„ Reading the manuals
Read the supplied manuals before using your computer.
„ Conncting to the power
The built-in battery pack is not fully charged at purchase.
To charge the battery and begin using your computer, connect the computer
to an electrical outlet. The battery is automatically charged while the
computer is running on AC power.
Connecting the computer to an electrical outlet

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.
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:
• If the battery status indicator starts blinking
• If the battery has not been used for a long time
Note:
•
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.
„ Battery Protection
If the battery pack remains idle for a long time, the battery may be
over-discharged, and its degradation speed may be increased. The battery
pack of IdeaPad U series uses the battery protection technology. When your
computer remains idle for a long time, the battery pack enters the sleep mode
to avoid over-discharge. After the battery pack enters the sleep mode, you
cannot turn the computer on without using the power adapter. Please
connect the power adapter to the computer to activate the battery pack.
Note: The batter pack is in the sleep mode by default. When you use the computer for the
first time, please plug the power adapter into it. Otherwise, the computer cannot be
turned on.

„ 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.
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.
Before disconnecting a USB storage device, make sure your computer has
finished transferring data by that device. Click the Safely Remove Hardware
and Eject Media icon in the notification area of Windows to remove the
device before disconnecting.
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.

Chapter 2. Learning the basics
„ Connecting Bluetooth enabled device (on select models)
If your computer has an integrated Bluetooth adapter card, it can connect to
and transfer data wirelessly to other Bluetooth enabled devices, such as
notebook computers, PDAs and cell phones. You can transfer data between
these devices without cables and up to 10 meters range in open space.
Note: The actual maximum range may vary due to interference and transmission barriers. To
get the best possible connection speed, place the device as near your computer as
possible.
Enabling Bluetooth communications on your computer
To enable Bluetooth functions, do one of the following:
• Press
to disable airplane mode.
• Open the charms and select Settings
→
to open the Network configuration page.
Then toggle the airplane mode switch to off.
Note:

•
When you do not need to use the Bluetooth function, turn it off to save battery power.
You need to pair the Bluetooth enabled device with your computer before you can transfer
data between them. Read the documentation supplied with the Bluetooth enabled device
for details on how to pair the device with your computer.
