Hello Dalchina - you and I worked on this months ago and I think that is when I turned off Windows notifications and it stopped for a while.
Thanks for your suggestion on Chrome - this was one of the many things I tried - I exited the Chrome agent from systray and still had the problem. I even uninstalled Chrome and it still happened so I installed a fresh version of Chrome and keep it updated.
I also updated as many driver updates as I could find at Sony support as well. This is an older VAIO so not many new driver updates available for Win 10 specifically.
The fact the 'problem' is well behaved is of note. It only starts when the laptop is idle for some period and stops when touching keyboard or mouse pad so it is 'behaving normally' for Windows which makes it harder to troubleshoot.
