Lenovo T400 / T500 :: How To Use NVidia Graphics On T430
Sep 9, 2013
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

When I'm using any aplication with Nvidia card (Photoshop, 3D Max, etc.) or switching to external monitor (Display Port) my CPU sets down to minimal values: 1.15Ghz.
This issue very important for me, because working on such speed is impossible ....

I have a T430 with i7+ nvidia nvs 5400M.
I upgraded to 8.1, everything went smoothly, installed the drivers from lenovo update and windows update. At random times, typically when I play flash content or use metro apps, explorer.exe crashes, windows try to restart it and it goes an infinite loop with flashing screen. I can stop it only by cold reboot, which leads to work loss.
The event viewer showed ntdll.dll related error in explorer.exe and iexplorer.exe, and after contacting microsoft support, they checked my dump files and we found that it was nvidia driver related problem specifically :
FAILURE_BUCKET_ID: NULL_CLASS_PTR_WRITE_c0000005_nvumdshimx.dll!Unknown.
I installed versions 320.92, 326.19, 327.23 and none of them work.
If I try to install the latest lenovo windows 8 version of the driver, i get black screen after the windows boot screen.
So I am in a situation that nvidia support tells me to contact lenovo, lenovo support told me that despite this windows 8.1 compatibility list [URL] , they do not support windows 8.1, and I should contact Microsoft, and of course Microsoft tells me that they are not in charge of developing graphic drivers (true).
I cannot work on my laptop since it is crashing every 30 minutes or so, and I don't want to rollback to windows 7. What should I do?

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.

bought my T430 this week.
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:
WARNING: CSerializationHelper:: InitSerialize failed : 0x80070002
Going into Event Viewer gives the equally cryptic "English ESD Bundle Parent" as a possible cause for the failure.
SFC and chkdsk do not report anything out of the ordinary.

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 have the latest audio driver...

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.".

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".

I know that the T430 equiped with nVidia graphics is capable of supporting more than 2 monitors.
What about T430 equipped with the HD4000 graphics Card, using the MiniDock Series 3?
I have connected three monitors (Dock-DVI, Dock-VGA, ThinkPad-MiniDisplayPort) but, so far, I can extend my desktop over two of these three monitors only.

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.

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.

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 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 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.

I've owned a ThinkPad T430 for about one year now. Originally I was fairly impressed with the battery life (around 4.5 hours) but now after owning it for a year I am very unimpressed with it's short 3 hour life now.
I have read that batteries should be expected to do this, although I have friends with a MacBook Pro which has lost maybe 20% of it's charge over three years not one year like my ThinkPad!
My specs are listed below:
OS: Windows 8 (upgraded from 7)
Ram: 8GB (4*2 DIMM - came with 4GB and I upgrade it with 4 more)
CPU: i5-3210M 2.5GHZ
Hard Drive: Samsung 840 Pro 256GB SSD (upgraded from the 320GB 7200RPM HDD before...if I have got those specs right)
I recently installed the new SSD and expected to see my battery life shoot up again (hopefully at least half an hour) but I really haven't noticed any such improvement.
I use the battery frequently for school and run the battery down to about 20% maybe twice a week on school weeks?
Is this kind of deterioration to be expected and should I simply purchase a new battery if I need that extra 1.5 hours?
According to the Windows 8 battery report the original full charge capacity was: 49,286 mWh, now it is: 39,780 mWh.

Replacing the stock mSATA SSD used for caching on the T430 with a large capacity SSD and placing an OS on it?
I've got a T430 with dual boot Windows 8.1 and Ubuntu. I rarely use the Window partition, and I want leave it on the HD and migrate the Ubuntu partition over to a new mSATA SSD installed in slot currently used for caching for Windows. I'm not concerned about Windows slowing down without the cache, but I do need a bootable windows partition.
I was about to go ahead and purchase a suitable mSATA SSD for this process when I read the hardware maintenance manual (pg 26) and mSATA update guide, which made me think that using the mSATA for anything but caching on the T430 might be problematic.
