Battery pack
The computer uses a battery pack that gives you long use between charges.
Battery pack characteristics
The battery pack has the following characteristics:
• Employs current battery technology standards.
• Delivers a battery-low warning.
The battery is recharged whenever you connect the computer to the AC
adapter. Your computer supports charge-in-use, enabling you to recharge the
battery while you continue to operate the computer. However, recharging with
the computer turned off results in a significantly faster charge time.
The battery will come in handy when you travel or during a power failure. It is
advisable to have an extra fully charged battery pack available as backup.
Contact your dealer for details on ordering a spare battery pack.
Maximizing the battery’s life
Like all other batteries, your computer's battery will degrade over time. This
means that the battery's performance will diminish with time and use. To
maximize your battery's life, you are advised to adhere to the recommendations
set out below.
Conditioning a new battery pack
Before you use a battery pack for the first time, there is a conditioning process
that you should follow:
1
Insert the new battery without turning the computer on.
2 Connect the AC adapter and fully charge the battery.
3 Disconnect the AC adapter.
4 Turn on the computer and operate using battery power.
5 Fully deplete the battery until the battery-low warning appears.
6 Reconnect the AC adapter and fully charge the battery again.
