When reinstalling the battery connector/cable, placement of the connector is critical. If the connector isn't positioned accurately, contact with the battery terminals won't be completed. The battery connector cover will help you align the connector, but there will still be a little leeway as you screw the cover down. Position the battery first, to adjust the connector's position; then remove the battery and tighten the cover screws down. You may even want to try plugging the computer into the AC charger before completing the cover attachment, to ensure that battery is charging and the connector is correctly positioned.
