Preferred Solution: VERY DIM SCREEN ON T440S

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.)

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.

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.

I recently picked up a T440s (20AQCT01WW) for a decent price. I'm looking to swap the LCD on it as the one on it has some minor damage. Now what I'm wondering is if it is possible to replace just the LCD on a touchscreen setup. If not I'm not too concerned about the touch functionality and am all for switching to a non touch screen assembly if required. I'd like to try just switching the LCD first as it'd be cheaper. However I'm having trouble finding a lot of information on this. Anyone know where to start? Thank you!

Hi, A few days ago, my T440s laptop has started giving me weird issues. After it wake it, the screen flickers on and off repeatedly. The computer becomes pretty much useless because it keeps bringing me back to the linux lock screen. At first, I thought it might be my Debian installation, but the screen flickers even during the POST and in the BIOS. The only solution I have found is to let my computer rest for a day without power and then I can use it without any problems until it sleeps again. Can anyone point me in the right direction for troubleshooting? Thanks in advance,Marc

Greetings, As the subject describes, my laptop screen flickers quickly and at irregular intervals.  I notice it once every 3-5 minutes or so but it could be more frequent, perhaps at times when I am not concentrating on the screen or it is too light to notice.  It is quite irritating and noticable though.  The flickering started about 3 weeks ago and doesn't seem to be getting much worse.  I spend time in both Fedora 24 linux and Windows 10.  It occurs in both operating systems, but seems to occur more frequently in Fedora.   I had the original screen replaced by a repair shop last year for an unrelated issue.   The flickering is not like the problem posted here:https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-Screen-Flickering/m-p/3300477#M108... Any advice is appreciated.  I am afraid my laptop is no longer under warranty, so I will be stuck paying to repair this issue.  If so, I would probably disassemble and replace the effected part myself since I have the tools and some experience doing this.   Thanks

The screen on my t440s will turn off and computer will go into sleep mode if I adjust the screen.  The screen also occasionally flickers.  I assume something is wrong with the power delivery to the screen, perhaps a wire going to the screen? The laptop is no longer under warranty, but I have experience replacing internal parts of laptops myself.  What part/parts should I expect to buy or replace to fix this issue?  Thanks in advance.Jeff

I recently purchased a T440s with FHD touchscreen. I'm running Windows 8.1 and observing some screen burn-in / ghosting / image persistance. What I mean by this is the following. Suppose I have a window open (e.g., browser window), and leave it open for some time (e.g., 15 minutes). When I minimize the window, I occassionally still see a faint version of the previously maximized window which persists for a while, and eventually goes away. This leads me to think my display might have issues. Is anyone else observing this? I have Intel HD Graphics 4400, and I'm using driver version 10.18.10.3412. I see that there are newer 4400 drivers available on Intel's website, but I'm hesitant to go that route because I haven't seen any other people with this issue so it makes me think that it's not a driver issue.

I agreed to a Lenovo update yesterday (3/21/2018 for my T440s. I remember it saying something about a Bios update and to make sure the machine was plugged in. After agreeing to everything and starting the update, after a while I looked over and noticed that it had a black screen with nothing happening for several hours. The green power button light is on, but when I press it, it just beeps at me. Even holding it down for 10 seconds or more with nothing but a series of beeps (screen stays black with green power button light on). I tried taking the battery out and letting it run out of power, then put the battery back in, plugged it back in and tried to get it to restart. 

A:T440s Bios Update Fail! Black Screen w/ Green Power button still on. (Windows 10 64bit)

One thing you might try that works on some ThinkPads is to reset the BIOS by unplugging the coin cell battery.     That will involved removing the AC power adapter, the main battery and the bottom cover of the laptop, which is detailed on page 61 of the Hardware Maintenance Manual.    Once the base cover is removed, unplug the coin cell battery (see page 67 of the Hardware Maintenance Manual) for a few minutes to let the power drain, and then plug it back in, re-assemble the laptop and try booting it back up. Be careful when prying up the latches while removing the base cover because they can break easily, but I found that gentle prodding and an old credit card etc. can be useful in working the latches free, but you can also get special tools at most electronic stores (often referred to as "spudgers"), to help pry open the case if desired. Best of luck,

Hello,On my T440S, since BIOS v2.37.1.13 (with little hope that v2.39 would fix it, I installed it to no avail), I can no longer enter hibernation.When I try to do so, the red LED blinks multiple times and then the computer immediately wakes up. The event viewer only shows:The system has returned from a low power state.Wake Source: UnknownThe workaround is to either unplug all usb devices, or disable USB 3.0 support in the BIOS, which sucks for a 1000e + laptop.Otherwise, the computer enters a sleep-hibernate-wake up loop which is draining the battery.When do you plan on releasing an update (BIOS or USB 3.0 driver) to fix this hibernation issue?Thank you.

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

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

From then on no operating system, or drivers I have installed, have been able to find the hardware for the Wifi drivers.The bluetooth is working and I have tried using the bios to make sure the wifi function key isn't broken.I have also tried installing windows 7 x64, which is what im working with now, to try and find the hardware.When I go into network adapters, its literally just not there.

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.

My t440s will hang all the time, like this:https://youtu.be/HROnaWhrRDgThe keyboard and mouse are unresponsive. If sound is enabled it makes this horrendous sound. There is no blue screen. It has to be power cycled. It happens every few weeks or so. Has now done it in Windows 7,8 and 10. Have tried updating all the drivers, and it still happens. Have tried using and not using peripherals, and it still happens.

A:T440S hangs all the time

Could be a bad hard drive or RAM (both of which can be tested using Lenovo Solution Center), but I would start by noting the time of the hang, and then rebooting and checking the Windows Application and System event logs upon restart to see if there are any errors reported that stand out.    I once had an issue similar to what you are seeing, and the logs pointed to a hard drive controller error, which in the end was not the controller, but a bad/loose ribbon cable that seemed to act up when the system got hot. Open Windows Event ViewerStart >> Run and type: eventvwr Press Enter Good Luck,

I have exactly same problem. However, I don't think that this is driver problem since this buzzing is heard even when laptop is in bios. From what I can tell, sound(buzzing) is comming directly from speakers.(both of them) And you are right, it is extremly annoying and it is killing this otherwise very quiet laptop.

Hi Icewater,
 
Welcome to Lenovo Community!
 
As per your query we understood that you are facing issue with switching on the system ThinkPad T440s.
 

Check removing the battery and re-plug it.
Go to BIOS and set the BIOS to default setting.
