    HD 620 Generic Freeze


      Hi all,


      I've been suffering from this generic freeze issue with my Lenovo X270 since last September right out of the box.

      Unfortunately, Lenovo (Japan) support has been very passive about this and doesn't agree on a full replacement.

      The machine has been sent for checkups (four times!), and came back with seemingly irrelevant 1) SSD cable 2) SSD replacement, then on the fourth check they swapped out everything internal.

      Yet the problem still persists.


      I've made a post on Lenovo community hoping for help and I did, but without much solution.

      Provide a detailed description of the issue

      Win 10 freezes randomly. Inputs are accepted but screen does not refresh, to be exact. (e.g., I open a notepad before freeze. Screen freezes. While freezing, I type "Hello world" to the notepad. Screen does not refresh. Once unfrozen, the inputs are all reflected.)

      Issue doesn't seem to be tied to any software as it happened 1) right out of the box 2) Clean OS installation with disk partitions wiped 3) Not too sure but Safe mode. Can't find a thing that triggers the freeze/unfreeze.

      The freeze seems to affect only the LFP as I can move my cursor to EFP while the machine freezes. (EFP refreshes normally)

      Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")

      Always (100%): X

      Often (51-99%): X

      Sporadic (20-50%): X

      Very Sporadic (<20%): X

      How to repro

      Please provide steps to replicate the issue.  These steps are very crucial to finding the root cause and fix.
      A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.

      No specific steps to trigger the issue but I have some videos showing the screen before/while/after freezing

      1. X270 freeze - Google Photos


      I have tried updating to the latest drivers but they seemed to have worse freeze frequency than old ones (e.g.

      v21.20.16.4664 had no freeze in a week, but had 7~10 within 30 minutes yesterday night right when I thought this problem was solved.


      All drivers are updated to its latest version via LVantage (updater) and online update lookup in Device Manager.


      I ran SSD, memtest, and motherboard tests to eliminate hardware issue. Also installed Ubuntu and used it for a while to see if it is a Windows problem; seems like it is limited to Windows.

      Lenovo support team has also done a remote session to check my drivers, various settings, and Event Logs but found nothing unusual.


      There is no known way to reproduce and is giving me a headache.


      Help is much appreciated.

          Hello niconuma,

          I understand that you are currently experiencing issues with the system as it is freezing at random moments.

          Regarding this I suspect it is more related to a hardware issue rather than a software problem, however as a troubleshooting step I would like you to update the current graphics driver, this is a generic driver that properly works with your system, however, remember that we always recommend to install the latest one from the OEM.

          Please download the ".zip" file from the link below:


          Once downloaded, please follow these steps:

          1 - Unzip the file to a designated location or folder. 
          2 - Right-click Windows Start icon and open Device Manager.
          3 - Click Yes when prompted for permission from User Account Control. 
          4 - Expand the Display adapters section. 
          5 - Right-click the Intel® graphics entry and select Update Driver Software. 
          6 - Click "Browse my computer for driver software".
          7 - Click "Let me pick from a list of device drivers on my computer".
          8 - Click "Have Disk". 
          9 - Click "Browse". 
          10 - Access the designated location or folder, and access a folder called "Graphics". 
          11 - Select the file called "igdlh64" or "igdlh". 
          12 - Click Open, then click OK, and finally click Next. Drivers are now being installed. 
          13 - Reboot your computer

          After this is done let us know the outcome please.

            Hello David,


            Thank you for the response.


            I also hope this is a hardware issue, however Lenovo repair center refuses to do anything as they couldn't reproduce the issue in the last three checkups (which lasted over a month in total!)

            I have tried using Ubuntu for a few hours to test whether it is a problem related to the hardware or not, and I'm 70% sure it is software related as it didn't happen in Ubuntu.


            Anyways, I have manually installed the latest drivers from the link.

            Still no fix; a long freeze occurred right after updated. There is also a side effect of background image turning into screen full of 1px grey dots in the previous and latest drivers.

              Hello niconuma,

              Thank you for your response,

              Regarding this, if our driver has not properly functioned I would strongly suggest you to try the latest validated version from the Lenovo website: 


              * Please be aware that the content on that site is not controlled by Intel*. This information is offered for your convenience and should not be viewed as an endorsement by Intel* for the merchants or services offered there. *

              This is because we supply generic versions of graphics drivers for general purposes.

To avoid potential installation incompatibilities, we recommend that you first check with your computer manufacturer and use the driver software provided.

                Hello niconuma,

                I am following up with your case and see that we have not heard back from you.

                Were you able to try the drivers provided by the OEM (Lenovo)? 

                If you need more assistance do not hesitate to reply.

                  Hi David,


                  I'm also using the Lenovo X270 and am running Windows 10.  I'm also facing the exact issues.  After closing the lid and then re-opening some time later, the screen is still blank and couldn't wake up.  But I know the OS is still running as I can still ping it.


                  I'm using the latest version the Lenovo is providing.  I'm also trying out all the older versions.... it seemed that the older versions are occuring lesser as compared to the newer ones.  But it's still happening.


                  Please help!  This is really annoying.
