Thinkpad Yoga - ghosting / after-image / watermark issue

Admin Note: This thread has been reorganized for escalation purpose - using ajpot's info for escalation since he was the first to respond to my request of collecting information.
I've got the ghosting issue on my yoga as well. It was OK for the first few weeks (no noticeable ghosting at all) but now it only takes around a minute of having something on screen for ghosting to appear when switching to something else.
I'm in the process of sending my yoga in for repair as I'm experiencing some other issues, so I've asked them to repair the screen as well. From what I've read, it's likely they won't be able to fix it (in which case I'll be asking for a refund) but I'll see how it goes.
Machine: ThinKPad Yoga
Machine Type Model: 20CD-CT01WW
Date manufactured: 3rd December 2013

As amirvf mentioned this is a common issue and there is an active discussion about it over at http://forum.notebookreview.com/lenovo/731068-lenovo-thinkpad-yoga.html Here is a quick recap:TPY uses a 12.5" LG Philips panel that has really, REALLY bad case of image retention (ghosting)The ghosting is not permanent and is actually specific to the way LCD panels work and present on all panels, but usually it's so minor that it is not noticeable to the naked eye. In case of those LG Philips panels, however, the effect is VERY noticeable.Lenovo has a page explaining the general issue: http://support.lenovo.com/de_DE/detail.page?DocID=HT051485The easiest way to check for this is via http://www.marco.org/rmbp-irtest.html (this is a test that was made for MBPro that had ghosting issues, but it works great for testing TPY too)The same panel is used in Dell XPS 12 and there is a long thread on Dell forums complaining about the issue: http://en.community.dell.com/support-forums/laptop/f/3518/t/19497269.aspxThe problem is inherent to the process/chemistry used in the panels and cannot be solved via software/driver update. (Although some support representatives will direct you to partial solutions that flash different colors and can alleviate the issue but only marginally). To fix this issue panel manufacturer (LG Philips) would have to modify it's tech process and a replacement panel would have to be installed.The bad news are that currently there is no solution (AFAIK). They can swap your panels to your heart's delight, but currently there are not panels available that do not exhibit the issue (You should note, however, that the issue is usually less pronounced on a new panel and is gradually amplified over a course of first several weeks, so if you have on-site support and if you/Lenovo are willing, you could theoretically swap your panels every two weeks or so to approximate a real solution). Also note that the market for 12.5" panels is relatively small and there is no real competition, so there is no strong incentive for LG Philips to fix anything (XPS 12 has been suffering from this for over a year now, even through a model refresh)The good news are that Dell has finally acknowledged the issue and are saying that LG Philips has fixed the panels and new batch is coming around February, plus some people have reported that their newly bought XPS 12 does not exhibit ghosting. So, assuming this is indeed so, new panels should trickle down to TPY owners too sometimes. I'd love to see an official acknowledgement/response from Mark on this...

ThinkPad Yoga Ghosting Probleme - 20CD0001GE

Hey! Habe seit ein paar Tagen das ThinkPad Yoga und muss sagen dass mich das auftretende Ghosting wirklich stört. In diesem Post habe ich gelesen dass es möglich sei über den Lenovo Service Support ein neues Display anzufordern. Der Austausch wird in keinstem Fall ein Problem für mich darstellen. An welche Adresse muss ich mich in Deutschland wenden um ein Display anzufordern? LG Hasel

Seems to be easy.
Just contact your local support. They should have some official support in Kuwait I hope.
They have sent the courier to collect the laptop from home. I had to wait about 4 weeks before the LCD replacement panel came to my country (Poland) but AFAIK it is possible to call RMA, report the problem and then wait till they get the replacement for you. The procedure should not take more than few days then. Mind to backup all your data beforehand because the official service used to reinstall Windows from scratch.

ThinkPad Yoga S1 - Windows 10 unknown device

I did a clean installation of Windows 10 on my ThinkPad Yoga S1. After onstalling all drivers I still get followig device missing in device manager:
Unknown Device:Device Type: other devicesManufacturer: unknownPlace: Synaptics SMBus Driver I already installed Synaptics ThinkPad UltraNav Driver 19.0.12.61 from 7/30/2015, so this does not change anything here. What driver is missing and can Lenovo provide it soon?

Also have an S1 with non-functioning palm rejection. The pen worked earlier, but now it no longer functions. It works in that it can calibrate itself in Wacom Pen settings, but otherwise refuses to register. UPDATE: restoring default settings under Wacom Pen settings has reenabled the pen and palm rejection appears to work again. Note: I installed recent Wacom FEEL drivers, which are the drivers that work with this model, among other tablet PCs with Wacom tech.

Thinkpad Yoga S1 not charging and stuck at 800mhz - even after servicing

After giving up and sending my Thinkpad in for service, it still (after being at the depot for two weeks!) still not fixed.
I have to admit, I am dissapointed with Lenovo's service so far, it is clear the technicians did little to no diagnostics at all to confirm the issue was fixed.
My issue is as follows:
1) The computer will run INDEFINITELY on the power adapter. This is NOT a case of a faulty power adapter (occurs with two different adaptors) or a faulty power port (again, the machine will run until the cows come home on the adapter.
2) The computer is stuck at 800mhz. I can get it 'unstuck' as long as it is unplugged and I toggle the multicore option in BIOS.
3) Once plugged in, the CPU will return and remain at 800mhz, even if it is unplugged, shutdown, rebooted, etc.
4) The battery will not charge. The laptop will run off battery power if the battery has power (came back from the depot at 99%, down to 90% now) but will not charge the battery at all, only maintain the level. This is the case whether the computer is in Windows, or turned off.
This is Windows 8.1 by the way, so there is no option to set a charge level to maintain. That being said, last time (before I sent it in) I drained it to < 50% and it still never charged, even when it hit 0% and the laptop stopped detecting the battery (but still ran off the ac adaptor).
The unit also had some ghosting on the LCD, and it took me a while to convince the techs to swap it out. I think my mistake was I wiped the unit, and so they were too lazy (?!) to actually test it, since once you use the computer for 5 minutes it was very obvious (I offered to send pictures, as I documented the issue but they declined). That issue has thankfully been resolved.
This is the first "post-IBM" Thinkpad I've owned, and I have to say between this and that abysmal clickpad I am not impressed.

I recently had this problem too with my Yoga S1 after a system driver update. I noticed during the updates that I received a message that the BIOS update failed. The message came and went very rapidly and the updates continued and completed with no problems. Usually when a firmware update fails, nothing in the BIOS is really changed. I turned the computer off and thought nothing of it. The next time that I turned it on though I too had this problem. After repeated pressings of the power switch and pressing the reset button it finally booted and seemed like all was good, until I did a reboot, and it started again. After much more pressing buttons it finally did boot again. That's when I remembered the failed BIOS update. I didn't trust the auto update program, so I went to Lenovo's site and dowloaded the latest firmware and attempted to update it manually. When I ran the update program it failed again. What I wound up doing was just keep trying. After repeating the update program four or five times, it finally completed successfully. I have no idea why it kept failing or why after many attempts it finally worked. After the update finally worked the problem seems to have been resolved, at least it hasn't done it again,,,yet. Hopefully this will give some others hope in that it can be resolved without sending it off if you can get it to get it to boot again.

Thinkpad Yoga BIOS Update Problem after installing Windows 10

Hi all, I've been reading tonnes of threads here trying to solve my problems (which seem to keep getting worse) to no avail. I'm reaching out to anyone that can suggest some help before I end up bricking my yoga by accident or running it over on purpose. I'll give you a timeline of the events. The machine in question is a Lenovo Thinkpad Yoga 12.5" 20CD-0032USIntel Core i5 4200U 1.60GHz Processor4GB Ram128GB SSDWindows 8.1 64 Bit preloaded (recently upgraded to Windows 10) So the saga begun just a short two days ago. I had some spare time at home and decided to download and install my free upgrade to Windows 10. I backed up all of my important documents etc to OneDrive as I intended on performing a clean install. Said clean install went flawlessly with Windows 10 installing the first time with no issues or errors. Since I had performed a clean install, all my previous apps, including the stock Lenovo apps, had been deleted. I had anticipated this and only really desired to reinstall the app that automatically adjusts the screen orientation when folding the cover back. So in an effort to find this app and any Windows 10 related updates that may be available I went to support.lenovo.com and used the handy Lenovo Bridge app to automatically detect my hardware and suggest relevant updates. While combing through the suggested software I noticed a BIOS update that noted added support for Windows 10. How great, I thought, that Lenovo would have a BIOS update ready so quickly once 10 became ready for mass consumption. I went ahead and downloaded the exe version (not the bootable CD due to the lack of CD drive on the Yoga) and ran the BIOS update. As I ran the update the laptop was plugged in, and no errors were presented, a success message appeared and indicated a reboot was necessary, after a couple seconds the system rebooted itself. Enter nightmare level 1. As soon as the system rebooted, I fired up IE about to look for more updates and......BSOD stating that there was and issue with a driver, after another reboot BSOD again with a completely different file name stating driver file missing or corrupt. Sorry I didn't write any of the file names or errors down. At this point I'm thinking that something is not jiving here between the BIOS and OS. So I tried running repair, and recovery and each time I would end up with a BSOD of some design. It was at this point I made a USB with the Windows 10 x64 ISO from Microsoft in an attempt to run the repair utilities from the USB. Again to no avail. Enter nightmare level 2 After attempting multiple tries at recovering Windows 10 and getting multiple BSOD's through the process I decided to use my Windows 10 USB to simply reformat my hard drive to eliminate any traces of my now apparently corrupt OS and do a fresh install of Windows 10. This appears to have been a significant error on my part. Now I have no OS (BIOS is still intact so at least I think I have a not-bricked motherboard) and everytime I try to boot Windows 10, or 8.1 for that matter, from a brand new USB stick I get constant BSOD's.Sometimes I get as far as the Preparing installation files 22% but am interrupted by a BSOD error at some point. So I am pleading for some help here. To me it seems like the BIOS update was the issue. I was not smart enough to have checked the BIOS version before updating so that I would know what to roll back to safely. What would you all recommend for a rollback and how do I go about doing one with no OS on the machine. I know I'm asking for a tl;dr here but appreciate any advice offered. I really dont want to get to nightmare level 3, which I guess would be a bricked laptop and a bill for a new motherboard or laptop. The BIOS I currently have is GQET45WW (1.25) -Garrett

Thanks for the reply ColonelONeill, It turns out that Lenovo uses an obscure PERL disk image called "eltorito". As such the directions in the link you provided did not work as most common tools (WinZip, 7zip, and WinRAR) cannot extract the image file from an eltorito iso file. I instead just bucked up for a $50.00 Asus USB CD drive and burned the iso for version 1.25 and 1.24 onto discs. I then disabled the setting in the BIOS that prevents rolling back to a previous version and flashed to 1.24 from the disc. While this appeared to go successfully, as soon as I tried to boot from my Windows 8.1 CD I start receiving BSOD's again during installation. I then used the CD with 1.25 to go back to where I was in case it was simply a bad BIOS update at the time. Most of the BSOD's are driver related (qlfcoei.sys) which I don't understand since there is no OS other than what is on the bootable CD (or USB I've tried both) Is there anyone with a stable install of Win 8.1 x64 or 10 x64 running on a 20CD0032US that can tell me what version of BIOS they are running? My next step is to go back to a version that someone else can verify is working. Thanks again for any help.

Issues with Thinkpad yoga on Windows 7 64-bit

I uninstalled the windows 8.1 that came with my Thinkpad Yoga to installe windows 7 64-bit because there was no support for Power Manager ( a tool that allows you to charge your battery only upto a certain percentage (eg 40%) which helps reduce battery aging when the notebook is mostly operated on AC power).
Doing that required me to fully clean the Hard-disk during the installation process.
I installed almost all of the drivers available on http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-yoga-series-laptops/thinkpad-...
for thinkpad yoga and windows 7 64 bit.
Happily, this provided me the Power manager, and I can use it just as I wanted.
However, all these has brought in additional issues which are listed below:
1. The touch pad right click doesn't work. Only two finger tap works as right click.
2. The touch pad gestures for zoom and scroll doesn't work at all.
3. The screen auto-rotate doesn't work.
4. The touch screen gesture for zoom doesn't work.
I did install the ultra-nav and screen-rotate drivers, but I get error messages regarding synaptics ... not working and also sensor driver not working during the windows startup.
Any help please?
Thank you.

Just when I was happy that major issues have been resolved by constant updating, I am now experiencing this frightening problem. Mostly during startup, and lately in the middle of working, the screen freezes, shows very damaged image (like TV noise), produces the most unpleasant sound through the speakers and nothing works. I need to restart and hope that it will be ok. Sometimes it requires 2 or 3 restarts, going to safe-mode and returning back to get the issue resolved.
This has happened three or 4 times within 24 hrs. I searched in the forum and for another model it was suggested that epresscache might be the cause. I disabled the service, but the problem reappeared even then.
Any help please:
This is what appears on the screen when the computer freezes and produces loud unpleasant noise sound.

Thinkpad Yoga wakes up on its own after going to sleep blaming lid if wifi was enabled

Recently I've noticed that my Thinkpad Yoga (20CD00B1US) keeps waking up on its own.
powercfg lastwake returns
Wake History Count - 1
Wake History [0]
Wake Source Count - 1
Wake Source [0]
Type: Device
Instance Path: ACPI\PNP0C0D\2&daba3ff&2
Friendly Name:
Description: ACPI Lid
Manufacturer: (Standard system devices)
It happens either if lid was kept open and I used power button to put it to sleep or if I just close the lid. As soon as I do that I can see red LED goes on and off slowly so I know it is sleeping. However within 5 minutes or less, I see that red LED on top of "i" constantly lit.
If I do powercfg -devicequery wake_armed , I get
Intel(R) Dual Band Wireless-AC 7260
That is really odd. I have WPA2 (PSK) wireless network, and I'm confident other devices are not that smart to send any WOL packets (or whatever it is called for wireless). Also I have AMT and other stuff disabled in BIOS. Intel Smart Connect has Remote Wake set to OFF, Keep Data Fresh is OFF as well. The problem goes away if I turn flight mode (turn off wifi) before sending PC to sleep.
Does anybody else experience similar behavior and what can I do to prevent waking it up without flipping wifi switch? It is so strange that the lid is at blame while the problem is somehow related to wireless adapter.
P.S. Installed BIOS version is 1.05 (not the latest 1.06). All essential updates are installed.
Solved!

You may wish to check the WNIC's properties in Device Manager to see if Allow this device to wake the computer under Power Management is selected. If so, deselect to see if your issue is resolved.

Thinkpad Yoga, not waking up after sleep

I have an issue with my Thinkpad Yoga (20CD).
Sometimes after I have left my Yoga unattended. I come back and find that it's on (red light on) but screen is black, but nothing happends when moving mouse or pressing keys.
I believe this is happens with regards to sleep mode.
I still have some analysis to do wether it happens when power is connected or not, external monitor is connected or not.
I have installed all the latest drivers from lenovos website.

Hi Henrikh,
Welcome to Lenovo Community Forums!
I’m sorry to hear that your ThinkPad Yoga goes to sleep and doesn’t resume normally.
To disable the system from going automatically to sleep mode, go to control panel -> Power options -> on the left hand side, Change when the computer sleeps -> Change “Put the computer to sleep” to never.
To enable a device to wake up the system from sleep, Go to control panel -> Device manager -> Go to "Mice and other pointing devices" and double click on the mouse which you are using and check "Allow this device to wake the computer". Press OK.
Do the same for keyboard as well.
Do let me know if it helped!
Best regards,
Mithun.

Thinkpad Yoga S2 Largest After-Market HDD

Can anyone point me to the highest capacity 2.5" HDD, 2.5" SSD, and m.2 SSD that would be compatible with the Thinkpad Yoga S2 12?
I know that I need to stick to 7mm on the 2.5" drive, and 42mm on the m.2. I was hoping someone else had already done the research.
Also, is the Maintenance Manual downloadable yet?
Thanks for your help!

if you type ThinkPad Yoga in the search box, and click on ThinkPad Yoga 12 in the result list, you will get an error, it has been going on for a while, probably a bug in Lenovo's database, it happens every once a while. submitting ticket to their web admin usually doesn't help, i have tickets closed saying it is fixed and it wasn't, haven't bother for a while.
Anyhow, the workaround is to use the Machine Type for search instead, you can get to the page, e.g. 20DK or 20DL would get you to

Thinkpad Yoga crashes almost every day

A few weeks ago my 4-year old laptop started crashing a few times every week, so I decided to get a TPY. I received a 20CD000MMH (I5, 8 Gb RAM, 500Gb HDD+16Gb M.2 SSD) with windows 8.1 Pro (64 bit) on the 20. Feb and since then the longest time it has kept running is less than 48h. I've been downloading both recommended and optional (12. Feb BIOS update was optional!) Windows and Lenovo's System Updates every day, sometimes twice a day: after a crash System Update usually wants me to reinstall the LAN driver. I've reinstalled Intel's graphics driver several times over as well. For example yesterday screen brigthness was stuck at max after a BSOD, so at least it seems sometimes System Update is right in it's reccomendations.
Currently I have 5 files in the Windows minidump folder, about as many BSODs did not result in any. I've also done 2 resets after discovering in the morning that the computer is almost too hot to hold and won't shut down. Fortunately those have not recurred since disabling "turn off display" last week and checking every time I go to sleep that the computer really is off.
I haven't found many posts from other people who have this many crashes - I'm starting to feel I'm missing something obvious or have a really, really bad example of a TPY. At least there are no ghosting issues, although the SSD worked for caching for only a single glorious day of sub 20 sec. boots. Now I'm back to 1min+...
Does anyone have any advice, besides returning it? The only thing I think I haven't tried yet is messing with the virtual network adapter (http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/Thinkpad-Yoga-not-waking-up-after-sleep/td-p/1348... as I'm afraid of permanently losing the network connection (which has been working fine) or something and I haven't foud any real instructions.

And an update about my TPY also: my local Lenovo service couldn't find any hardware or software issues and it did not crash when it was there for two and a half days. They barely used it though. They did suspect the problem might have something to do with Lenovo and Microsoft programs being incompatible (both have power managers, for example) while running simultaneously. We decided to test software issues by having them reinstall Windows (on a 128 Gb M.2 SSD, which I had bought a few days before as I was sick and tired of the barely functional SSD caching) and by me avoiding any and all updates besides antivirus definitions. So far I've had one crash in 3 days, although it was not a BSOD. It just freezed up while watching a video and I had to reset it with a pin. So things have gotten better, especially considering I now can start using the computer in less than 30 seconds instead of 3 minutes after a crash. It's still not good though and there seem to be some memory issues: when I wake up the computer or restart Windows the setting keep changing for no reason. So far the desktop background has changed color, scaling goes from 125% (which I prefer) to either 100% or 150% and the mouse pointer size changes. Also I've gotten some memory errors (displayed too briefly to write down) when making changes to the account that require me to log off. I'll keep it for a few days and look for additional problems but it looks like I'm going to have to have the motherboard replaced...

ThinkPad Yoga Synaptics TouchPad Error msg on Windows 7 startup and loss of gesture functions

Microphone and webcam not working on Yoga S1 after windows 10 update

I have to admit I never tried the webcam since I got my Yoga which had win 8.1 originally installed on it, but with the update to windows 10, I'm trying more things out. I did install the camera driver from http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-yoga-series-laptops/thinkpad-yoga?c=1 but no luck.I dont even see any kind of camera in device manager. The camera app just says "something is wrong" amd closes. I tried Skype and it also could not detect a working webcam. After installing windows 10, I did try Cortina and it had me go into microphone setup and it was working. However after subsequent updates, it no longer works. The micropphone levels are ll the way 100%, but when I try to setup the mic, I never see the level meters move when trying the speech test dictation,. Ive installed the Conexant drivers in the the above link, and also uninstalled them and tried to go back to what are the default microsoft drivers, neither seem to wor

Hey 22d05da3,
Hey I see that you're having an issue with the webcam and microphone.
This could be a hardware issue knowing both of these features are in the same module
But first,
Can you go to device manager then go under the section that says imaging devices and tell me if the webcam shows up under there. Also, check and see if there's any type of exclamation mark next to it.
Next, Go to the sound controllers section also and let me know if you can see the microphone underneath that.
Now, these two don't have drivers to install from the website. What you can do is uninstall these drivers from the device manager then restart your Notebook. It should install the drivers after you restart.
Also, if this doesn't work you can do a driver recover from the software. Here is a document to show you how to do that.
http://goo.gl/XjqLp
Go down to the section that says "Reinstall the original webcam program that came with your computer".
If any other issues come up before this like you can't find the drivers in the device manager. Go to the section on that document that says " Webcam is not listed in the device manager ".

[New Thinkpad Yoga 12 2015] enable Hyper-V feature on Windows 8.1 pro

Hello,
i am a french customer, and i am very interested in the New Thinkpad Yoga 12 2015, especially the version available with Windows 8.1 Pro. and processor Intel Core i7-5500U.
As an IT expert in Database technonlogies, i used to create virtual machines with the 'Hyper-V client' feature available in Windows 8.1 Pro.
- I saw that the Intel Core i7-5500U processor is compatible with the Intel VT-x and EPT virtualization technologies.
- i saw that the Bios menu offers to enable/disable 2 virtualization parameters (link : http://download.lenovo.com/pccbbs/mobiles_pdf/yoga_12_ug_en.pdf)
Do you know if the New Thinkpad Yoga 12 allows to enable the 'Hyper-V client' feature under Windows 8.1 Pro ?
It is very important for me to have this information, because a computer without the 'Hyper-V client' is not usefull for me
So before buying this computer, i have to be sure that it will be able to enable the 'Hyper-V client'.
Thanks a lot for tour reply

Good day.
Please recall that this is a peer-2-peer support community. It's quite possible with the newness of the 2015 ThinkPad Yoga 12 (gen2), that no members with appropriate information have seen your post yet.
