Charging the battery
29
Follow these steps again until the battery has been charged and discharged
three times.
Use this conditioning process for all new batteries, or if a battery hasn't been
used for a long time.
Warning: Do not expose battery packs to temperatures below 0° C
(32° F) or above 45° C (113° F). Extreme temperatures may
adversely affect the battery pack.
By following the battery conditioning process you condition your battery to
accept the maximum possible charge. Failure to follow this procedure will
prevent you from obtaining the maximum battery charge, and will also shorten
the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by the
following usage patterns:
• Not discharging and recharging the battery to its extremes, as described
above.
• Frequent use; the more you use the battery, the faster it will reach the end
of its effective life. A standard computer battery has a life span of about
300 charges.
Charging the battery
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.
