Battery pack
The computer uses a battery pack that gives you long use between charges.
Battery pack characteristics
The battery pack has the following characteristics:
• Employs current battery technology standards.
• Delivers a battery-low warning.
The battery is recharged whenever you connect the computer to the AC
adapter. Your computer supports charge-in-use, enabling you to recharge the
battery while you continue to operate the computer. However, recharging with
the computer turned off results in a significantly faster charge time.
The battery will come in handy when you travel or during a power failure. It is
advisable to have an extra fully charged battery pack available as backup.
Contact your dealer for details on ordering a spare battery pack.
Maximizing the battery’s life
Like all other batteries, your computer's battery will degrade over time. This
means that the battery's performance will diminish with time and use. To
maximize your battery's life, you are advised to adhere to the recommendations
set out below.
Conditioning a new battery pack
Before you use a battery pack for the first time, there is a conditioning process
that you should follow:
1 Insert the new battery without turning the computer on.
2 Connect the AC adapter and fully charge the battery.
3 Disconnect the AC adapter.
4 Turn on the computer and operate using battery power.
5 Fully deplete the battery until the battery-low warning appears.
6 Reconnect the AC adapter and fully charge the battery again.
Follow these steps again until the battery has been charged and discharged
three times.
Use this conditioning process for all new batteries, or if a battery hasn't been
used for a long time. If the computer is to be stored for more than two weeks,
you are advised to remove the battery pack from the unit.
23
English
Warning: Do not expose battery packs to temperatures below 0° C
(32° F) or above 45° C (113° F). Extreme temperatures may
adversely affect the battery pack.
By following the battery conditioning process you condition your battery to
accept the maximum possible charge. Failure to follow this procedure will
prevent you from obtaining the maximum battery charge, and will also shorten
the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by the
following usage patterns:
• Using the computer on constant AC power with the battery inserted. If you
want to use constant AC power, you are advised to remove the battery
pack after it is fully charged.
• Not discharging and recharging the battery to its extremes, as described
above.
• Frequent use; the more you use the battery, the faster it will reach the end
of its effective life. A standard computer battery has a life span of about
300 charges.
Installing and removing the battery pack
Important! Before removing the battery from the unit, connect
the AC adapter if you want to continue using your computer.
Otherwise, turn off the computer first.
To install a battery pack:
1 Align the battery with the open battery bay; make sure that the end with
the contacts will enter first, and that the top surface of the battery is
facing up.
2 Slide the battery into the battery bay and gently push until the battery
locks in place.
To remove a battery pack:
1 Slide the battery release latch to release the battery.
2 Pull the battery from the battery bay.
24
English
Charging the battery
To charge the battery, first make sure that it is correctly installed in the battery
bay. Plug the AC adapter into the computer, and connect to a mains power
outlet. You can continue to operate your computer on AC power while your
battery is charging. However, charging the battery with the computer turned
off results in a significantly faster charge time.
Note: You are advised to charge the battery before retiring for
the day. Charging the battery overnight before traveling enables
you to start the next day with a fully charged battery.
Checking the battery level
The Windows power meter indicates the current battery level. Rest the cursor
over the battery/power icon on the taskbar to see the battery's present charge
level.
Optimizing battery life
Optimizing battery life helps you get the most out of battery operation,
prolonging the charge/recharge cycle and improving recharging efficiency. You
are advised to follow the suggestions set out below:
• Purchase an extra battery pack.
• Use AC power whenever possible, reserving battery for on-the-go use.
• Eject a PC Card if it is not being used, as it will continue to draw power (for
selected models).
• Store the battery pack in a cool, dry place. The recommended temperature
is 10° C (50° F) to 30° C (86° F). Higher temperatures cause the battery to
self-discharge faster.
• Excessive recharging decreases the battery life.
• Look after your AC adapter and battery.
Battery-low warning
When using battery power pay attention to the Windows power meter.
Warning: Connect the AC adapter as soon as possible after the
battery-low warning appears. Data will be lost if the battery to
become fully depleted and the computer shuts down.
25
