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.
