I am still having the issue with this, and as of last week, there was an issue where it would not recover from the HDMI failure. I am about ready just to leave a review and tell people not to purchase this type of system. I see this issue is a recurring theme and now it is impacting my working and testing
Sorry for the trouble.
What is the BIOS version ?
Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of the main page, we will check if you need to update the BIOS.
