Battery Charging
The battery packs begin charging anytime your computer is connected to AC power
using the AC adapter.
If the standard battery pack is fully discharged and your computer is turned off or in
System hibernate, it fully recharges in about 2.5 hours.
If the standard battery pack is fully discharged and your computer is turned on, the
charging time may vary depending on usage.
If an optional secondary battery pack is installed into the unit bay, it will be charged
together with the standard battery pack. In this case, the standard battery pack is
3
charged first; then, an optional secondary battery pack is charged.
If the standard and an optional secondary battery packs are fully discharged and
your computer is turned off or in System hibernate, they fully recharge in about 5
hours.
If the standard and an optional secondary battery packs are fully discharged and
your computer is turned on, the charging time may vary depending on usage.
Your computer monitors the internal temperature of the unit. If the
unit gets critically hot, battery charging (which generates some heat)
is interrupted until the temperature decreases. This can account for
slightly longer battery charging times.
You can track the charging status of the battery pack using the battery indicator
located next to the power indicator. When the battery indicator is turned on orange,
the battery pack is being charged. When the battery indicator is turned on green, the
battery pack is fully charged.
Or you can use the battery charge indicator located on the corner of the standard
battery pack. There are 5 indicator lamps, and if you press the button under lamps,
they will show you the charging status. If all 5 lamps are lit, the battery is fully
charged. If only an orange lamp is lit, it will discharge soon.
An optional secondary battery pack also has the battery charge indicator. If you
press a white circle, lamps will show you the charging status. The charging status is
same as that of the standard battery.
