Checking battery status
You can determine the percentage of battery power remaining by using Windows Power
Options.
Charging the battery
When you find that the battery power is low, you need to charge the battery or replace it with a
fully charged one.
The battery is charged when the AC adapter is connected to the computer and the battery is
installed.
Charging time will depend on the usage environment.
You need to charge the battery in any of the following situations:
• When you purchase a new battery
• If the battery status indicator starts blinking
• If the battery has not been used for a long time
Removing the battery pack
If you are not going to use the computer for an extended period of time, or if you need to send
your computer to Lenovo for service, etc. remove the battery pack from the computer. Before
removing the battery pack, make sure the computer has been shut down.
Note: As each computer user has different habits and needs, it is difficult to predict how long a battery
charge will last. There are two main factors:
• The amount of energy stored in the battery when you commence work.
• The way you use your computer: for example, how often you access the hard disk drive and how
bright you make the computer display.
Notes:
• You are advised to insert the battery pack when using your computer to prevent small particles from
entering the inside of your computer.
• To increase the life of the battery pack, the computer does not start recharging the battery immediately
after it drops from fully charged.
• Charge the battery at a temperature between 50 °F and 80 °F (10 °C-30 °C).
• Full charge or discharge is not required.
