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 co mputer, and connect to a mains p ower 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 d ay. Allowing
the battery to charge 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 your battery for on-the-go use.
•Eject a PC card if it is not being used, as it will continue to draw power.
•Store the battery pack in a cool, dry place. The recommended temperature is 10°C
to 30°C. Higher temperatures cause the battery to self-discharge faster.
•Excessive recharging decreases the battery life.
•Look after your AC adapter and battery. See, "Taking care of your AC adapter,"
and, "Taking care of your battery pack."
Battery-low warning
When using battery powe r 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 dep leted and the
computer shuts down.
