T440s - LG or AUO Display

Q: T440s - LG or AUO Display

Dear Users, Since a few moments I am a (happy) owner of Lenovo?s new and business class model T440s. As I could find out, Lenovo is building in two different displays. On the one hand there are several model with aLG-DisplayModel: LP140WF1 (sp)(k1)P/N: 0C00349FRU: 04X0626 And the other from AUOModel: AUO B140HAN01.2FRU: 04X0436 (You can look up your displaymodel via BIOS, Everest or any related program) As far as I could find out in the world wide web there are several users reporting with a LG Display in their T440s that it is in quality inferior to the AUO Display. It seems that Lenovo is ready to replace the LG with an AUO display, sending out a tech. My question is what your experiences are and what can we, the owner of a LG-Display, do?Is there a real quality gap between these two types of Display? My T440s, as i mentioned, has a LG Display. I can live with this one, if there are no great difference in the quality to the AUO Display. I am excited about your opinions.Thanks Fire

Preferred Solution: T440s - LG or AUO Display

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Don't sweat it. Both are absolutey huge upgrades over the TN panel. While the AUO is a bit better, its not worth the trouble. I have both and I like both. I did a compare on the same thread u heard about the issue.

Hi All, I have a T440s in an Ultradock with the monitor closed and three external monitors connected (1 HDMI, 1 DVI, 1 VGA). Everytime that i undock the laptop and open the display, the display stays black.  This doesn't seem to happen if i put the laptop to Sleep, undock the laptop, and then turn the machine back on.  The only solution after undocked is to do a hard shut-off (losing any open data) and then turn the laptop back on. I've used the Lenovo Updates and Drivers application as well as the support website to validate that the Intel HD Graphics drivers are on the latest version. Any help is appreciated!

Hello,  I own a Lenovo Thinkpad T440s. While it was still under warranty (about 1month left) i contacted Lenovo support for a screen replacement.

I've been having some issues with dual display with a T440s and a 40A2009US Ultra Dock. OS is Windows 7 64 Enterprise. I two identical Dell LCDs connected to the dock. One via VGA and the other DVI. Both displays are being mirrored and I can't seem to change it. There is only one monitor listed in Device manager.Both external monitors will only display an image if the PC is started closed from the docking station power button. Removing the laptop and replacing it on the docking station does not wake the monitors and there is no image until the laptop is manually shutdown and restarted. I have updated graphics drivers, as well as any driver related to the dock (USB3.0 etc). I have tried a displayport to DVI connector as well, no go. After some research I discovered the firmare may need to be updated. The synaptics package from the lenovo support downloads site gave me the message that my firmware was already up to date. The other fwdphb06.exe that is recommended elsewhere would not update. When I double-click the package there is no install prompt or process being run. There is an external monitor connected to the dock. I have swapped the dock for another, as well as the power supplies for each. I'm stumped. Any idea what my issue may be?

I applied the "critical" Intel WLAN 7260 driver update 20.50.1 (aka 18.33.12.2) offered by Lenovo System Update to my T440s running Win 10 1709 Pro 64-bit. I have two monitors (built-in and external, with the external one positioned above). After the update, in certain applications running in the top (external) monitor, when I drag a vertical divider,  it caused vertical lines to be rendered on the lower, built-in monitor. Those lines are low-quality replicas of the region that the divider is passing over in the upper monitor. (See left part of image) Rolling back the driver to 18.33.11.2 fixed the problem.  (The WLAN driver rollback fixed the display problem!)  I can live without this WLAN update as there are no security fixes listed. So far it is only software from National Instruments that exhibits this issue.  So no crisis. But:Why does the WLAN driver mess up my display?Is anyone else having issues with this driver update?The update seems to only be related to new ETSI requirements (here). Should I care?Thanks!

Hi there.I'm new here but old to IBM/Lenovo  I'm writing you because I'm experiencing a challenge with my t440s and I'm getting crazy.About one month ago, I performed a clean reinstall of Windows 7 pro on my t440s, also installing all the most updated drivers from Lenovo support website (in particular the power manager, hotkeys, display drivers, etc... Nowmy battery duration, with the same power manager settings, has dropped from an average duration of 5 hours to around 1:30-2 h. (normal websites browsing, email checking, nothing "too much"). I have performed a battery reset in the battery management section of the power manager, but nothing changed.When the display brightness is set to 0, the screen is actually still on (not so bright) but still on, and it's a way too much for me if I use my t440s during the night time. Before reinstalling the OS, setting the display brightness to 0 = black screen, like switched off. Hope someone can help me with this situation.Thanks a lot and wish you all a super weekend.Andrea

A:VERY DIM SCREEN ON T440S

Make sure drivers are updated and not using a generic VGA driver. This would make the dock not work and not be able to adjust screen brightness. If it is to the point where you can hardly see it at all then it most likely is a bad screen.

Apologies if this question has been previously answered.  I searched and couldn't find a response.   I'm still using the original HDD that came with the laptop.  I'm thinking of upgrading to an SSD and cloning the HDD to the SSD.  My question is what to do, if anything, with the, M.2 16gb cache that came with the laptop.  Should this drive be left alone as is in the laptop after the HDD to SSD upgrade?  Should it be removed?  Should anything be done to the M.2 drive if I upgrade the HDD?  My understanding is it currently speeds up the computer at start-up and with an SSD, this wouldn't be all that necessary.   I appreciate everyone's time.  Thank you.   -Rich

Welcome to the forum!
 
The 4GB slot is soldered to the motherboard, so you have only one slot free, meaning max RAM stays on 12GB (4GB soldered + 8GB in the free slot).

I have 3 Dell U2414H monitors that support DisplayPort 1.2 daisy chaining.  I purchased the T440s with docking station.  The laptop arrived before the dock.  It has Windows 8.1 Pro x64 running.  I setup the monitors to daisy chain off of the T440s miniDP port.  I got exactly as I should.  3 separate monitors.  I could maximize windows inside a monitor and they'd maximize to their monitor.  I could drag windows between monitors.  Everything is working. When the dock came in (today) I left the monitors daisy chained.  I did change out one cable (that I know is working) so that the DP input would attach to the dock's DP output.  I am not getting a picture on the monitors.  If I use just one monitor, and turn off DP1.2 (in the monitor's menu), I get a picture on one monitor.  Do these docks not support daisy chaining?  I've verified that I'm on FW 2.17 for the dock.  I also want to submit a support ticket with Lenovo, I just don't know how to do that yet.  Thanks!

This is probably a simple problem, but I can't figure it out. Device: T440s running Windows 10 Pro Problem(s): If I unplug it from the power adapter, re-plugging it has the following effects--it does not recognize that it is plugged in, and the red light over the 'i' on the lid repeatedly flashes a fast sequence of four short flashes followed by a brief pause. It does this until the battery drains and then it shuts down. Adding some further confusion: It will not shut down or restart when plugged in. It will sit on the blue, "Shutting Down" or "Restarting Windows" page for as long as I leave it. I have to force it to shut down by holding down the power button until it turns off. And yet further confusion: If, while it is turned off, I disconnect the external battery and plug in the adapter, I get the standard three flashes to indicate that it's charging. I can then reconnect the external battery, and it charges like normal though the light gives me an occasional double-flash as it charges and the charger gets hotter than normal.So, I'm not sure if this is a bad adapter, battery, motherboard, or something else entirely. I'd like to fix it before my Macbook wielding colleagues catch on and give me grief. Any help is much appreciated.

I have an issue with my new T440s, Win8.1 Pro fully up to date with the latest Synaptics 18.0.7.40 driver from the Lenovo update. I am using a freshly installed copy of Windows rather than the provided image. Sometimes when working with the touchpad and clicking the pad down to drag something, it's as if ClickLock has been turned on from the mouse control panel settings, where it acts like the mouse button is held down until you click (not tap) it to release it again. ClickLock is turned off in the control panel. I found that the issue is greatly reduced (but not gone) if I turn momentum all the way down under Advanced -> Motion. This is driving me nuts as it's seemingly random. If I click and drag to select text then go to move the cursor, sometimes it acts like the mouse button is still held down and I change my selection. Or, sometimes I just want to move my cursor and it ends up dragging something or selecting text. Anybody else experiencing this? Lenovo please can you sort this out. I find myself using the touchscreen more and more as it's simply more reliable than the trackpad!

A:T440s Trackpad - ClickLock bug

Still experiencing this, but not heard anyone else mention it?About 25% of the time when I drag to select text by pressing down the pad, it still acts as if the button is held down after I let go and I have to click it down again. The fact it is so unpredictable is so frustrating, I end up having to double tap the pad to start a drag motion instead.

First off, I am an Electronics Technician by trade.  I have 25 years of experience with all kinds of electronics.  This one has me scratching my head.  This all  started because I had an issue with my touchpad so I changed it out.  During the process I removed all power including, power cord, external battery and internal battery.  Replaced the mouse pad and put everything back together.  When I went to power it up I got no response.  Here are the things I have tried. 1. Hold the power button for a minute.  Tap it 10 times then hold anothe minute.2. Remove all batteries and press the power button for 1 minute.3. Remove all batteries and the RAM module and press the power button.4. Press the reset button through the cover on the back of the machine.   5. Lastly I disconnected the CMOS batter along with all other power.  The last step actually let me me boot up my machine and everything was working like normal.  I was happy I had fixed the problem, but I didn't.  Once I shut down the machine it still will not power back up.  I have to disconnect the CMOS battery again in order for me to powe up the machine.  Once the machine comes back I updated the BIOS to the latest version and that didn't help either.  I am stumped!  Any advice that anyone can give me is greatly appreciated.

Then it stops again )- uninstalling driver and let Lenovo System Update do its job (no effect)- refreshing Windows (no effect)- completely formatting harddrive and reinstalling Windows from DVD (no effect) then trying all of the above again (same effects) I know its not a hardware failure, because when booting Ubuntu the touchpad works just fine! Settings->Touchpad->Additional Settings->ThinkPad shows the Touchpad in Grey.

Hi everyone, I'm trying to figure out if I have a unique problem, or whether this is a broader T440s problem. Occasionally, especially when my T440s has gone to hibernation from sleep, I cannot turn on the computer unless I plug it into the wall. That is to say, when I hit the power button when the computer is unplugged, NOTHING happens. I've tried holding the power button down, pressing it repeatedly, removing the external battery and then pressing the startup button, etc.  If I plug the computer into the wall, it starts up fine and shows that there is sufficient battery life. This does not happen consistently, and is difficult to repeat. For example, the computer went into sleep the night before traveling. I tried to start it on a plane flight (domestic, thank god, so it wasn't a huge issue, but if it had been international that would have been a disaster) and it simply would not start. Later, on a train, I was able to plug it in and it started with no problems and showed plenty of battery life. I then put it into sleep, it went into hibernate, and I was able to start it up without being plugged into the wall when I returned home. Has anyone else encountered something similar? Are there settings I can change, or should I have it sent in for repair (also, what on earth might cause this problem? Faulty power button?)

This is what happened to my T420.  Just about drove me nuts.  Since it would start in one power mode but not the other that proved that it couldn't be the button, right?  Another mod with more sense suggested replacing the keyboard anyway.
 
It was the power button.  On careful visual inspection I could see that it was slightly depressed from normal.  Either partly shorted or high resistance.  Plugging in the AC mains must have changed the voltages just enough for it to work.  Sometimes, anyway.
 
Not saying this weird problem is what you're seeing - but it might be.
 
Good luck,
Z.

No matter what connection I am trying (DP on notebook or DVI, DP, VGA in ultradock) I am getting no communication over DDC\CI message in SpectraView and NaViSet software. It looks like a problem with Intel HD driver. I?ve tried latest stable Intel driver (15.33.22.3621) and drivers from Lenovo (10.18.10.3496) under Windows 8.1 pro (64bits) without a success.Any ideas how to solve that?

A:T440s – no DDC\CI communication with monitor

Did you ever get DDC/CI working? I have a similar problem with my T470p and an UltraDock, no DDC/CI to NEC monitor, no SpectraView calibration, but the built in MiniDP port on the notebook works fine.

I have a T440S that is still under warantty. The screen has a bright white spot about the size of a small led. It can be easly seen on a white bachground from several feet away. On a colored screen it appears as a spot of lighten color. It can not  be seen on a black background. I do not believe that this is a dead pixel. Is this covered by the Lenovo warantty? If not, how easy is it to replace the screen. Are screen whitelisted in the Bios? Can I upgrade this to a touch screen? The current screen is a AU OPTRONICS B140HAN01.2 Can I use any version of B140HAN01 or does it have to be the .2 version? I assume that the 2 refers to the version number.

Hi, I'd like to upgrade the BIOS on my T440s from the original version [GJET83WW (2.33 )] to the latest available here as a CD ISO [GJET92WW (2.42)].How can I do this without using a CD drive? As an aside, I'm running Linux, not Windows, but that shouldn't matter for the BIOS update... Cheers.

On my T440s, the function key's tiny circular green light doesn't turn on when I press it. Is there a setting that I need to change in order to make it turn on when the key is pressed? Or is there something wrong with my laptop. Thanks.

A:Lenovo T440s "fn" key light.

You didn't read your user guide, did you?  See the section on function keys, and the ESC-Fn combo that toggles the indicator on and off.
