device manager. I installed my system from scratch and used ThinkVantage System Update 4.
Where the problem comes from? I could only imagine that the cable isn't capable of carrying audio, but that seems rather illogic, does it?

My problem is that when I'm connected with the t540p to the ultradock that this sound comes from the local speakers instead of through the HDMI cable though the monitor and then through my external speaker which are way better.
In the Sound playback devices I have written: "High definietyion Audio Device Not plugged in".
So I tried connecting directly via laptops mindpoit to the monitor and then it worked. But as soon as I connected it to the docking station which is also connected to the same monitor via DVI plug then it results as Not plugged in.
So I tried upgrading the dock station firmware by downloading the fwdphb03 latest firmware, and this does not launch despite being connected to the docking station and using an external monitor and properly plugged in.

We installed a Kinston 240 GB SSD in the Ultrabay, and it is not fully recognizing the SSD - it does not show up as a device, though we know the machine knows it is there, and we could use Linux and ghost to it..
We then ghosted to it with no issues. We then put it in the main bay, but it would not boot.
We looked at it from the USB port of another computer, and the files looked fine. Are we missing a driver?

Lenovo T420s is randomly crashing. There is nothing special in the Event Viewer. Only that the PC was not turned off properly. Not exactly BSOD.
Error video on YouTube
Usually happening under some load (eg. game) but I have seen the same running only MS Office. No Macros or special calculations.
I would say this happens due to overheating. This is my second T420s I have same problem with. I work as 2nd. lvl IT so I know other colleagues are experiencing the same.
Frequency decreased once performance settings in power management were switched to balanced mode. Not solved though.

I installed Windows 8 x64 recently and installed all the drivers. I was pretty sure that all the devices were installed.I was having a hardware power management problem before installing Windows 8 that I was hoping was a software issue that reinstalling the OS would fix. Turns out it wasn't software, but had to have the main board replaced under warranty. Even after the main board replacement, I was still pretty sure I saw all the device drivers were installed under device manager.
I'm noticing an "unknown device" listed that doesn't have a driver installed. I know often these can be the TPM or other system device, but I have the TPM installed as well as the chipset software and power management driver. But there is still this unknown device.The only clue I have as to what the device could be is under details, the "hardware ids" property value is "rootsscbfs_storlib_bus3". A Google search brings up nothing for this string. "STORLIB" makes it seem like it has something to do with storage, but I have the Intel RST driver (11.7 from Intel) as well as the card reader driver installed. I can confirm the card reader is functioning fine too.

I have a T420s that I bought a couple weeks earlier, it's a used one, so there's no warranty with it, I used it several days without any issue, I don't use it very frequently as I use my corporate one most of the time.
Someday when I wanted to turn it on, it stacks on a black screen and it beeps one beep then two other, nothing showing on the screen not even the thinkpad logo at startup, I thought it was a RAM related issue so I put the one from my corporate PC but without any luck, so I wanted to see if its graphic controller issue, I plug the VGA cable on the laptop and my TV and here I can see the thinkpad startup logo but after that I see a message on the screen telling :
"Real Time Clock Error - Check Date and Time settings. Press Esc to continue or F1 to enter setup" and when I press either one nothing happen at all, still stacks there.

I have a Latitide E6500 with the Nividia Quadro NVS160M graphics card. I'm running Vista Business 32bit. My E6500 vid outs are s-vga and displayport. I use my laptop mainly in my home office and I would like some more real estate, when in the office 1440x900 is just not enough. When looking at monitors displayport does not seem a common input but most have HDMI.
I then looked at monoprice and saw two possible options for displayport -> HDMI, an adapter or a cable. What is the difference between the two and which should I use if I want both audio and video signals transmitted? Or am I stuck using a monitor that has a displayport input?

I have a t420s and so far I'm happy with it.Recently I purchased a MC7700 card from ebay with lenovo FRU. Everything looks smooth except that I found there is no way to turn on the mobile broadband switch.i believe I have a whitelist-removed bios otherwise it won't boot. The driver downloaded from lenovo website is installed fine, I can see the card working in device manager. I could read the iccid in windows network settings. Everything looks good, but I just can't turn mobile broadband on.
My laptop runs windows 8.1, I heard there is a thinkvantage connectivity tool that might work for windows 7 but not windows 8. I have quite a few files on my laptop and going back to windows 7 is the last option I would like to try.

I need to do a recovery on a T420s. I want to recover to same state as out of the box. I already backed up all the data. I am using the disc provided by Lenovo but cannot seem get the disc to start the process. I think I set the DVD as the first boot device but it goes right past it and into the normal start up process.
Is there a way to start the process besides from boot up?

My 5 months old SSD crashed and I replaced it with a Macrium created mirror. Everything seems to work except the computer no longer recognizes USB drives. The USB drives are good (checked on other devices), I've removed and reinstalled all USB hubs and drivers - the chip drivers and bios are up to date and the USBs are enabled in the BIOS AND I've done several virus scans (online and local) in safe mode (Malwarebytes, Spybot, ESET, Defender, AVG, Housecall). The USBs are recognized on boot but once Win7 boots the USB for storage devices no longer work.... however, the USB recognize keyboards and the mouse. Guessing a new OS install will fix it, however, I would rather not reinstall everything.

I have been running ubuntu on my T420s for about 2 years now. Needed a Windows box to work from home so I installed Windows 7 Home Premium - Service Pack 1 on it. Installation went smooth but Windows did not recognize my wireless card, preventing me from connecting to the internet to download and install the rest of my drivers. I tried to manually install the Intel Wireless Lan (bg, abg, abgn) for Windows (64-bit) Centrino Advanced-N 6205 which is what I thought was installed on my machine to no avail.

I have a Lenovo t420s with dualboot win7 and Ubuntu. I never had any problems until now and could switch on/off my wireless and bluetooth connections via the Hardware Switch (right bottom left of the notebook) or via FN + F5.
However, without any specific reason the wireless and bluetooth was switched off and the the system tells me that I have to switch on WIFI via the Wireless Radio Switch. However, although I can move it, it doesn't make any difference for the Switch.
I tried to reset the BIOS to Default and changed the network settings, and also rebooted several times. I won't work with any of the two systems.

My U330P is running Windows 7 with the latest drivers for both the Intel HD video module and the Realtek audio chip. I would like to connect my machine to a TV via HDMI and have it both act both as the display as well as the audio playback device (i.e. TV speakers should blare, not the ones in my Ideapad).
The thing is, I don't have said TV yet and if what I want to do is not possible, I will not bother buying it. I already did look around in Control Panel -> Sound -> Playback in order to find out whether there's an option to set the HDMI port as a playback device but found nothing. I also have the playback devices menu display disconnected and deactivated devices, but the only thing showing is the built-in stereo speakers. The listings in my device manager don't suggest something like a "digital sound whatnot" either.
So in general whether the audio signal can be rerouted to the HDMI output connector on a U330P.

I was watching a film on my projector, from my Lenovo T510 laptop, using a Display Port to HDMI cable. There was a thunderstorm and a powercut during the film, but my laptop wasnt plugged in at the time. Then when I touched the Display port end of the cable, which is plugged in to my laptop, it was too hot to touch, and had was slightly bulging and mis shapen! Now it has cooled down and just looks and feels normal. Very strange, and I dont see how it could have been related to the storm and powercut, but it seems a bit too coincidental! I have used this cable multiple times before and never noticed this, but then again maybe I wouldnt have ever touched it until it had cooled down. But I it was pretty much metling it was so hot, so I would think Id notice it.

I have recieved at work a lenovo t440 notebook, everything worked fine, untill one day I noticed that I cannot conect to the internet via lan cable. I plug in the cable and it is not detected. I checked the cable to another notebook and it was working. I have a Intel Ethernet Connection I218-LM controller, I have re-installed both network drivers from lenovo and intel websites and nothing works. I've tried as well to get automatically from windows update, no result. Went to bios cheked if the lan connection is enabled, everything was in place. Is there anything I missed? I noticed a weird behaviour, if I connect through wireless network, after sometime the lan connection is established and I can use it, but without wireless connection it doesn't work.

I bought this computer which is running 7win64 to update my T60 which I use with my home TV, a samsung digital running at 1360x768 resolution. The computer's native resolution is 1920x1080. I bought an hdmi adapter for the displayport from lenovo when I ordered the computer. Initially, the display works and at first it ran long enough to get everything set for a nice crisp display that fits the screen perfectly. The sound is there too, and is passed on to my receiver by the TV. Very nice. But then it begins to blink off until it doesn't work at all (the sound is cut off too). Lately it won't stay on long enough to review settings.
All updates are in place, both from microsoft and from lenovo. This has Intel 4600 graphics built in, and intel has graphics drivers available, but won't install them because of the lenovo supplied drivers.
I can't get any support from lenovo support because another device is involved.
I read online of some early users who had this problem with a docking station and i guess the problem was resolved with an updated driver.

Sound has busted on T520 for a few weeks now. I can hear sound when I plug in my earphones, but windows recognizes this as a speaker, conexant 20672. I checked the "find and fix audio playback problems" in windows 7 to no avail. I believe I may have to have my speakers repaired. I am still under base warranty until sometime next year.

I have a Sony Vaio 17 inch full HDMI laptop using Vista. I have been using a HDMI cable connected to my TV for a few months now all working fine yet today for no apparent reason the sound has started coming through my laptop rather than the TV. I have gone to the control panel and tried switching the default sound to the realtec digital however this did not work and I ended up with no sound at all.I have tried two different players both VLC and Zoom player.

Yesterday I bought a little 22" Vizio VW22L television to use as another monitor for my W530. I'm using this cable: [URL] to connect my computer to the TV. When I connected it at first it worked fine for about 45 minutes then I just got screen noise (short, multicolored vertical bars moving everywhere). Now whenever I try connecting it I get my computer's display on the TV for a couple minutes, then the screen noise again.
I was wondering what the issue is or could be. The cable seems to work fine. I tested it with a Magnavox television and a different Vizio TV. This TV's HDMI port also seems to work fine. I had my brother connect his Samsung Series 3 to it via HDMI and it ran perfectly well. The Lenovo update utility says all my drivers are up to date, as does Windows update.

The sound is failing intermittently on my T430.
Closing then opening the lid to enter and return from hibernation sometimes restores sound. When this does not work restarting the machine usually restores sound. But the sound fails again after an indeterminate period.
Opening Ubuntu Linux in Virtualbox now displays the message "Some audio devices (PCM_in, PCM-mic) could not be opened".

just got a T430s with i7-3520M processor (3.60 GHz, 4MB L3, 1600MHz FSB) and 8G memory. How do I stream to my HDTV with sound? USB 3.0 to HDMI adapter? MiniDisplay to HDMI? Any caveats I should be aware of?

My 3 month old t430s has a major issue with the audio/sound. At completely random times, I will have no sound for a matter of minutes or hours. This is primarily with web software and persists across multiple browsers.
- The speakers all test and the troubleshooting tests say they are working just fine. Occasionally, when testing the speakers, the control panel will give an error stating that they are in use by another program and that program needs to be shut down before they can be tested.
- all drivers are up to date and have recently been uninstalled and reinstalled
- the default audio device is set to the appropriate speakers
- I have had this problem with and without the Dolby Advanced Equalizer driver that comes as an optional sound update
- I have had sporadic luck with plugging in headphones, but often this does not give me any audio either.

I just received a new T430 less than a week ago, and ever since I first handled it, the left palmrest has been making clicking/snapping sounds even under light pressure. This region of the palmrest appears to be above the SmartCard reader. Video of this phenomenon is below.
