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.

Optimising 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 model). • 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.
