Yoga 15 freezes under Windows 10

I've got a Yoga 15, 16GB of RAM, 1TB SSD. It shipped to me in June with Windows 10 pre-installed, and after applying all updates, it had problems with freezing randomly several times a day. Hardware diagnostics all checked out OK; all OS and Lenovo-supplied updates were applied, BIOS was updated. I even sent it back to the vendor, they re-imaged the drive and shipped it back to me, and after re-applying all updates again, the problem persisted. Eventually I downgraded to Windows 7, and it ran fine for the last 10 months with no freezing.

 

Once the Windows 10 Creators Update came out, I upgraded to Windows 10 again, and immediately the freezing problems came back. I downloaded new Creators Update installation media from Microsoft, formatted the drive, and did a clean install. Applied all updates from Windows and from Lenovo, and still have problems with the laptop freezing several times per day. Windows update has no updates pending. Lenovo system update has no updates pending. All drivers are current. Lenovo hardware diagnostics completes and shows no problems. No errors are written to the Windows event log when it crashes. It's just a hard freeze that forces me to power off and reboot, probably once every hour or two.

 

While I'm confident that downgrading to Windows 7 again will solve the problem, Windows 10 is supposed to be supported on this hardware. What else can I possibly try?

Re: Yoga 15 freezes under Windows 10

Hi there, Mcvlnv                        -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

From a software point of view what I will try to do is try to update some of the drivers of the machine.

Just in case also check the "Windows Task Manager" and check on the "Start Up" tab to see if there is any strange program running on start-up. Also on the "Task Manager" you can organize the programs that are using processor or memory to see the one that is consuming more. Check out which ones, it may give you some hints.

 

Also check if issue persist in safe mode?

 

Update us how it goes.

 

 

 

 

Regards,

Re: Yoga 15 freezes under Windows 10

I believe I've worked around the issue on my own. As I said, all drivers were updated and all Windows updates were applied. In the Windows device manager, I ended up changing the display adapter from the Intel HD Graphics 5500 driver to the Microsoft Basic Display Adapter. I used it like that for a while, and the problem seemed to go away. Of course, that left me without any of the features of the Intel driver (like being able to dim the screen). So I experimented with different versions of the Intel driver:

What I found was that any of the 20.19.x drivers had problems with the system freezing, while the older 10.18 driver did not. So I've downgraded to the 10.18.15.4279 driver from Intel's web site:

https://downloadcenter.intel.com/download/25274/Graphics-Intel-Graphics-Driver-for-Windows-15-40-

That driver seems stable, while the newer ones are not. I suspect it's some problem with the DirectX 19 support. As long as I don't upgrade the graphics driver, I think I'll be OK. But it would be good to see this issue fixed.

Re: Yoga 15 freezes under Windows 10

Update to this: I've now run a week with no crashes. So it was definitely a display driver issue. Hopefully this thread will be helpful to someone else.
