Abstract
A power management scheme for a computer system prioritizes battery charging. The scheme includes determining when the output of a power adapter, which powers a computer and a battery subsystem, has reached or is about to reach a threshold which may be the power budget for the computer system. When this happens, rather than throttling battery charging, the system throttles back an aspect of the computer. Alternatively, after the computer has been throttled back, if the power budget still is being exceeded or is about to be exceeded again, then battery charging can be throttled back. In yet another embodiment, battery charging can be throttled first, followed, if necessary, by computer throttling.
