Checking battery status

You can determine the percentage of battery power remaining by checking the battery icon in the notification area.

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.

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

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 86 °F (10 °C-30 °C).

•Full charge or discharge is not required.
