Surface Pro 7 simply switches off
Users of a Microsoft Surface Pro 7 suffer from the problem that the devices switch off spontaneously. This Microsoft Answers forum thread describes the sporadic but non-reproducible shutdown. I had already reported this problem in February 2020 in the blog post Surface Pro 7 shutting down randomly. In comments like these, people are annoyed by the behavior. The causes are unknown, and workarounds I described in the blog post do not work for all users.
Proposal for a workarounds
About Barb Bowman, who is a community moderator on the Microsoft Answers forum, I got aware of this forum thread. After the problem has been discussed for a while, user CM_TX has written together the well-known workarounds that have helped him.
Option 1: Remove "Modern Standby" features and create a new (non-balanced) power plan:
- Open the Registry Editor and navigate to "HKEY_LOCAL_MACHINE\SYSTEM\
- Change the "CsEnabled" value from '1' to '0'. Click OK and restart the Surface Pro.
- Create a new power plan using one of the newly available plan options. (I chose "High performance" and didn't bother changing any of its settings.)
Option 2: Change the display drivers to the Microsoft Basic Display Adapter:
- Open the Device Manager.
- Expand "Display Adapters".
- Right-click on "Intel(R) Iris(R) Plus Graphics" and select "Update driver".
- Choose "Browse my computer for driver software".
- Choose "Let me pick from a list of available drivers on my computer".
- Select "Microsoft Basic Display Adapter" and click Next to install the drivers.
Option 3: Update the display drivers to the latest version (from Intel, not Microsoft):

- Download the latest display drivers from Intel as a ZIP file: https://downloadcenter.
- Extract the files from the ZIP file to a local folder.
- Open the Device Manager.
- Expand "Display Adapters".
- Right-click on "Intel(R) Iris(R) Plus Graphics" and select "Update driver".
- Choose "Browse my computer for driver software".
- Choose "Let me pick from a list of available drivers on my computer".
- Select the "Have Disk" button and browse to the folder containing the extracted files.
- In the "Graphics" subfolder, select the file "iigd_dch.inf" and click OK.
- Click Next to install the latest Iris Plus drivers. (This also installs the Intel Graphics Command Center application by default.)
The user wrote, that for him – and many other affected persons – the option 4 described below was helpful:
Option 4: Disable the "Panel Self Refresh" option in the Intel Graphics Command Center:
"I've fixed it on my SP7 i5/8G/256G by installing the Intel Graphics Command Center from the Microsoft Store, opening it, going to System>Power>Panel Self Refresh and turning it off for both "On Battery" and "Plugged In"."
Maybe it'll help you when you're affected. Microsoft is investigating the problem and there might be a solution sometime.
