DIAGNOSTIC TESTS and ERROR MESSAGES
A number of communication and battery data examination tests are run
when an Intelligent Battery is inserted into the PowerBook computer.
Similar tests are run by the PowerCenter to assure the battery is in
proper condition to proceed with a charge or use cycle. The tests can
require as little as 3 seconds for a good battery and as long as 15
minutes for a battery that has over discharge and /or shorted cell
problems.
Some users may use the PowerCenter to test batteries to assure they
are communicating and to accurately determine their charge status in
percent of the normal maximum.
The Lind Battery Utilities 500 program runs an expanded set of diag-
nostic tests that examine data stored in the battery and gives the user
options for correcting data or control parameters that are not in the
normal range. See the BU-500 manual for further details.
NOTES
1- Proceed with charging or use.
2- If no communication, proceed with reset or recovery tests.
3- If successful, communication is established and tests continue.
4- Normal charging will proceed.
5- A high battery temperature will prevent or stop charging.
6- Charging will be terminated with this test failure.
7. A PowerBook must be connected to the PowerCenter to allow calibration
discharge cycles to begin.
8. ‘Ex’ error codes are canceled only by removing the battery from the PowerCenter.
