The computer will go into sleep/hybernation mode unless turn off/on.
You need to go into the control panel and power setting.
You also need to check the settings for the ethernet adapter and disable "wake on lan" so that when the somputer does try to go into sleep mode it will succeed.
I had a hard time figuring what was going on with my computer after Windows-10 upgrade. However now I have everything figured out and the z800 works great with Windows-10.
