Abstract
Systems and methods for indicating the status of a battery in a portable computing device are disclosed. The methods include retrieving battery status data from a basic input-output system (BIOS) on the computing device, and comparing the retrieved battery status data to a predefined battery status threshold stored on the computing device. Based on the comparison of the battery status data to the predefined battery status threshold, a battery status indicator may be provided to an applications program on the computing device. The battery status data is reflective of a characteristic of the battery, such as battery voltage. A system according to the present invention includes a computer-readable medium having stored thereon computer-executable instructions for performing a method according to the present invention.
