Lenovo Y720-15IKB screen glitch SOLUTION

This is not a typical post for this site, however I felt that it may help someone somewhere, so here I am creating it. Please read below if you’re experiencing screen glitches on a Lenovo Y720 or a laptop with i7-7700HQ processor.

So you’ve purchased a brand-new laptop – the Lenovo Legion Y720-15IKB (or a similar grade laptop, sporting an Intel 7700HQ CPU) and you’re pretty happy with it, you’re running Windows 10 with the newest Fall Creators Update and then you decide to call it in for the night and put the computer to sleep. Next morning you wake up, wake up your new computer and SURPRISE!!! You’re greeted with this screen:

Lenovo Y720 screen glitch

Task manager, Alt+F4, trying to sign in, closing the lid and opening it up again don’t seem to do anything. You’re left with that screen that seems to only flicker when you try to do something and that brighter square being your mouse which you can move around and only that. Not a bad deal, but if you’re like me, you would want a bit more out of your brand new machine.

It appears that the only thing that works is completely shutting off the computer by pressing and holding the power button for >5 seconds and then booting it up again. This is a bad workaround for two reasons:

  • Your Hard Disk Drive (HDD) that stores all of your files contains fast moving parts. They take damage when there’s a sudden stop. This actually causes somewhat minor damages but when it happens frequently those damages pile up and reduce the life of your HDD. The end result would be your Hard Disk giving out and you losing all of your stored data.
  • Any unsaved work from apps/programs will be lost (unless the program has an auto-save option, only then you have a slight chance of retrieving your project).

Since my laptop was brand new, I wasn’t just going to settle for a work around that could potentially damage my HDD. So I started digging for a fix. Turns out I wasn’t the only one experiencing this issue, there were a number of other people with the same laptop and even some Acer users reported the same screen problem.

A user by the name Kevin174, posted on Lenovo’s forum about the issue actually managed to find what was causing the problem in the first place.

Turns out that the culprit is Intel’s GPU driver ver. 22.20.16.4749. So user Kevin174 posted a solution that rolling back the Intel drivers to 21.20.16.4627 resolved the issue for him. Now before you close this site and try to rollback the drivers or install the old ones immediately, consider that Windows 10 has cached all of the drivers installed on your computer and will install them back upon reboot. In that case what you would need to do is disable Windows Update and here’s how:

  • Click on the Start button
  • Type “Services” in the search bar and pick the result
  • Find Windows Update
  • Right-click on it and choose “Properties”
  • Select the Disable option

Now in order to remove the current Intel GPU drivers, I suggest downloading, installing and running the 3D Guru Display Driver Uninstaller tool. In order to use the Display Drive Uninstaller, you will need to boot your computer in to Safe Mode.

To boot in to Safe Mode:

  • Click on the Start Menu
  • Press and hold the Shift key and then click on the Power icon and select Restart
  • Wait for the loading screen to be over and then let go of the Shift key
  • Select Troubleshoot > Advanced Options and then Startup Settings. Click on Restart (on the lower right)
  • After Windows restarts, you will be presented with a few options, press the 4 key on your keyboard to “Enable Safe Mode
  • Once you’re all booted up in Safe Mode, run the 3D Guru Display Driver Uninstaller tool and uninstall the Intel GPU drivers (by default it’s set to delete Nvidia or AMD GPU drivers, select the Intel ones from the drop-down menu)
  • Once the uninstall is complete, it would ask you whether you want to restart the computer or continue in your Safe Mode boot. Select Restart and it should automatically boot in to the regular Windows.
  • When you log in, Windows should be running with the backup basic GPU drivers. Navigate to where you’ve downloaded the Intel GPU drivers ver. 21.20.16.4627 and proceed with a regular installation.
  • Reboot your computer and everything should be working fine now.

As of the time of writing this post, it appears that the Intel GPU drivers on Lenovo’s official website are the ones mentioned here with the glitch – ver.22.20.16.4749 DO NOT INSTALL THOSE! For the life of me, I have no idea how they’ve let faulty drivers make it to their official website, I guess that’s probably bad Quality Assurance on their side or something but nevertheless – there they are!

Intel appear to have addressed this issue and have rolled out drivers that fix it – ver. 23.20.16:4849 . You can follow this link to the official Intel page with those drivers CLICK HERE . I’ve personally installed those drivers and so far they’re holding up, my laptop is waking from sleep mode without any issues or glitches.

A thing to note for ver. 23.20.16:4849 is that when I tried installing them over the ver. 21.20.16:4627, a notification window popped up, saying that this driver version isn’t signed by my computer’s manufacturer, so it may cause unexpected issues or lack functionality. I proceeded with uninstalling the previous driver with the process described above and then installed the new ones.

Hope this post helps someone that’s currently tearing their hair out on why their brand-new laptop is having issues.

Cheers!
