Hi DodoGTA. Welcome to the TenForums @

Some devices don't support this sleep state well. It is likely a driver but it could be something more basic with Motherboard.
Myself I would disable Hybrid sleep in Power Options.
You can run an energy report to see if it may give a hint as to the issue. Yours is not so much a sleeping issue, rather it sounds like yours is a waking issue. Some items in report never seem to get resolved but you never know it might just provide a meaningful tidbit.
At a Command Prompt (admin) type the following command
powercfg /energy /output %userprofile%\desktop\Energy.html
(There is a space between the word output and the percent sign.) This will put the energy html report on your desktop. Double click to open.
You might also open the event viewer and look around the exact time you woke your machine. I think the events should be logged right around Event 107, "The system has resumed from sleep". I say around as your issue may be before the system actually records the awaken or it might be after. Hopefully there will be some solid info that you can use to move forward with.
Me, I can be lazy when I want to be, I disabled Hybrid and hibernation.
