Charging the
Battery
NOTE:
With Dell™ ExpressCharge™, when the computer is turned off, the AC adapter charges
a completely
discharged battery to
80
percent in about 1 hour and to
100
percent in approximately 2 hours. Charge time is
longer
with the computer turned on. You can leave the battery in the computer for as long as you like. The battery’s
internal
circuitry prevents the battery from
overcharging.
When
you connect
the
computer
to
an electrical
outlet or install
a battery while
the
computer
is
connected
to
an electrical
outlet, the
computer checks
the
battery charge and temperature.
If
necessar
y,
the AC
adapter
then
charges
the
battery and maintains
the
battery
charge.
If the
battery is
hot from
being used
in
your computer
or
being
in
a
hot
environment,
the
battery
may
not
charge when you connect
the
computer
to
an electrical
outlet.
The
battery is
too hot to
start charging
if the light
flashes alternately green and orange.
Disconnect
the
computer
from the
electrical
outlet
and allow
the
computer and
the
battery
to
cool
to room
temperature.
Then
connect
the
computer
to
an electrical
outlet to
continue charging
the battery.

Before performing these procedures, turn off the computer, disconnect the

CAUTION:
Using an incompatible battery may increase the
risk
of
fire
or explosion. Replace the battery only
with a
compatible battery purchased from Dell. The battery
is
designed to
work with
your Dell™ computer. Do not
use
a
battery from other computers
with
your computer
.

You
must remove all external cables from the computer to avoid possible connector
damage.
