Perform operational charging. If the battery sta indicator or icon does not turn on, remove the and let it return to room temperature. Reinstall pack. If the charge indicator or icon still doe replace the battery pack.
If the charge indicator still does not turn on, system board. Then reinstall the battery pack. I reinstalled battery pack is not charged, go to section.

Note: It takes at least 3 hours to recharg battery pack.
If the voltage is still+11.less0V dcthan after recharging, replace the battery.
4.If the voltage is+11more.0 Vthandc, measure the resistance between battery terminals 3 and
resistance must be 4 to 30 K ohm.
If the resistance is not correct, replace pack. If the resistance is correct, replace board.
