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 life span of
about 300 charges.
Replacing the battery pack
The notebook uses lithium batteries. Replace the battery with the same
type as that which came bundled with your product. Use of another battery
may present a risk of fire or explosion.
Warning: Batteries may explode if not handled properly. Do not
disassemble or dispose of them in fire. Keep them away from
children. Follow local regulations when disposing of used
batteries.
Installing or 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.
