The heat problem of the Ubook:

As for the heat problem, the laptop is relatively thin, and we have exported the heat of the motherboard to the outer casing to improve heat dissipation, so that the machine can perform better. However, when we use it while charging, we have tested the temperature in the part of the outer casing for about 46 degrees, and there is no hidden danger.
