Operating on battery power38
English
Use this conditioning process for all new batteries, or if a battery hasn't been used for a
long time. If the computer is to be stored for more than two weeks, you are advised to
remove the battery pack from the unit.
Warning: Do not expose battery packs to temperatures below 0°C (32°F) or
above 60°C (140°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:
• Using the computer on constant AC power with the battery inserted. If you want
to use constant AC power, you are advised to remove the battery pack after it is
fully charged.
• 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 lifespan of about 500 charges.
Installing and removing the battery pack
Important! Before removing the battery from the unit, connect the AC adapter if
you want to continue using your computer. Otherwise, turn off the computer
first.
To install a battery pack:
1 Align the battery with the open battery bay; make sure that the end with the
contacts will enter first, and that the top surface of the battery is facing up.
