Abstract
Apparatus and method for insuring that a computer is in battery swap mode before a battery thereof is hot swapped by a user is described. A switch is located under the battery receptacle cover, which switch is actuated by the removal of the battery receptacle cover in an amount sufficient to expose the switch. Actuation of the switch generates a battery swap mode ('BSM') signal to the CPU, causing the computer to operate in battery swap mode, at which point the battery may be safely removed without risk of losing data stored in DRAM.
