 Checking battery status

You can determine the percentage of battery power remaining by checking

the battery icon in the notification area.

 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.

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.

Note:

• 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 86 °F (10 °C-30 °C).

• Full charge or discharge is not required.
