Chapter 2. Learning the basics
Using AC adapter and battery ----------------------------------------------------------
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
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 86 °F (10 °C-30 °C).
•Full charge or discharge is not required.

Connecting USB devices
You can connect a USB device to your computer by inserting its USB plug
(Type A) into the USB port on your computer.
The first time you plug a USB device into a particular USB port on your
computer, Windows automatically installs a driver for that device. After the
driver is installed, you can disconnect and reconnect the device without
performing any additional steps.
Before disconnecting a USB storage device, make sure your computer has
finished transferring data by that device. Click the Safely Remove Hardware
icon in the notification area of Windows to remove the device before
disconnecting.
Note: Typically, Windows detects a new device after connecting it, and then installs the
driver automatically. However, some devices may require you to install the driver
before connecting. Check the documentation provided by the device’s manufacturer
before connecting the device.
Note: If your USB device uses a power cord, connect the device to a power source before
connecting it. Otherwise, the device may not be recognized.
