We believe that we have solved the problem -- It certainly was not straight forward, but it seems to have worked (4 laptops were affected and all seem to be working now) - We needed to download a chipset and then download drivers.

2026-07-20T16:42:32.7866667+00:00 Thank you, Joan. By any chance, did you ask Acer support? They might have data on if multiple people are having this issue and a fix using a driver is in the works.

2026-07-20T02:48:48.5166667+00:00 I see, thank you.
On a test machine, let me verify if the problem arose with the update last week.
To remove the most recent update, please follow these steps to access the Windows Recovery environment:
- Open the Settings app by pressing the Win + I keys.
- Navigate to System > Recovery.
- Click the ""Restart Now"" button next to Advanced Startup.
- Choose the Troubleshoot option.
- Select ""Uninstall Updates,"" then choose either ""Uninstall Latest Quality Update"" or ""Uninstall Latest Cumulative Update.""
Allow the process to complete.
I look forward to hearing from you to get the results of the troubleshooting.
