T440S PWMTR64V.dll

I keep getting this error message when I boot up my computer:
"There was a problem starting C:\Program Files (x86)\ThinkPad\Utilities\PWMTR64V.dll The specific module could not be found"
I went to this forum and found that I was suppose to uninstall the lenovo power management driver and reinstall an updated one.
I am using Windows8.1 (64bit) so I went onto the lenovo support website:
http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t44...
and downloaded the latest version (n19ku12w.exe) but it didn't fix the problem. I went to check the folder 'C:\Program Files (x86)\ThinkPad\Utilities\' and the PWMTR64V.dll is still missing after reinstalling it.
I am just wondering what's the problem and how can I fix this annoying problem. Thanks.
Solved!

I have the same problem too. I have a T430 and started having this problem today morning.
The guys at Lenovo should fix this. I think it has to some with something about their latest updates.

After boot PWMTR64V.dll not found Windows 8.1

After STARTUP I get the following error message on a brand new E440.....There was a problem starting C:\Program Files (x86) Thinkpad \ Utilities \ PWMTR64V.dll. The specified module could not be found.
How do I get rid of this error message. Took a look at the registry but could not locate key to delete and in windows 8.1 there doesn't seem to be a Lenovo power manager program to install as in windows 7. What are my options here? Thanks?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

There was a problem starting C:\Program Files (x86)\Think Pad\Utilities\PWMTR64V.dll

Getting this error on every reboot: There was a problem starting C:\Program Files (x86)\Think Pad\Utilities\PWMTR64V.dll Cannot uninstall Lenovo Power Power Management Drive All on Windows 10 64bit. Lenovo Twist. Had installed the latest version (1.67.10.15).

There are 2 separate things here:
1. Lenovo Power Management Driver - this is supported on Windows 10 but needs to be updated to a recent version: http://support.lenovo.com/us/en/downloads/migr-4gxpeg
2. Power Manager - this is not supported on Windows 10 and should be uninstalled.
So have you uninstalled "Power Manager"? The PWMTR64V.dll file comes from Power Manager

Missing DLL after Lenovo System Update

I upgraded to Windows 10 on my ThinkPad Twist. After that, I ran Lenovo's System Update and downloaded and installed all the recommended updates. Now when I reboot I get a message saying that C:\Program Files (X86)\Thinkpad\Utilities\PWMTR64V.dll is missing. Searching the Lenovo support site for this DLL file name shows that it is related to Windows 7 Power Management. However, one of the updates from Lenovo was Power Management for Windows 10. I am hesitant to install the Power Management update for Windows 7 (which I'm guessing will solve my missing DLL problem, but maybe not) after installing such an update specific to Windows 10. But I don't want to have to have that popup message about a missing DLL every time I boot. Anyone know how I can resolved this?

Hello,
theo, thank your for providing your solution. Please click solved to your thread.
Yes some updates can cause problem, especially R&R or CSS.
It´s important not to download everything and carefully read the read me´s of every update,
to avoid problems like this.

Lenovo Twist & Windows 10

Well I completed using the ISO and upgrading from 8.1 to Windows 10 on a Twist (with i3) and a T440. The Twist took about 5 hours to upgrade. It hung for about an hour on the first logon. Please note that this laptop is a domain member and is runing the Pro version of the OS. I did get the message that things are taking longer than expected but it did eventually complete. Then I ran Lenovo System update and Windows update. System update only updated the system updater and the Intel Graphics; windows update did all the other drivers. The results is that the Twist is very slow, difficult if not impossible to logon (lots of delays), touch screen is slow and at times just won't respond any more. New Edge browser is slow, it appears that a screen is loaded and as you are reading if you try to scroll or do anything including closing and re-opening nothing will happen until all the ads and video has loaded. In conclusion the edge was a great product and ran 8.1 great. At $360 it was better than and Surface Pro or other laptop/tablet combo. With Windows 10 it has become a brick. Fortunately I did a backup prior to the upgrade so I will now do a full restore and get it working again. I hope this helps others.

There are 2 separate things here:
1. Lenovo Power Management Driver - this is supported on Windows 10 but needs to be updated to a recent version: http://support.lenovo.com/us/en/downloads/migr-4gxpeg

BUG: Power Manager fails to autostart

Alright, this topic is a continuation of my conversation with Lenovo support on Twitter, as it has been a while and we were unable to resolve this problem.
Until recently I had Windows 7 x86 running perfectly normal with a number of ThinkVantage tools such as Power Manager, HDAPS protection, HotKey integration, etc. - all the bare necessities, though not the latest versions.
Recently I've formatted everything and installed Windows 7 SP1 x64. Immediately after installation I've installed the latest versions of Power Manager, etc. from Lenovo Support website (i.e. not through System Update). Upon installation, the Power Manager gave me this error:
Every time I rebooted my computer, the same thing showed up and the Power Gauge was not showing in the taskbar. After a bit of looking around, I have found that in the following registry entry: HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run in the value rundll32 "C:\Program Files (x86)\ThinkPad\UTILIT~1\PWMTR64V.DLL",PwrMgrBkGndMonitor the quotes were missing. Once I put them in, the Power Gauge started to show up during start up, however the message did not disappear.
Then I tried installing the APS protection which gave me a couple of the very same messages during installation. When the installation finished, I tried running the APS protection from the Control Panel, but it crashed every time.
Highly dissatisfied with all this, I've formatted the hard drive again, installed the same version of Windows and installed the Power Manager the very minute it finished installing, to be sure no other applications intervene. The result was the same.
From @lenovo on Twitter I've received an advice to uninstall the Power Manager and try installing it from System Update, however the same error message prevents me from uninstalling the Power Manager. I have also tried using the System Update to install the HDAPS (which I haven't installed this time), but it failed.
So there's my story. Any help would be very appreciated, as never before have I had a single issue with Lenovo tools.
Thanks!
Solved!
Go to Solution.

All right, I've gone through some experiments in the VMWare. Installing my modified image and then the Power Manager gave the same errors I am experiencing. However, when I used the untouched image, everything worked fine.
So I would like to thank everyone who contributed to this topic and apologize to @Lenovo for taking their time with this issue.
Yet I am very interested in what it is with the modified image that makes the Power Manager installation use paths like C:\Program Files (x86)\... instead of C:\Progra~2 like it happens with the normal image, which I just verified comparing registry entries. And also why the ThinkVantage tools are the only ones affected by this.
But in any case, thanks to everyone again and I will accept this solution now.

Compilation of Lenovo X120e issues and solutions

Just thought a compilation of issues may be beneficial for folks who own an X120e.
Screen adjusts brightness automatically without user input depending on content on screen:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X100e-screen-brightness-increasing-by-itself/td...
This is caused by Vari-Bright being enabled in the Catalyst Control Center. With this option enabled, the screen will automatically adjust its brightness depending on what is shown on the screen. The display brightness is increased when the screen is predominantly white while the display brightness is decreased when the screen is predominantly dark. An easiest way to see this effect happening is to have two tabs opened in a web browser window. Set one tab to display a website that is mainly filled with white pixels (such as this Lenovo Forum) and another tab to display a website that is mainly filled with dark pixels (such as http://www.krijtenberg.nl/ ). Switch between the two, pausing a few seconds in each tab.
Solution:
Open the Catalyst Control Center and select the PowerPlay option in the Power section. Uncheck the Vari-Bright option (or adjust the slider) and click Apply. Verify that the automatic adjustment is no longer occuring by doing the two tab experiment described above.
Function keys for brightness control not working after waking from sleep / hibernation in some instances:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Funtion-keys-for-brightness-not-working/t...
For my X120e, whenever I have it sleeping or hibernating and change the power source (such as initiating sleep when on power and then waking it up while on battery, or vice versa), the function keys for brightness controls do not work.
Solution:
Restarting the machine will bring back functionality of the brightness control keys...
A way to prevent this from happening in the first place is to wake the X120e in the same power state that the X120e was put to sleep in (wake up from power adapter if slept while connected to power adapter, or wake up from battery if slept while on battery).
All we can do now is wait for Lenovo to come up with a fix on their side of things.
AMD SATA Controller and TRIM for SSD:
The AMD SATA Controller provided by Lenovo does not support passing of TRIM command according to http://www.hardwarecanucks.com/forum/450343-post35.html for SSDs. The Lenovo provided AMD SATA Controller is 1.2.1.197, before the official TRIM support in 1.2.1.263. If you're using a HDD, this is of no concern.
Solution:
In order to have support for passing of TRIM command, one has to update the AMD SATA Controller to any version above 1.2.1.263 ( http://sites.amd.com/us/game/downloads/Pages/integrated_win7-64.aspx#3 for Windows 7 64-bit, for example) or uninstall the AMD SATA Controller to revert back to Microsoft's Standard AHCI 1.0 Serial ATA Controller.
Disclaimer: Since the AMD SATA Controller driver linked is not from Lenovo themselves, I'm sure they won't provide any support if something is to occur so try at your own risk.
As HP79 mentions below, at least according to the update notes, TRIM implementation is implemented for Hudson chipsets as of 1.2.001.263.
Audio Stutter / Slurring occuring during playback of video/audio:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Stuttering-Audio/td-p/389023
This issue can be reproduced (at least on my X120e) by waking the X120e after putting it to sleep. The symptom is the audio repeating a sound over a span of a second or two during playback and is quite noticable.
Solution:
uEFI Bios version 1.11 seems to deal with the audio stuttering issue. So far, results lead to positive outcomes.
Old Solution:
PWMTR64V.DLL that is loaded at Startup seems to be causing this issue. Disabling it from launching when starting up seems to cure the Audio Stutter (even after waking up from sleep which was seen to be a pretty reliable way to get the issue to repro). Start Menu > Launch MSCONFIG from the Search Bar > Select Startup Tab from the System Configuration window > Uncheck Thinkpad Power Manager > Restart.
This does not seem to turn off the power manager application itself so settings in Power Manager can be saved and it seems to still be in effect. However, opening up Power Manager from the notification / taskbar can cause audio stuttering and mouse movement slowdown while it is launching and/or when applying settings. This is only temporary and is gone when Power Manager is closed. (Thanks kns7977 for the find)
Pending to see if those who uninstalled Power Manager are able to turn off the offending startup .dll.
Mouse seems to stutter or stay in place for a moment when moving:
This seems to be caused by the same issue causing the Audio Stutter / Slurring. At least at this time, the cause of the issue and solution seems to be the same.
Emulating Middle Mouse Button with Trackpoint:
One can set up the middle button between the left and right click button for the TrackPoint to act like pressing a middle mouse button on a standard mouse by changing the scrolling type to Smooth instead of the default Standard.
Control Panel > Hardware & Sound > Mouse > UltraNav Tab > Setting for TrackPoint > Setting for Choose Scrolling or Magnifying Glass Function > Smooth.
Trackpad's two finger gesture being hit or miss:
The trackpad's two finger scrolling is very hit and miss.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-Touchpad-issues/td-p/393751
Solution: Turning off Gesture Filtering may alleviate the problem. As mentioned in http://forum.notebookreview.com/lenovo-ibm/561751-x120e-owners-thread-24.html#post7323293, it seems that the Gesture Filtering is counteracting any sort of two finger input.
Get to Mouse Properties by Fn + F8, select Manage Settings. At Mouse Properties, select the UltraNav tab > Settings for TouchPad. Expand the Smart Check Settings, highlight Gesture Filtering, and uncheck the Enable Gesture Filtering box and Apply.
Screen flickers lines:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Flickering/td-p/389523
Had this issue occur on me once, but never seen it happen again. Unsure what caused or cured it.
Solution:
If the flickering is occuring, a restart is all that is needed to alleviate the problem. Haven't tested if hibernation fixes it, but neither sleep nor turning off the screen with the Power Manager dealt with the flickering.
3-Cell Battery mentioned as a 40Wh in the Order Page of Lenovo X120e when it is actually rated as 32Wh according to Power Manager:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-3-cell-40Wh-battery-reported-as-32Wh-by-P...
Yeah...
Solution:
Accept that it's a 32Wh you will get when selecting 3-Cell or go for the 6-Cell if you want more than 32Wh.
2x2 ABGN Driver from Lenovo triggering Error Code 10:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-ABGN-Driver-issue-in-Windows-7-Pro-x64/td...
The Wireless driver from Lenovo's site seems to not work with the 2x2 ABGN wireless when installed on a fresh copy of Windows 7 x64.
Solution:
Not really quite a solution, but one can bypass this by either installing the 32-bit Windows 7 and installing the 32-bit driver, or using the factory recovery disc to install 64 bit windows 7 to have it install drivers that work for x64 windows 7.
X120e bluescreens after installing LAN Realtek 7.26.902.2010 drivers from Lenovo's Driver download site.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-bluescreen-when-installing-lan-drivers/td...
The drivers doesn't seem to work and it causes a bluescreen on fresh installed Windows 7 x64.
Solution:
As Clicq suggests, Realtek's own drivers from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTy... seems to deal with the issue.
Screen quality on the X120e:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-poor-LCD-quality-viewing-angles/td-p/3945...
The quality of the screen on an X120e is below expectations.
This is common with low-quality TN panels not helped by glossy displays. My personal X120e screen likes to bleed certain colors of red.
Solution (not really):
One can use the Windows 7 built-in color calibration tool to adjust the colors to make it more tolerable. Adjusting your own viewing angle in relation to the screen might deal with some color issues (hard to figure out what's the correct viewing angle because of TN panel's small range of optimal viewing angles). Also, changing the refresh rate to 60Hz may deal with some headaches due to the screen (as it did for me).
HDMI Overscan to HDTV issue:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/HDMI-overscan-to-HDTV-issue-on-x120e/m-p/395335
There is a black border when outputting to HDTV through HDMI.
Solution:
AMD's CCC by default sets a specific value for overscan / underscan. One can http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Output-to-TV-via-HDMI-port-black-border-on-the-... while the device is connected via HDMI (the option is hidden if the HDMI port is not used) and adjust the slider to an acceptable value.
Skype asserts after 10-20 seconds of video chat:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Skype-quits-after-10-20-seconds-of-video/...
When doing a video chat, the video feed will freeze and then skype will crash to desktop.
Solution:
Version 5.3 of Skype seems to be the culprit. Until Skype itself is fixed, one can use Skype 5.2.60.113 from http://www.filehippo.com/download_skype/changelog/9465/ to bypass this issue. Just reject any offer to update to 5.3 after installing 5.2, for now.
If there is anything I missed, please respond and I'll update this post with new information. These are the ones that I have encountered so far with my Lenovo X120e. Don't get me wrong, I like my X120e... it's just been a "learning" experience lol

Urgent Issue with X230 Windows 8.1

I have upgraded my ThinkPad X230 to Windows 8.1.
I get the following two message every time I start
1. Power Manager Group: An error occurred while loading a resource DLL.
2. Problem starting C:\Program Files (X86)\Thinkpad Utilities\PVMTR64V.DLL. A Dynamic Link Library (DLL) utiliization routine failed.
I uninstalled Power Manager 3.06 but I still get the errors.
Please tell me how to either (a) get rid of the errors or (b) point me to a newer link to Desktop Power Manager to install.
This is quite urgent (error every single startup).
Thank you.
Solved!
Go to Solution.

Uninstall Power Manager
Go to C:\Program Files (x86)\ThinkPad\Utilities and rename PWMTR32V.DLL and PWMTR64V.DLL as _old files.
Get Glary Utilities or counterpart and remove PVMTR64V as a Startup Item.
Problem Gone.
However, Windows 8.1 delete Windows 8 Power Manager and there appears to be no way to get it back.

T450 - Power Manager crashes after Sysprep

After Sysprepping a T450 with a clean Windows 7 64 bit Professional custom build, Lenovo Power Manager crashes with "An error occurred while loading resource DLL". Followed by "There was a problem starting C:\Program Files (x86)\ThinkPad\Utilities\PWMTR64V.DLL The Power Manager toolbar on the taskbar also will not load. Reinstalling Power Manager (latest version 6.67.5) resolves issue. Reinstalling it immediately prior to Sysprep does NOT resolve the issue. Anyone else seen this?

Probably because the tools aren't added to the taskbar in "Default" user. Did you added the tools to the taskbar in Audit mode?
Though sysprep will not keep some settings. You may need to use `unattended.xml` to configure scripts to add those tools to the taskbar.
Just another question: does the PM tool appears in its factory state?

Thinkpad Edge vs. Power Manager

I'm not sure if this is widespread, but it certainly drives me crazy as a new owner.
While the system was fine and good, once installing Power manager, it always leaves rundll32.exe running in task manager.
The feature works fine though ( at least seems so ), you'll only have to manually kill the process each time after boot.
This is unchanged on v3.66 and v3.67 of Power manager ( having the latest BIOS )and running Win7 64bit.
So far the only remedy was to completely uninstall Power Manager.
I hope someday this will be fixed.
If someone would know the fix, I'd appreciate hearing about it.

How do you know Power Manager is causing this behavior?
Is it this entry in msconfig startup tab (see below)?
If you disable this entry, does the behavior you described stop?
rundll32 C:\PROGRA~2\ThinkPad\UTILIT~1\PWMTR64V.DLL,PwrMgrBkGndMonitor

T410 Power Manager

The Power Manager seems to have a mind of its own and is bcoming quite annoying:
The screen brightness always defaults to full bright when starting, or coming back fro sleep, screen saver, etc.
The fan changes pitch randomly
The Power Manager seems like a good idea, but having to reset the screen brightness over and over is too much.
Can this be corrected? If so, how do I do it?

I also hit the power gague not displayed problem on win7 64bit edition. The windows registery key for C:\PROGRA~2\ThinkPad\UTILIT~1\PWMTR64V.DLL is not incorrectly under wow64 registery entry. This cause the power manager background service not started when Windows is started.
To fix the problem, Just add a run entry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\ with value "rundll32 C:\PROGRA~2\ThinkPad\UTILIT~1\PWMTR64V.DLL,PwrMgrBkGndMonitor".

Lenovo Settings Dependency Package for Windows 8.1 - fails on T440s

Hello everybody,
I just tried to install the Lenovo Settings Dependency Package for Windows 8.1 on my T440s and it repeatedly tells me that it fails because mfplatt.dll is missing. Has anybody experienced that and knows how to proceed in this case?
Thanks for your help

I confirm the problem on T510 too.
I have Windows 8.1 PRO N.
I installed the windows Windows6.3-KB2835517-x64.msu windows media package.
After this, I can restart Lenovo Settings Dependency Package and it works wright, without the error on MFPlat.dll
And after it works, my camera started to work correctly!

T440s new wifi 17.12 driver fails after coming out of hibernate

Coming out of hibernate no wireless networks are available. A reboot resolves the issue.
Plugged in or on battery - same issue.. Bluetooth enabled or not - same issue. Tested twice to make sure I wasn't crazy. I hibernated and came out at least 8 times a day on old driver. Same with sleep.
Downloaded this driver here for AC7260 which connects to an Asus RT-AC66U. This new driver (mine is for 8.1) is for a lot of machines and a lot of wifi cards.
http://support.lenovo.com/ca/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t44... Installed everything except the enterprise tools because I know how they conflict with connecting to wifi, and I would prefer to connect to wifi through Windows. I tested with the tools as well.

Happy hunting

Skoop:
Interesting. Fortunately for my T440s, this was resolved a couple releases ago. Or maybe the last one. This particular update broke it therefore in the long run, Lenovo will have to take a look at this, at least for some of us. To note the bluetooth driver was not updated with this package. Only the Wireless.
I myself have had no issues with the 7260 on a couple different machines, including an HP and this Lenovo. Although, I am on Windows 8.1 with the latest updates and you are on Windows 7. Perhaps prolonging the jump to 8 may be bad to your health. haha. Why are you on Windows 7? Don't like Windows 8? I remember when Windows 98 came, I refused to go to it. The same with XP lol (I skipped the umentionable) I had a really hard time letting go of that one. skipping another unmentionable) For awhile I didn't let go of 7, however by Windows 8.1 update 1 (or whatever they call it) I was sold. Things are handled more efficiently. Perhaps Windows 7 only came with your machine, however if you have Windows 8 recovery discs for your machine, I suggest you use them or buy a license (especially if the trackpad matches the T440s hahahaha trust me like night and day, but still bad) Windows 8 will soon be an unmentionable because of the charms bar, lack of start menu etc with the upcoming release of 9 beta. (screenshots recently or possibly leaked) At least getting to 8 may solve some problems until 9 comes.
I attempted a manual install of the wireless drivers alone myself to skip the software install.. This was a trick we used to use in support back in the Windows 95 days. ESPECIALLY for modem drivers. hahaha Then we had to change IRQ's and so on, search for phantom drivers blah blah Anyway I am reliving the old days. There was a Win8 and Win8b directory for this particular driver package. Neither worked for manual install. Which is VERY odd. I checked out most directories and could not find anything applicable...but i didn't put too much time into it so perhaps it is there lurking in one of the folders. I had a close look at the .inf's within 8 and 8b as well, but only long enough to no waste the day.
Looks like you being on different hardware (perhaps) and on Windows 7, you have been experiencing this problem for much longer than us T440s folks on Win 8.1. I myself resolved the issue a long time ago by not allowing it to turn off or "save power". At least i think that is what I did. Make the jump to 8 and simply install that classic start menu software. It at least gives you a normal start menu and more and then you can disable any other Windows 8 stuff you don't like.
By the way, as far back as I can remember Lenovo's (previously IBM) extra wireless mgmt software has been breaking machines. Like forever. I really cannot believe that this has not been done away with yet. Like, I REALLY can't believe it. I saw that yellow bulb and my eyes popped out of my head and I threw out a big chuckle. I mean at least they could have fixed the fact that perhaps after install, it prompts you as to whether or not you would like to use the "Windows tool, or the Lenovo tool" haha nope. Such an easy thing to code. However as I type this, I realize exactly the types of machines we have here....they are the same as they were a decade ago. These machines should be marketed to tech geeks who like to tinker and fix things. No offense to Lenovo...however a lot of software, bios updates the machines themselves, (buggy down to lights not staying on on the keyboard as you boot up) and even their support website....(I mean seriously when you return to the main driver page you really have to sort by date, again? Like again? hahaha The layout is terrible,,and pricing errors. How can I explain this. I know - ueverything is unnecessarily complex. Even the bios looks yesteryear. (other than Uefi portions I'm sure although I have not trod there) I always come back though, probably because I like to tinker
I'm rambling. Bottom line I may be wrong however maybe a jump to Windows 8 may help some others on other platforms. Who knows. In the meantime, it seems at least two of us on two different hardware platforms had things busted up by this release.
Cheers

System update makes Windows 7 on both T440s and E531 not starting up

I install windows 7 on both a Lenovo E531 and a Lenovo T440s and afterwards install system update. The first time system update ask me to restart, Windows wont start up again, It reach the Windows logo and then turn black where only the mouse shows. Does system update have problems or is it one of the drivers already installed which colide with system update?

Your problem is with MSVCR100.dll. Google this as there are several hits on how to correct problem. Here is one. http://forums.adobe.com/message/5402850

T440s doesn't wake up from sleep

I got a new T440s about 2 weeks ago and sometimes it doesn't wake up after it goes into sleep mode. It gets stuck on a black screen and the mouse cursor is visible, but moving the mouse or pressing keys on the keyboard fails to wake it up. When this happens, I have to restart the computer by holding down the power button for 10 seconds. I am running Windows 7 Professional 64 bit and hybrid sleep is off. I'm just really confused because sometimes it wakes up perfectly and sometimes it doesn't. Thanks!
Solved!

Hi someotherguy, firstly thanks for your replies!
I'll try to document my issue a bit better.
My setup:
Thinkpad T440p
CPU: i7-4700MQ
OS: Windows 8.1 Pro 64 (Upgraded via STORE from Windows 8)
Display: FHD WWAN
Graphics: Intel HD4600 / GeForce GT 730M
Memory: 16 GB GSkill 1.35v
HDD: Samsung 840 Evo SSD (250 GB)
Power: 135W AC Adapter
Wireless: 7260AC w/ Bluetooth 4.0
External display: LG 23EA63V-P (LG 23 Inch IPS Panel @ 1920x1080)
Connection: MiniDisplay Port to DVI Adapter with Dual link DVI-D Cable
Power settings: Max Performance / Always On
Sleep: Never
Turn off Displays: YES (this is the issue!)
I have disabled hibernate
I have disabled fast boot
I have installed all latest Windows updates and Lenovo drivers.
Nothing to call out in device manager
The issue:
Since adding the external display, both displays intermittently (90%) fail to wake from DISPLAY ONLY sleep. The system does (*knock on wood*) wake from manual setting of Sleep. However, when the displays turn off after the allocated time, it seems like my system is in tandem assuming some sort of sleep state. It does not look like only the displays are sleeping.
Once the monitors turn off, moving the mouse or hitting the keyboard will initiate some system feedback (backlight only on laptop lights up with blank screen, fans spin up) but the external monitor does not power back on, and the keyboard lock keys do not respond. The only way to get my system back is to hard reset.
Now I have read several users having similar issues. Many users have solved this in different ways (from display to usb to power to memory), and it's very hard to identify the culprit in my situation.
Other issues (possibly related)
-Sometimes system turns off by itself (rarely occurs)
-Sometimes after desktop is idle for 1 minute, system Logs Off (and in turn displays turn off)
What I've tried that has NOT worked (aside from latest drivers)
-Disabling Hibernate
-Removing all USB devices
-Disabling Wireless adapters
-Disabling Bluetooth
-Uninstalling Bluetooth (yes I've updated to latest drivers)
-Disabling Fingerprint Reader (yes I've tried the latest drivers)
-Updating to latest BIOS (although I updated last night and I think it was to 2.18 that was just released?)
-Installing Intel HD Drivers versions: 3345/3355/3379
-Installing latest Nvidia Optimus drivers
What I've tried that SEEMS TO SOLVE IT (at least temporarily)
-Switching Single Link DVI Cable -> Dual Link solved it temporarily, but the issue came back.
-Uninstalling Intel HD4600 Drivers (using an old 3316; but this causes high CPU usage and System interrupts)
-Disabling CPU management in Power settings in the BIOS (this to me is not a solution)
-Switching to MiniDisplay Port to HDMI adapter & HDMI Cable; this was my biggest victory last night - I was able to get the displays back 100% of the time (3 tests)
-Switching BACK to my DVI adapter and cable - this has me puzzled. I would rather use DVI, so ruled out using HDMI as a solution. Once I changed the cables, I was able to resume the system again (in my few tries). We'll see how long this lasts..
So I'm still not sure what the issue is. Things I would try, but only if necessary..
-Shorter Dual Link DVI Cable
-Different MiniDisplay to DVI adapter
-Reset PC and OS (factory settings AND fresh install)
-Windows 8 Pro (do not upgrade to 8.1)
-Different Memory
After checking the Event Log, I've had Critical Events (system powered down unexpectly) each time I've had to hard reset. I try to see if any Event occured just prior. I've noticed several Warnings for the following, but have found no pattern tied to the crash
-igfx.dll has stop responding / has recovered
-issue with Finger print reader (I need to reference Event Log for details)
-issue with Bluetooth (I need to reference Event Log for details, but I believe this was when I had it disabled in the Device Manager and it was looking for the driver)
Sometimes there is no event just prior to the crash at all, which leads me to believe these are just OTHER issues I need to deal with.
Any other experiences/thoughts/advice would be most appreciated! I have been so incredibly frustrated recently, coming back from another room finding my displays off and having to hard reset. Sure there are workarounds, but I am in seach of a solution.
And this is only ONE of the issues I've had with this device.
