TOPIC



    Upon inserting a fresh battery into my PowerBook 500 series computer, the battery is not immediately recognized. Is this normal?

DISCUSSION


    When a new battery is inserted into a PowerBook 500 series computer, it could take up to 30 minutes (or longer in rare cases) for the battery to be recognized and start to charge. The delay is a result of communication that occurs between the battery and PowerBook. The power circuitry is set up to poll the battery at specified intervals, rather than to communicate immediately after a battery has been inserted.

    This problem has been resolved with the Intelligent Battery Recognition software. This software consists of a system extension and an application which updates the software that is contained on a chip inside the PowerBook 500 series battery. A separate article in the Tech Info Library documents this software, its title is "PB 500 Series: Intelligent Battery Recondition Software (2/95)"
