Laptop touchscreen doesn't function after wake up.

[Gad-Westy]

My Dell 5530 has a 4k touchscreen. If it goes to sleep/hibernate the touchscreen will not function once woken. It works fine if I restart the computer fully.

So far, I've tried updated the bios to latest version but no joy. Running windows 10.

Any pearls of wisdom?

I had a similar issue with a Lenovo and the Bluetooth adapter. I solved it by disabling power management or something similar in device manager. Perhaps try that in usb or hid devices ??

I know how it feels 😉

Cheers folks. Don't seem to have any power options for the touchscreen. It's under human interfaces rather than USB and doesn't seem to have the same options as USB devices.

Have a look in the BIOS for S3 and S5 wake-up, possibly under power or sleep settings. Both are 'on' in my Dells.
