    I think you won't connect this power monitor on your device. My LattePanda can't work once I connecting my usb monitor. However everything works fine for me once I disconnecting the USB monitor. These low coest USB monitor may reduce your power current because of its internal circuit. Make sure you are using a 2A good adapter and quality microUSB cable. Because LattePanda is a computer anyway. It's still power sensitive.

    Do you remember what setting you changed? May be we can simulate it and try figure out how to fix it

    I notice that LattePanda updated a new version bios on their github. Maybe they've improved some bios issues.

    Hi singaii,

    actually you can back up your windows key first before reflashing BIOS. http://www.lattepanda.com/topic-f10t1271.html
