Yoga 720-13IKB blinking screen

Q: Yoga 720-13IKB blinking screen

I'm experiencing a very annoying blinking/flickering of the built-in 4K display.Have a look at this short video: https://www.youtube.com/watch?v=Vdd4UICu_T4On the movie it isn't nearly as bad as in reality. The flickering is only visible with a blue, dark gray or purple color background. White, red or black is fine. The issue appears to be independent of the OS - the same can be observed in Linux or even in the BIOS.It all started after I attached a second screen (FullHD 24 inch using Thunderbold->HDMI adapter) in Windows 10 (latest Intel display drivers as of January 26, 2018).Just after connecting the external display the laptop screen went gibberish but the external display worked fine. After disconnecting the screen and restarting the computer the blinking started. It looks like a problem with the refresh rate. The laptop display behaves like an old CRT display with a low refresh rate I found this procedure https://support.lenovo.com/pl/en/solutions/ht500364 in another thread and followed it but unfortunately it didn't help. The computer is almost brand new (bought in December, top version i7-8550U, 16GB RAM, 1TB NVMe, 4K UHD display). Any help appreciated.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

My Yoga 910 turns off the external screen - not when I do anything at all - but when sitting in front of it with external screen. When I leave the desk - then it turns itself off - or rather turns the external screen off. It is sooo weird - I do not TOUCH ANYTHING - just by myself standing up and walk away. It does not happen every time - more like in periods - some days it days - everytime I go away. Other days it just behave normally. This happens when i use my Yoga as a desktop with external screen, external mouse and external keyboard and only using external screen. Bob Johnston

It also does not seem to function properly for most of the time. Even an excel document seems to force it terribly. Sould I consider sending it to service?  Thanks,Gabriel

Purchased new from Best buy in May 2017.  All has worked perfectly until now.  Left my computer for a while while it did some Win10 updates and come back and the Lenovo splash screen is on the screen.  Will not go past that.  I can shut it down by holding the power button but when restated the keyboard lights up and the splash screen comes up and that is it. I have tried pushing the little recovery button while the laptop was off and it does the same thing as the power button and sticks at the splash screen.  $1800 door stop!!! Anyone got any suggestions

Hello,I have many issues with my Yoga 920 that I purchased less than a month ago (but over 14 days). The machine runs Windows Home Intel(R) Quad(TM) i7 8550U  16GB RAM 526SSDFirst as stated above the screen flickers. However, this is only when I travel to my parents' house and connect to their wifi and sometimes at my school in certain locations.Another issue is when typing my cursor often jumps in the text box so I have to erase and reposition my cursor. This is extremely annoying!Next my event log has a TON of error codes; however, I am not a developer so I have no idea if these errors/warnings are important. When I run Lenovo Companion, Webroot or previously McAfee nothing is reported. Is there anyway someone from lenovo can connect to my laptop remotley to figure out what is going on?

I bought the Yoga 720 13IKB Type 81C3 - Model 81C3005LPG - last week to use it for photo edit and I noticied that the screen have strong yellowish tint.I tried to find a calibrated ICM (or ICC) color profile on the vga_drivers folder but could not find it.Also tried to use the windows 10 color calibration tool with no satisaftory results. I'm really disapointed and before start to tell the world on photo forums that this laptop is not suited to photo edit because of this super strong yellowish tint screen I decided to ask here if any members of the comunity or the Lenovo support team have any ICM color profile file that minimizes it.Note that this model have the BOE06FA panel and not the LG (like some USA models I believe).Thanks in advanceHugo Veríssimo

Hello everyone; Because of this problem, I had a notebook changed with the exact same one, for I'd had this problem since the first time I'd turned on the device, and I never solved the issue on that notebook, though I tried many advised solutions on these forums, youtube etc. However, this notebook have come with the same problem. At first time, it seemed like it occurred less than it did on the previous device, and I thought that maybe those solutions would work this time. But it has become more frequent when I have started to run some other applications. I have tried those solutions again; - I have disabled the battery saving modes on Intel Graphics,- I have disabled the adaptive brightness on power management settings,- I have done the BIOS update,- I have done the driver update (done it before but now I also have the problem of updating the driver since the latest update of Windows 10, I can never install a driver update now)- I have disabled the Windows Error Reporting Service and Problem Reports and Solutions Control Panel Support on System Configuration. Despite all these, the blinking never stopped!!! I have been absolutely mad after all these issues. I don't want to make another change of device. There has to be an absolute solution. Please give me a prompt reply. Thank you in advance. *Edited upon wrong usage of vocabulary, sorry..

Hi Folks, I am happy with my yoga, but the bluetooth signal is very weak... I used an App to verify signals and bluetooth power levels. On my Yoga 720 13ikb I have -87dBM at 3 inches from the base of keyboard (Weeeeeeaaakkkk) On my "OLD" dell laptop I have -49dBM at the same distance. (Good/Strong) Why I am asking this? Because I can't connect any of my 3 bluetooth earbuds with my Yoga unless If I am one inch from the hinge (no kidding) Even my bluetooth mouse is jittering to use (I've tried 2). So my questions are: * Does anybody else had the same issue?* I was wondering to open the back cover and check if the antenna cable is connected (since it'll take 7 business days, if lucky to check this issue under warranty) I used the app Bluetooth Signal Strengh Meter 1.8 from Neofrontier Technologies. My laptop is a month old, so far I just have the crappy video bleading (like surface pro 4) but it's okay. Thank you...

I bought my wife a Lenovo Yoga 720-13IKB about a year ago and it has always had trouble connecting to the internet. We are now living overseas (in the Khalij) and her computer barely ever detects the WiFi network at all! This happened occasionally in the US but we could connect it via Ethernet so it wasn't really a problem. But it's pretty much unusable here because of the crap WiFi card, frequency, or whatever in the machine. I've seen some posts asking for help with SLOW internet but her computer almost NEVER gets signal or, if it does see the network, it cannot connect.

Hi All, I've got a Yoga 910-13IKB with a 4k and have also bought a 27 inch 2560 x 1440 pixels monitor to use as my second screen, I'm using an usb-c addapter to connect it. My question is about playing a low requirements game like hearthstone on the laptop screen while having a browser with a few tabs on the extenson, is it supposed to move so slow? Is it because it is heating up? *temperature reaches between 70-80 C. Performance wise it dose not look to be overloaded, but now even typing on the second screen is laggy. I don't mind the sound of the fan, but the temperature and the slow performance is concerning. Thank you! Kind regards,Robert

Hi guys. I recently bought new laptop (yoga 910) and don't properly understand its RAM specs. All oficial docs said that laptop have 16 Gb ddr4 2133 MHz, but tests (Speccy and CPU-z) shows that RAM have only 664MHz for one channel (16.0GB Dual-Channel Unknown @ 664MHz (10-10-10-28)). I heard that using XMP settings in BIOS I can change memory speed, but I can't find it. So, the questions are: does Lenovo downgraded RAM in all laptops and other users have the same specs, if yes, then how to change it (1200 MHz is less then DDR3 speed), else, what should I do next, is it something wrong with my laptop?

Hi.
 
I'm trying to install Windows 10 from an USB flash drive on a Yoga 910-13IKB. I plan to do a clean install from scratch.
 
When I boot the USB flash drive the procedure to install Windows 10 goes normally until I have to select the HDD. It does not find any HDD drive. I guess I need to load some special driver for the solid HDD to be recognized.
 
Is there an special driver or trick to be able to see the HDD ?

A:Yoga 910-13IKB: No HDD on Windows 10 install

Hi Martin,
 
That SSD runs in RAID mode so you need the iRST driver.
 
Download the f6flpy-x64.zip file linked on the left of the below page.  Extract it to a folder on your Win 10 install flash drive.  When you get to the "missing drive" part of the install process select Add Driver and browse to that folder.  That should get you going.

Hello, experienced touchpad/touchscreen glitch repeatedly today on this Lenovo Yoga 910 laptop on Windows 10. After a minute or two from bootup, a greyed out circle or square would appear on the left side of the screen, and the mouse cursor would freeze and disappear. The touchscreen didn't register any input at all. However, sometimes it acted as it was registering many clicks repeatedly. The keyboard worked fine. It seems like a similar glitch was reported with the Lenovo Helix laptops. I seem to have resolved the frozen mouse by installing all updates through Lenovo Vantage. However, the touchscreen remains dead. I removed the HID-compliant driver in order to reinstall it, but now I can't find the driver online to redownload. Does anyone have a link? Or ideas about the touchscreen?

So my Lenovo Yoga would start to boot and the light on the side and keyboard would light up, but then it would turn off again. Then it would start to boot up (without the screen actually turning on) and turn off again. It would just cycle through this, so I held down the power button for 10 seconds, and now it does not turn on at all- no lights, no anything. Any suggestions?

Will appreciate help - I am alarmed that most of my document files have suddenly disappeared from the desktop and, seemingly, the hard disk.  This laptop is eight months old and I initially suspected a "cloak of invisibility" problem while awaiting a software update.  Random individual files and folders appeared in the recycle bin, but most have disappeared completely.  Virus scan and hardware scan have not identified any problems or out of date software.  I did receive a completely blank email today before this happened (no visible sender, no subject line) - not opened - which is suspicious.  Researching this online, I see several related queries about icons disappearing from the desktop, but am doubtful that my issue is the same.   Still unsure if this is a Lenovo update issue or a virus disaster.   Any suggestions?    Many thanks!

Hello everyone,  I recently purchased a Lenovo Yoga 720 13IKB. I've only have the unit for about three (3) weeks and the batter is no longer able to charge when connected to the power supply that came with the unit. I checked the AC adapter to make sure that it was properly connected to PC and it was. I plugged it to different outlets and it didn't help. I bought a replacement powersupply from my local MicroCenter and still nothing. I checked the Control Panel, open up the Power Options to see if there were any settings in there but nothing to show why it wasn't chraging. Then Opened the Device Manager. Under "Batteries" I saw two items, one for the battery and another listed as "Microsoft ACPI Compliant Control Method Battery". I Opened each item, which will brought up the Properties window. Under the "Driver" tab looked for "Update Driver." I went through the two options and did the same process of updating drivers. I went through the driver update process for all options. Once the drivers are all up to date, I rebooted the laptop and plug it in again. Then i unninstalled "Microsoft ACPI Compliant Control Method Battery" completely and reboot. Still the problem persists.  I even updated all the windows Updates. Then I opened Lenovo's Companion app. I updated all the drivers that need updating and nothing changed. I still have my PC connected to AC power and the battery isn't charging. I opened the lenovo setting app and checked under battery section... Read more

A:Lenovo Yoga 720 13IKB No longer charging

Is it not charging at all, or just stuck at around 60%.    I ask because there i an option in Energy Management to select Maximum Battery Life, or Optimized Battery Health, and if set the latter (which I believe is the default), it will only charge to about 60 percent of capacity in an attempt to prolong the life of the battery.    Setting it to Maximum battery life will allow the batter to charge to 100% and you will get a longer run time, but you may have to replace the battery sooner.     If you leave the laptop usually plugged in, then optimized batter health is the better option. Cheers,
