To remove a battery pack:
1
Slide the battery release latch to release the battery.
2 Pull the battery from the battery bay.
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.
