      Supported Batteries

      This is not an urgent update; the problem will manifest itself over a period of months. Eventually, the battery will erroneously indicate that it can no longer hold any charge, but this effect is slow and accumulating. Large enterprise customers can plan to do this update during their next planned system maintenance.

      The battery firmware update is applicable to the FRU part numbers shown below. The battery firmware update will change the FRU number electronically stored in the battery (which is reported by Power Manager). This is done as one way to confirm that the battery firmware update has been completed. Obviously, the printed label will still show the "old" FRU number.

      • FRU P/N : 42T4708 (ASM P/N : 42T4709)

      Notes

      • To enable the battery to indicate accurate state of charge and correct battery health, do the following procedures after the battery firmware update by this software.

      [Windows 8]

      • After updating firmware, reset the battery gauge for calibration, as follows.
        1. Have your battery 100% charged.
        2. Discharge it until 5% battery charge. Do NOT attach the AC adapter to the computer during discharge.
        3. Have it 100% charged, again. Do NOT detach the AC adapter from the computer during charge.

      [Windows 7/Vista/XP]

      • Reset the battery gauge only once for calibration. For details, refer to the Resetting the battery gauge of Manual Update in the UPDATING THE BATTERY FIRMWARE section below.
