Make sure the battery to be charged is
installed in either Multi-function bay of
your notebook and connect the AC or
auto/airline adapter.
■
Make sure that the Battery Charging indica-
tor to the left of the Battery Level indicator
of the battery to be charged is visible on the
Status Indicator panel.
■
Make sure the percentage charge is shown
inside the Battery Level icon. (Figure 2-4
on page 21.)
When two Lithium ion batteries are installed,
the charge/discharge rate of the primary and
optional second Lithium ion batteries are the
same,as they are connected in parallel and are
both charging and/or discharging at the same
time. Since the rates are the same, one may
finish charging or discharging before the other
if they were not at the same charge le vel when
they were installed and/or the AC or auto/
airline adapter was connected.
There is no memory effect on the Lithium ion
batteries, which means that you do not need to
discharge them completely before recharging.
A single fully discharged Lithium ion battery
will charge in approximately three (3) hours
when your notebook is Off or in Suspend mode.
The charging time from fully discharged for two
Lithium ion batteries together, is approximately 5
hours when your notebook is Off or in Suspend
mode.Of course partially charged batteries will
not take as long to charge. The charge times will
be significantly longer if your notebook is in use
while the batteries are charging (from approxi-
mately nine (9) hours for one battery to approxi-
mately 15 hours for two batteries with normal
operating levels).

A shorted battery is damaged and must
be replaced so that it does not damage
anything else.
Recharging the Batteries
If you want to ch eck the con d i ti on of ei t h er the
pri m a ry Lithium ion battery or an opti onal sec-
ond Lithium ion battery, ch eck the Ba t tery Level
i n d i c a tors loc a ted on the Status In d i c a tor panel .
These indicators ch a n ge as the battery level s
ch a n ge . Ba t tery 1 is a Lithium ion battery wh i ch
is install ed in Mu l ti - f u n cti on Bay 1 and Ba t tery
2 is a Lithium ion battery wh i ch is install ed in
Mu l ti - f u n cti on Bay 2. ( Fi g u re 2-3 on pa ge 20.)

The Lithium ion batteries are recharged inter-
nally using the AC adapter or auto/airline
adapter. To recharge the batteries:

Using heavy current devices such as LAN
cards or frequent CD-ROM accesses may
prevent charging completely.
