2. Then confirm that the parameters shown in the screen for Current Power Source and Total
Battery Power Remaining are correct.
3. Repeat the step 1 and step 2 for both battery and adaptor.
From hardware, this helps to identify whether you should replace the battery pack or not.
1. Power off the system.
2. Remove the battery pack and measure the voltage between terminals one (+) and seven (-).
There are seven terminals totally. See the illustration below.
3. If the voltage is still less than 7.5V after recharging, replace the battery.

returns to room temperature, reinstall it to the system.
If the charge indicator does not light up, replace the battery pack. If the charge indicator still does
not light up, replace the AC/DC charger board.
