Lenovo T430 T400 / T500 :: Audio Over Display Port?
Feb 3, 2014
I wanted to go today and get an adapter for my Lenovo Thinkpad T430 and first I thought I should do some research. This is how I found out that most of the Thinkpads do not send audio over DP, as I would have expected.
I have the T430 (no discrete graphics, just the integrated one) and Mini Dock Series 3 with USB 3.0 (EU1) docking station. The laptop has mini-DP and the docking has a normal DP. The normal DP works fine with my monitor, but it doesn't have any speakers in it , so can't test the audio part.
I checked in Audio properties in Windows (7 x64) and I don't see the video card there, so I am assuming it is not supported. I don't want to buy adapters if the laptop is unable to send audio over a DP-> HDMI adapter.
I have a brand new TV with USB, RS232, HDMI connections and of course with a screen in16:9 aspect ratio. I want to use my existing RS232 cable to connect my T430 to the TV and display videos/movies that I want to view with others. HOWEVER, the video output always gets a black bar top and bottom from the T430 when the TV is connected. As a result, the image is stretched side-to-side both on the TV and on the T430 simultaneously showing the video. It is ugly. If I watch a movie in the very wide movie format 2.35:1, the bars are of course even larger and the movie is simply unwatchable it's so thin, top-to-bottom.
This is true regardless of the video source on the T430, either a movie via VLC or MediaPlayer off the hard drive, or streaming.
Two odd things: it does not happen if I play a movie on the TV directly from a USB key - it has a USB port and that works just fine. Also, if I simply unplug the RS232 from the TV then everything gets restored and the image on the T430 is perfect without any bars top and bottom.
In summary, a 16:9 video source connected to a 16:9 TV via RS232 is given black bars top and bottom, and there is no control on the TV that can correct this (TV has two settings for RS232 display, 4:3 and 16:9. 4:3 actually displays the 16:9 ratio correctly, but with a large black frame around it. And 16:9, the "auto" setting, gives the problem above).
So I have two questions:
1. Is there a setting on the T430 that I can adjust to resolve this issue so that the black bars are suppressed for 16:9 video replay?
2. If I switch to using the more expensive T430 minidisplay output (via an HDMI adapter) and connect that way, is it likely to fix this issue? I don't want to go to the expense of the adapter and HDMI cable if it will give essentially the same result.
This only applies to videos. That is, when I close down the video, the 16:9 desktop that shows on the TV is identical to that on the T430 and aspect ratio is not squished on either display.
So it's something to do with how the machine sends out the video streams via RS232 that's screwed up somehow.
The sound quality is junk its as if i am listening to a really low quality audio file all the time this is through the headphone jack. I cant find any settings to fix this in the drivers and if i use a 3rd party eq such as in vlc player it just gets worse.
If I turn the master down to 10% and turn up 3rd party volume the signal distorts at 50% signal on the 3rd party hard core.
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 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.
I'm an owner of T430. I have toshiba hitachi 500gb and mini ssd 16gb running windows 7
Right now as I was working on an assignment i got a Microsoft Warning that my Hard drive was failing and that i have to run a back up (which I am doing right now)
Never had this problem and I've been using computer for awhile now and it's my first time seeing the warning window. Is there a way to see if this is a "real" problem? is it caused by viruses? and is it covered by my warranty?
I just ran lenovo solution center hard ware scan and passed everything except my mini ssd. with a code WHD00D001-UI4W8F.
So it seems like my hard drive is working fine, I had some problems with hardware scan failing my mini ssd before.
My new T430 has both the built-in Intel and NVidia graphics controller (see system specs below). Question: how do I switch to the NVidia controller? I can open both the NVidia and Intel control panels, but for the internal (laptop LCD) display I don't see any way to enable the NVidia controller.
System specs ============= Microsoft Windows 7 Professional x64 THINKPAD-T430 Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz Memory (RAM) 8.00 GB Intel(R) HD Graphics 4000 NVIDIA NVS 5400M
after installing every software i will need on my notebook, i closed it (sleeping) and put it in my backpack. i only needed it again after 2 days. when i touched the bag it was already hot in the outside, i opened it, and my Lenovo was burning... i turned my computer on, the battery went down to 13% from 100% (2 days ago), as it was sleeping, i would have suggested it uses roughly 10-15% in 2 days.
my questions are: 1. is the heating thing normal while sleeping? what could have caused the problem? 2. is it possible that some parts of the computer got damaged in such a hot atmosphere? (note that i kept it in a closed bag)
possible solution to question 1: i ran a command prompts, typed in the code that tells me what is allowed to wake my computer. noticed the external Logitec mouse and that Intel giganet networks were allowed, so i disabled both. it was probably the mouse as it was in the same bag, i guess it was moving in the bag and waking the computer?
I have a T430 (2342-CTO) with an i7-3520M processor that I purchased at the beginning of 2013, and I loaded Virtualbox along with an appliance. When I ran the appliance, it gave me an error something to the effect that virtualization is unavailable on my machine.I went into the BIOS and found the settings for dynamic frequency and hyperthreading for the CPU, but I didn't see any entry for virtualization - where to look or what to do to enable this feature?
I am in the process of changing from a Crucial 256GB M4 SATA SSD to a Crucial 240GB M500 SSD. (I'm unable to upgrade the M4 firmware as laptop has UEFI BIOS). I have imaged the M4 to an HDD and find that the C: partition is 12% defragmented and the recovery partition Q: is 99% defragmented. I have a Lenovo T430s laptop running Windows 7 Professional. Should I defrag both partitions before installing the new SSD, or not bother? Also the Q partition had only 2GB free on the M4. Should I increase this when I change to the M500?
I've been having this weird problem where my Fn+F5 combination (which toggles wireless on and off) has stopped working. I recently uninstalled, and then reinstalled, the lenovo driver for power management in windows 8 64, because I was having the same problem with putting the computer into sleep mode via Fn+F4 (I think by reinstalling the driver, it fixed the sleep mode problem but screwed up my "toggle wireless" ability via keyboard). If the power management driver was potentially the culprit for these two problems, and I reinstall it once again....
I cannot install Windows 8.1. I have a T430. I go into the app store, start installing 8.1, it downloads, starts installing, and fails just after that point -- at 54% -- with the error message 0x80070002. That apparently means "File not found", but the Windows Update logs don't point to which file is not found, only giving:
I have got a problem with my T430. I'm not able to boot from usb stick. I checked BIOS settings like 1000 times. Approx. 8mo ago I installed an Ubuntu form usb stick, and everything went well. But now, I guess after BIOS update (2.54 or 2.56) it doesn't work any longer. Today I saw on support webpage information about BIOS version 2.57. It has even written that it solves my problem: "Fix an issue where the system fail to boot from USB device by configuration.".
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".

I know the Intel 4000 video can only handle dual video, but is there any way have both those streams on external monitors. I have one that is extended and I would like to use another port to simply passthrough the interal display signal. I am using the series 3 miniport plus which has two digital/dvi ports and a vga out. In connecting to the second digital or the vga I get no signal. Likewise with the side VGA on the PC. I wouldn't even mind if the laptop display stayed lit as long as I could see it duplicated on a real monitor AND KEEP MY EXTENDED DESKTOP on another extenal monitor.
Seems like an obvious feature for a docking station.
After using for about 12 months my Lenovo T430 2349-GRS without problems, the fan started working loudly all the time I have turned on the PC (all working day from Monday to Friday, T430 connected to the powersupply/charger).
I used the tool HWINFO64 to monitor the temperature and fan speed and realized that the motherboard temperature is working continuously all day above 65°C, and the fan speed is above 3800rpm, so it becomes very noisy.
Then I realized that if I unplug the power supply from the T430, in a few seconds the noise goes, and the computer become silent again.
Below is the image with HWINFO64 log results, in green you will see the T430 with the power supply UNPLUGGED, and in yellow when I connected the power supply.
In the last column of the image, you will see the fan speed in RPMs.
Is there any way to solve this? The fan is very noise above 3800rpm.
I have a T430 that is a couple of months old. I've had this problem from the very beginning. Decents specs (have a Dell laptop with same specs and it never has this issue).
Processor: Intel Core i5-3320M CPU @ 2.60 GHz RAM: 4GB
Basically, after every time the laptop is in sleep mode for more than 30 minutes, once I open up the laptop and log in, there is a period of 3-4 minutes where it is EXTREMELY slow. The computer lags ridiculously...
I have multiple T430's at my company that are slow to shutdown. It takes approximately 10 minutes to shutdown. It is also consistant, as soon as you login and shut down it will take that long. These are all installed using an image. Running windows 7 64 bit. Looked in event log, but no indication of abnormal errors. Using Kaspersky, Office 2010, Mozy. Checked some registery settings on microsofts website but that didn't fix the issue either. Not sure if this is a lenovo problem, or a windows problem or a conflict with other software.
I just bought ThinkPad T430 and optical bay adapter IB-AC642 [URL] for my ssd 128 OCZ VERTEX 4. I put ssd into optical bay but thinkpad doesn't recognize it. I try with different disc but I have the same problem.
My optical bay adapter with this sdd OCZ VERTEX 4 is working in my another laptop so the problem is only with thinkpad. I tried to change bios settings but it didn't work.
I currently am doing IT work for a remote co-worker and he said that his T430 only came with Lenovo Recovery discs and that he doesn't have any standalone Microsoft Office discs. Is there a download for the Microsoft Office Home and Business 2010 version that he's using that I can download to his machine, so I don't have to use the recovery discs for a factory reset?
I tried going to Microsoft's site to get the 2010 version, but when I entered his key, it said that there's no download available for the OEM version of Office 2010.
I have a new Thinkpad T430 and I have an issue with the touchpad. My touchpad is disabled while holding a key on the keyboard which is extremely frustrating. If I hold down a key then my pointer will move a short distance before stopping and becoming unable to move any further until I release the key. I've learned that this feature is know as the palmcheck feature of the ultranav drivers. However, in the settings for my touchpad, there is no palmcheck setting. The feature seems to simply be on with no option to turn it off. I have updated to the latest drivers, but still there seems to be nothing I can do to fix this issue.
I have a new SSD I'd like to use in my T430. Unfortunately I can't install Windows on it as the laptop doesn't recognise (?) the SSD. Before the installation starts I get the message "PXE-E61: Media test failure, check cable".
I tried updating the BIOS but the situation stays the same.
