First Claim
Patent Images
1. In a battery-powered computing system, a device for indicating battery charge level, the device comprising:
- calculating means for computing a value related to the level of charge of the battery, the calculating means being operative to distinguish between predetermined operations involving the computing system and being arranged, in computing the value, to take into account the respective effect on battery charge level of each operation actually undertaken by the computing system utilizing a predetermined estimate of that effect to update a previous computation of the value; and
,display means for displaying battery charge level based on the value related to the level of charge of the battery.

Abstract
A battery charge level monitor for a computing system is presented. The monitor stores a value representing the charge stored in a battery. The value is varied to take into account battery charge depletion resulting from operations by the computing system, and to take into account charge added to the battery by a recharger. An operator can access the value through computer commands or by automatic display of the value by the computing system.
