METHOD FOR REDUCING THE NUMBER OF POWER TERMINAL CONNECTORS

摘要

A method for reducing the number of connectors for connecting a tablet unit and a base unit is disclosed. The tablet unit includes a system device and a first connector connected to a power line for supplying power from the base unit. The base unit includes a second connector configured to be connected to the first connector when the base unit is combined with the tablet unit. The tablet unit also includes a battery unit capable of supplying power to the system device through the power line. An external power-supply circuit is also capable of supplying power to the system device from an AC/DC adapter through the power line. Since power can be supplied from the battery unit or the AC/DC adapter to the tablet unit through the power line alone, the number of connector terminals can be reduced.
