 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

If the battery power is low, you need to charge the battery.

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:

• 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.
