Lenovo T400 / T500 :: No Option To Disable Touchpad When External Mouse Is Connected To T440p

Nov 8, 2014

New ThinkPad T440p and the first issue I encountered is there is no option to disable the touchpad when an external mouse is detected. I don't want to do it via the bios or some other hack as I use the touchpad when it is not convenient to use an external mouse. So it should be able to do the switching as needed, this is a simple feature that other manufacturers have had for years and years. 
I already upgrade the UltraNav Driver to the latest v18.0.7.57 and that didn’t present a solution. I am running Windows 7 SP1 - 64bit.

Lenovo T400 / T500 :: Dual External Monitors Without A Dock On T440p?

Mar 15, 2009

Is it possible to use two external monitors with my T440p (20AW-A08500) with Intel HD Graphics withou having to buy a dock? I normally use my laptop at home with the lid shut and two monitors attached.
I used to have X1 (still do - now up for sale) and that was happily connected to two monitors via HDMI and via a MiniDP to DVI adaptor.I wrongly assume when I bought the T440p that I would be able to somehow power my existing two monitors from the single MiniDP port.I have seen their is a Lenovo DisplayPort to DualDisplayPort adaptor - but this talks about ThinkCentre usage - no mention of Thinkpads. Plus the price of this adaptor is pretty steep.

Lenovo T400 / T500 :: T440p - External Displays Via Ultra Dock (occasional Flicker)

Dec 23, 2013

We have 2 new T440p (i7 4800MQ, 16gb, ssd) which we installed with clean Win 8.1 and the newest drivers (intel hd, nvidia

The laptops run on 4 ultra docks with different monitor configurations, mostly dual display, one single display, mostly samsung displays, always one display via dvi, second displays vga as we did not receive our display-port adapters yet).

In all configurations we have the same problem: Between every few seconds and about 20 minutes the external screens flicker and get rediscovered. Often this happens in Chrome or when doing some graphic-intensive stuff, but we cannot trace it down. Takes a few seconds to rediscover and all windows not in fullscreen are resized afterwards, because of display resolution detection and mostly we get the Display port new topology notification... We already tried with disabling the nvidia via the nvidia gpu settings and only using hd graphics but that didn't work.
A few years ago I had problems with my T400 discrete grafics, but then I could disable it in the BIOS which does not seem to be possible with the T440p...

Lenovo T400 / T500 :: Losing WiFi Connection And (external) Screen Flickering On T440p

Jan 27, 2013

This is a brand new TP T440p and I installed a fresh copy of Windows 8.1 Pro on it (licenced). I've applied all Windows updates and installed all drivers/BIOS updates from Lenovo System Update.
The computer works fine, but when I put it to sleep and wake it back up, the external monitor is almost always flickering (there is a 1mm movement to left and right, line by line - I'll shoot a video, if the camera will be able to capture the movement, because it's very "fine"). Sometimes it stops after a few minutes, but most of the time I need to re-boot the computer.
Also, not always, but many times the WiFi connection is lost and I can't reconnect unless I reboot the computer.

Lenovo T400 / T500 :: T431s Left Mouse Click Does Not Work When Disable Trackpad For Cursor Movement

Jun 3, 2013

As a confirmed trackpoint user, having the mouse built into the trackpad of the T431s is causing me all sort of grief, including sore wrists - but there are two problems I can't seem to diagnose.

1)  When clicking the pad for left mouse click, it often does not work until I click it a few times.  I notice this more when I disable the trackpad for cursor movement (which I had to do because the cursor moves when I try to click) - but its there even when that is enabled.  It comes and goes.  I guess there could be some foot trapped in there, but I've only had it a week and been pretty careful.  I'd rather not learn to remove the keyboard on day 6.  

2) The right click gets into a condition where, when browsing,a click brings up a new tab of the link I clicked on, rather than showing me the options (open in new tab, incognito window, save link, etc).  If I connect a real mouse, it is normal.

Lenovo T400 / T500 :: T440p / How Many USB3 Ports

Nov 7, 2013

according to the lenovo US site every T440p will come with 4xUSB3 as standard:
The psref´s (WE for western europe, but also the worldwide) say it will come with 2xUSB3 and 2xUSB2:

All 440p you can order here in Germany unfortunately seem to have 2xUSB3 only. 
This is very confusing. Why sould lenovo buy/develop a 2xUSB2 version (USB3 is fully downwards compatible) ?

Lenovo T440p T400 / T500 :: Using Function Keys In Applications?

Jul 17, 2014

Just got a T440p and it's working fine.  BUT when I go into an application like Word and either hit the function key or combine it with the Alt, Ctrl, or Shift key, I still get the default action of the Funciton key.  For example, in Word, the Alt-F9 combination is used to display field codes.  When I do that, however, I get the Control Panel popup.  Similarly, in a browser, I should be able to hit the F12 key and get the Developers pane at the bottom of the screen.  But instead in IE, Chrome, and Firefox, I get a My Computer popup.

Lenovo T400 / T500 :: T440p / Determining The Right Thinkpad Dock?

Jan 13, 2015

I just got myself a thinpad T440p and was planning on getting a docking station. Since i have never gotten one before i was confused on which one should i get. I wanted to get the thinkpad Ultra Dock but was confused on how i would determine if i should be getting the 90W, 135W or the 170W. I live in Canada, Ontario if it makes a difference.
I was also curious, whats the main difference between the basic dock and ultra dock. Is it worth it for me to get the ultra for work?

This suggests that OPTIMUS technology is not switching the graphic card properly. System running on windows 8.1 Pro 64bit. How to enable Optimus switching?

Lenovo T400 / T500 :: T440P - USB Boot UBCD4WIN Cannot See Hard Drive

Nov 25, 2014

IBM/Lenovo laptops and desktops for a long time. I recently purchased a T440P laptop with a standard 7200 RPM HDD in it. In the past, with previus models, when I wanted to troubleshoot the current Windows install (virus infections etc) I would use UBCD4WIN on a USB stick to boot the computer to USB and access the hard drive to pull data off or remove files infections etc. With this new T440P I cannot seem to see the hard drive when I boot it up with the USB stick.

I can boot the computer just fine and run the USB based OS without trouble but I simply cannot see the hard drive.

So far I have tried:
-Adjusting UEFI to Legacy and/or "Both"
-Adjusted CSM to Yes and No
-Disabled/Enabled Secure Boot

and several combinations of all of the above in hopes it was the issue but it doesn't seem to change my ability to see the hard drive. It simply doesn't show up.

The drive itself (in the T440P) is a standard HDD (not SSD) and is formatted NTFS with Windows 7 64bit installed on it.. The UBCD4WIN is a basic "Windows XP" x86 (32 bit) OS on a USB stick and the USB stick is formatted FAT32.
In previous lenovo models (T400/T410 etc) all I had to do was switch AHCI to Compatibility and I could see the drive but this one is giving me a real fit and I am not exactly sure if its a controller driver, UEFI or something else.
how to see the hard drive when booting to the USB UBCD4WIN stick?

Lenovo T400 / T500 :: T440p - Right Click Shortcut / Possible To Switch Primary Function Of F Row

Oct 16, 2014

I have the Lenovo T440p model.
First is while I'm docked in at work I use a normal key board and it has a right click botton on it. When I go home I do not have that button and know for previous models there is a short cut that you can do to "right click" rather than going to the track pad and right clicking. 
Second is for the F1, F2, F3, etc... to work I have to hold down the Fn button. Is there a way to turn around the keys to where when I hold down the Fn key and press F1 it actually mutes the sound. I guess im trying to say is there a way to switch the primary function of the F row?

Lenovo T400 / T500 :: T440P Crashing When Sharing Desktop - Intel Driver

Feb 18, 2013

After updating to the latest video drivers from the ThinkVantage Update Retriever, our Lync clients crash when sharing desktop on our T440P series and X240 series.  I noticed when I uninstall the video driver I am able to screen share without incident.  Also, if I update the driver from Windows Update I am able to share successfully.  We use the update retriever and thininstaller to install our drivers in our environment.  I have tried uninstalling the Lync updates all the way down to the base version and experience the same issue at every level.  It crashes 100% of the time when sharing desktop.  I have tested it on T440p machines in our environment that do not have the latest display driver, and no crashes occurred.  Here are the specifics:
Thinkpad X240 [20AL]
Thinkpad T440p [20AN]
ThinkVantage Update Retriever 5.00.0007
Thinkvantage Thin Installer 1.2.0010
Intel HD Graphics Driver - gid634ww (
Microsoft Lync 2013 SP1 32 Bit (15.0.4569.1503)

Lenovo T440p T400 / T500 :: Ericsson N5321gw Doesn't Recognize SIM-Card?

my new T440p with built-in WWAN Ericsson N5321gw doesn't recognize the SIM-Card. I'm running Win7 64 Bit and in the device manager, I can see the Ericsson device showing up without any errors. Once I launche Access Connections, I receive the error message there's no SIM card inserted and I should insert the SIM and try again. The SIM is inserted as shown next to the slot (although I tried other ways, too). I tried two different SIM-cards just to be safe, both SIM-cards are working in my phone.

Lenovo T400 / T500 :: T440p Hotkey Integration Driver Fail - Win7 X64

Sep 9, 2014

Brand new T440p laptop out of the box.
Imaged with preconfigured company Windows 7 x64 image I have used hundreds of times before via MDT. WDS packaged T440p drivers (downloaded from Lenovo website) are injected as part of the MDT installation process.
All windows updates applied (except for the Lenovo PM Device Driver otherwise the thing no longer reboots or shuts down properly anymore) BIOS flashed to latest T440p revision.
Run Lenovo System Update to install hotkey drivers and receive the following:

As you can see Win7 x64... driver says no.

Restarted and tried again... error.
Tried downloading the driver manually from [URL] .... Same error.
Searched for and downloaded version 5.40 .... Same error.
I ran Lenovo System Update 2 days ago on another T440p laptop, may have been a slightly different internal spec... not sure but I'm fairly sure the driver was named differently in System Update. The driver Installed on that machine fine and functions as intended.
The driver could very well could have been updated since then I guess. I do also know this is a newer batch of T440p's as the box configuration that it ships in has changed and looks completely different.

Lenovo T400 / T500 :: T440p Screen Slightly Adjusting Brightness On Google Chrome

Jun 24, 2014

My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.

Lenovo T400 / T500 :: T440p - Audio Coming From Speakers Despite Headphone Being Plugged Into Jack

This doesn't always happen, but I've noticed a few times on my T440p that when I have headphones plugged in, sounds comes out of the speakers. The headphones are functional and fully plugged in, yet no sound comes out of them, and the sound comes out of the speakers. I've fixed this multiple times by unplugging the headphones and plugging them back in.

Lenovo T400 / T500 :: T440p / Windows 7 - Fingerprint Reader Fails On First Attempt To Log In But Works On Second After Delay

Jan 7, 2012

I have a T440p with Windows 7 Pro.  Except on rare occasions, I am unable to log into Windows with my first swipe across the fingerprint reader.   The green light is on when I do the first swipe and it immediately goes off and stays off for around 15 seconds, during which time another swipe does nothing.  Then the green light will return and a second finger swipe will log me on.
It's made using the fingerprint reader for login impractical, because it's faster to just go to the password screen and log in that way. 

Thinkpad T440p: i7-4800MQ | Crucial 16GB DDR3-1600, 9-9-9-24 | Samsung 840 Evo 500GB SSD | Intel 7260 Dual-Band AC Wireless | Windows 7 Pro
