Charging the Battery Pack

Charging the Battery Pack
Note:
For more information on maintaining
your battery packs, see page 4-4.
The battery pack can be charged with the AC Adapter. You must
charge the battery pack in any of the following situations:
• A new battery pack was purchased.
• The battery status indicator (orange) is blinking, and the
computer beeps four times.
• The battery status indicator (orange) blinks for less than 1
minute.
Charging with the AC Adapter
Note:
Battery packs shipped from the
factory are in an almost-discharged
state, so you must charge them fully
before use.
The following table shows the approximate charging times for the
battery pack:
Conditions Charging Time
Operational charging 6 to 8 hours
Power-off charging 2 hours
If the battery pack is new or has not been used for a long period of
time, it does not reach full charge with only one charging. This is
normal. When used regularly (at least once per week) and properly
(as described on page 4-4), the battery pack will work its way back
up to full capacity within five or six charge and discharge cycles.
