Hello,
Could you please help to find BIOS for Hi10 HiBook Q64G45160400594 Model:CWI514?
BIOS wasn’t updated till 2016
And what is correct name of the device?

This bios have no win key and serial number. If you need original key contact aftersale@chuwi.com

I have problem with power management system: the unit shutting down if unplug. Does the updated BIOS solve the problem?

More likely no than yes.
