Solution
This is the lowest battery charge level that your computer
will operate before shutting down. Do not continue using
until you recharge the main battery pack.
Lithium Ion batteries lose about half of their available
capacity after 500 cycles (use and recharge = 1 cycle).
Therefore, a fully charged battery pack after 500 cycles
shows less than four lit LEDs, this is normal. Plan your
charging needs accordingly, and note that the capacity
continues to decrease with each cycle.
Leave the same battery pack in your computer for at least
30 minutes, to allow some time to put some charge into your
backup battery. Then replace the battery pack with a fully
charged pack. Put the original battery pack into an external
battery charger.
