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.
