This article describes an approach to charging the battery of battery operated peripherals attached to port- able computers. Provision is made for the peripheral to request a charging cycle to be initiated by the computer via the lines normally used for data communications to the peripheral. This provides a means by which the bat- tery ofthe peripheral becomes a secondaty storage means so that the peripheral never fails to have access to a power supply when connected to a computer which has battery power remaining.
