When I put my Windows 10 PC into Sleep mode, it stays there for about five minutes. The PC then momentarily wakes up by itself (for about five seconds) and then goes into Hibernate mode, (the sleep indicator stops flashing). This has suddenly started happening and is not coincident with any update or download. I have tried Chat lines with Microsoft Techs. and every possible combination of Power Management options, all of no avail. sfc/scan shows no problems. Wake timers have been disabled, and there are no devices allowed to wake the PC up. I can still wake from Hibernate with no problem, the annoying difference is the lack of the flashing Sleep mode indicator.

Anyone got any possible solutions. I draw the line at reinstalling drivers as I am not that competent.
