Abstract
A portable computer consists of a base unit within which an electronic unit is housed along with two power supply conductors for the electronic unit. The base unit includes a housing to receive a battery pack with terminals for connection to the power supply conductors. The battery pack contains rechargeable batteries. A power supply control circuit is also connected to the conductors and this includes a recharging circuit. When power is applied via an external socket to the base unit the control circuit and recharging circuit are activated. A sensor device is responsive to the presence of the battery pack to supply the recharging current to the rechargeable batteries. When non-rechargeable batteries are inserted in the housing no recharging current is supplied to them.
