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.)

I just installed a MYDIGITALSSD Super Boot 2 42mm SATA III 2242 M.2 SSD 256-GB in my T440S. The laptop does not recognize a second drive. I can't find the drive to format and use. Does anyone have an idea why that would be? Did I miss something? Thanks!

A:T440S will not recognize M.2 256-GB SSD

For some reason the title changed, I did not type that in. I updated the title. Also, I removed the SSD from the M.2 slot because all of a sudden I lost my track pad. It would not work at all. I could not even access the BIOS. I removed it and everything went back to normal. No idea what could be going on. Any help would be greatly appreciated.

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.

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.

So I'm having trouble with my wifi card on my t440s.I began by putting the windows 7 x86 hard drive in the laptop from my x220, the wifi didn't work so I uninstalled the old drivers and replaced the drivers with the recommended t440s drivers on this site. The wireless worked, I then installed all the stuff lenovo bridge suggested, the start bar stuff annoyed me so I took it out. 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.

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

A:T440s - LG or AUO Display

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.

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!

A:T440s not responding / restarting

Hi Swazi,
 
Welcome to Lenovo Community!
 
I?m sorry to hear that you are facing the issue with not responding on your ThinkPad T440s.
 

Please check with connecting only power adapter.
Check with removing the battery and connecting only power adapter.
Check with removing both power adapter and battery, press and hold the power button for 30 seconds and after 30 seconds connect only power adapter and try to switch ON the system.

If the issue still persist after performing above troubleshooting, then it might be issue with system hardware so we request you to visit nearby authorized Lenovo service center.
 
Click here to open a link where you can select the country and get the exact contact support number. I?m sure they will be a great help.
 
Hope this helps! 
 
Best regards,

Hi, I'm setting up my new thinkpad t440s and I cannot get my trackpoint to work.  It does not respond and in my mouse properties/thinkpad section, the Touchpad is clearly enabled, but the Trackpoint options are all greyed out.  In the pointing options dropdown, I can only see the option to 'Use TouchPad only.'  I strongly prefer the Trackpoint to the Touchpad and would prefer it if possible. I currently have Synaptics pointing device driver version 18.0.7.109, the most recent version.  I've tried rolling back to previous versions and this issue still persists.  I also have gone into BIOS and disabled and re-enabled the Trackpoint in boot settings. Unfortunately, since this is a work machine, I do NOT have the capability to remove the keyboard or replace parts.  Any ideas at all would be greatly 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.

I am trying to add a 4Gb SODIMM to a Lenovo T440s (model 20AQ0062MS with 4 Gb soldered on the motherboard). The RAM is Lenovo part number 0B47380 and should according to http://www.lenovoquickpick.com/deu/accessory/0B47380/lenovo-4gb-ddr3l-1600-pc3-12800-sodimm-memory be suitable for the T440s. I specifically checked that it is 1,35V DDR3L, and I've also tested the same module in another computer, verifying that the module itself works. This computer (BIOS and all firmware versions newest available per System Update) will not detect the added RAM at all, it just continues to report the built-in 4096 Gb as before, and does not give any POST errors. Hardware diagnostics do not report any failures in any of the components, but tests only the same 4 Gb when doing the memory test. A complete hardware reset (removal of all batteries including clock backup) did not change things at all. What am I doing wrong? This is the first time ever I encounter this problem with a ThinkPad, since I started working with the original ThinkPad 700 and 700C back in the early nineties (I used to work at IBM Helpware and OS/2 Hotline 1992-95) . Thankful for any hints. /MarcusBr, Finland

I have installed all that stuff, but nothing changed. My hardware seems to be compatible with Intel WiDi Pro, as I could install necessary software. Also, my antivirus/firewall is disabled. But I still can't get WiDi working - laptop sees my TV, it starts to connect, my TV shows connection, but then it fails.  Please, help me resolve this issue.

My T440s will not power on unless the power adapter is plugged in.  Once it has powered on, I can unplug the power cable and it will stay on. Needless to say, this is not an optimal situation for a laptop. Please tell me there is a fix, and that it does not require shipping my laptop back to Lenovo again. Thanks

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!
