My laptop is an Acer Swift-SF514-52T i7-8550U, 8GB, 256GB, graphics 620,
I usallly run Ubuntu 20.04.2 LTS 64 Bits.
The problem shows up just when I close the lead to send the pc to sleep. after that opening the lead again the screen is already blank and can not be waked up.
So, the only way to continue working is to switch it off and then switch it on again. It looks like is something not going fine in its hardware.
I also work sometimes in Windows 10, the problem is the same blank screen and no way to wake it up.
Thanks a lot for your help.
Thank you for posting on the Intel️® communities.
Using Windows, you can run the Intel® Processor Diagnostic Tool, this will help you determine the processor status or if there is a problem with it:
In Windows 10*, please provide the Intel® System Support Utility (Intel® SSU) results
This will help us determine if this is a problem with the processor/graphics. If you feel this might be an issue with the laptops hardware, you can contact the manufacturer for troubleshooting.

I run the test it looks fine to me, but I've not been able to send the result to you because my system is not smart enough to connect via Wi-Fi to you.
May be I'd missed to tell you that I upgraded my PC from Intel i5 to this i7 mother board processor.
Anyway, thanks a lot for you help.
