Using the Integrated Camera

Turning the Camera On and O

Press the key combination <Fn><F9> to switch on or switch o the camera. After
switching on the camera, you need to activate its function through the Microsoft
Windows operating system. In addition, you can also use Windows Movie Maker
to create, edit, and share videos.
Using the Wireless Control
e wireless control allows you to quickly turn all of your wireless radios
(Bluetooth® and WLAN) o, such as when you are asked to disable all wireless
radios on an airplane ight. Gently touching this control one time turns all of your
radios o. Gently touching it again returns your wireless radios to their respective
states they were in before you touched the control the rst time.
Battery Pack
Your laptop is equipped with a high-energy rechargeable lithium ion (Li-ion)
battery pack. Battery life will vary depending on your laptop conguration, model,
applications installed, power management settings, and features used. As with
all batteries, the maximum capacity of this battery will decrease with time and
usage.
e battery meter lights on the battery pack indicate the charge level of the
battery. When you press the battery meter once, the charge level lights illuminate.
Each of the ve lights represent approximately 20% of the total battery charge.
For example, if four lights turn on, there is 80% of battery charge remaining and if
no lights turn on, there is no charge remaining in the battery.
Power Management

Understanding Power Consumption

In order to fully utilize the power of your battery, it would be a good idea for you
to spend some time acquiring a basic understanding of the power management
concept from your operating system.
You can use the power options in your operating system to congure the power
settings on your computer. e Microsoft® Windows® operating system installed
on your computer provides three default options:
Balanced — Oers full performance when you need it and saves power •
during periods of inactivity.
Power Saver — Saves power on your computer by reducing system •
performance to maximize the life of the computer and by reducing the
amount of energy consumed by your computer over its lifetime.
High Performance — Provides the highest level of system performance •
on your computer by adapting processor speed to your activity and by
maximizing system performance.
