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.
