I got a new computer (Z240 SFF Workstatiion) and just update window 7 to window 10 . The only problem here is the computer do not want to sleep. I shut down my computer. After the computer totally off about a few minute. It wake up again. It show there is no window operating system. No boot device found. Next time i shut down, i will off the main power.
I called HP for help for my case. They replied they don't see there is any thing here.....
Anyone can help me?
Thank you.
