To ensure that
thebattery
marntains
its maximum
cap
acrty,
operate
the
computer on
battery
pow
er
at
least once
a
month.
The
Lithium-
Ion battery
has
no
memory effect
so
it
is
not
necessary
to let
the
battery
fully
discharge
each
time.
However,
for better
accuracy
of
the
battery meter,
it
is
helpful to
fully
discharge the battery
periodically.
Please see
"Maintaining
your battery"
on page
16
fot
procedures.
If
the computer is
continuously operated on
AC power,
either
through
an
AC
adaptor
or
a
port replicator
(if
applicable to
your
system),
for
an
extended
period
(more than
a
month),
the
battery may
fail to retain a
charge.
This may shorten the
life
of
the
battery, and
may
cause
the
battery meter to be
inaccurate.
The
computer also has
an
internal real-time-clock (RTC)
battery.
The
RTC battery powers the
RTC memory that
stores
your
system
configuration
settings and the current
time
and
date
information.
It
maintains this information
for
up
to
a
month
while
the
computer
is
turned
off.
TECHNICAL NOTE Depending on your system, the
RTC
battery may
only
charge while the computer is turned
on.
Battery life and charge
time
may
vary, depending upon
power
management settings, applications and features
used.
