Thank you for your response.
The power option indicated that my screen time before it went to sleep was too long. This has no relevance to my current problem.
The system maintenance indicated on no issues present.
Any suggestion?
Btw, for some reason the search bar is not working properly, and I found the troubleshooting in control panel. In addition, I'm having a problem with runtime broker using a lot of system resources. Not sure if these issues affect each other and the battery
drain while on sleep mode.
I must admit that the upgrade to win 10 on both my tablet and laptop was not a pleasant experience, and still isn't ...
Best,
