Appendix A
A: After portable computers have not been used for a long time (more
than one month), the batteries will go into the low voltage protection
mode due to data back-ups and natural electrical discharge. At that
point, restoring normal voltage will require slow charging over a period
of several hours. Calibration can be performed after the battery has
returned to a normal condition.
