The Yoga 2 Pro from Lenovo (Model# 20266) has a known issue with constant flashing that doesn’t stop unless you close the lid or shut down the system. The flashing didn’t start until I upgraded from 8.1 to Windows 10 (Home & Pro).
Well, after intense research for over 2 years, I’ve finally figured it out. Here are the magic steps:
- Run the Intel HD Graphics utility (GfxUIEx.exe) as an Administrator (or it will crash). You can do this by either one of the following:
- From the Windows menu (Press the Windows logo on your keyboard and type “GfxUIEx.exe”. Then right click to Run As Administrator.
- From CMD.exe, run this command (runas /user:Administrator GfxUIEx.exe). Then you will have to enter the admin’s password.
-
After you open the Intel HD Graphics Utility, do the following:
- Click on Display -> Change the Refresh Rate to 48p Hz -> Click APPLY
- Click on Power -> On Battery -> disable the “Panel Self-Refresh” option -> Click APPLY
Updating the BIOS, and all other drivers updates didn’t really make a difference. All you have to do is apply the steps above and your problem should be solved. Next time you wanna buy a device, make sure you buy reliable hardware 🙂
