Hi:

What is the full model number or product number of your notebook?

The product number can be found on the same label as the serial number.

Please do not post the serial number.

Or use this guide for how to find that info...

See if this works...

Manually install the latest Intel HD graphics driver as follows...

Download and save the ZIP file version of the Intel graphics driver from the link below.  2nd one down on the left side of the page.

Version: 26.20.100.6912 (Latest)     Date: 6/19/2019

https://downloadcenter.intel.com/download/28888/Intel-Graphics-Windows-10-DCH-Drivers?product=88355

Unzip the graphics driver file to its folder.  Do not do anything with the files in the folder.

Go to the device manager, click on the problem Intel HD graphics adapter.

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option and then at the bottom of that window, select the Let me pick from a list of device drivers on my computer.

Click on Have Disk, and browse to the unzipped graphics driver folder>Graphics>iigd_dch (setup information file), click Next and the driver should install.

Be patient, as it can take a few minutes for the driver to completely install.

When the installation is finished, restart the PC.
