BatteryMAX (idle detection)
BatteryMAX is an Idle Detection System used for computer power management developed at Digital Research, Inc.'s European Development Centre (EDC) in Hungerford, UK. It was invented by British borne engineers Roger Gross and John Constant in August 1989 and was first released with DR DOS 5.0 . It was created to address the new genre of portable personal computers (lap-tops) which ran from battery power. As such, it was also an integral part of Novell's PalmDOS 1.0 operating system tailored for early palmtops in 1992.
