HP ProDesk G4 400 won't wake up

HP Recommended
HP ProDesk G4 400
Microsoft Windows 10 (64-bit)

When my computer sleep for longer time than 10 minutes, my system will not wake up from sleep. I can't turn on by pressing power button. I must PC disconnect from the socket for at least 5 minutes and than i can turn on.

 

I tried to disable hybernation by powercfg -h off.
 
Can anyone help me?
 
Thanks
