Optimizing Battery Operation

Battery LEDs

If two battery packs are installed in the computer, they
deplete in parallel. When the battery charge gets low, the
Low Battery indicator above the keyboard turns red.
When the batteries are extremely low, the unit
automatically goes into sleep mode for about five minutes.
During this time, you can replace the batteries one at a
time. To do this, press Suspend. After inserting the
battery, press any key to resume at the point where the
sleep mode was initiated.
There is also a row of four LEDs on the front of each battery
pack. These LEDs indicate the following battery states:
How Many LEDs Lit?

The percentage of power left in each battery. If all four
LEDs light, the battery is at least 76% charged. After
reaching this point, the battery LEDs will then turn
off. If the battery is removed, the LEDs remain lit for
several seconds before turning off (to save the battery
charge).
