Using the Wireless Control
The wireless control allows you to quickly turn all of your wireless radios (Bluetooth ® and
WLAN) off, such as when you are asked to disable all wireless radios on an airplane flight.
Press to turn on all radios. Pressing again returns your wireless radios to
their respective states they were in before you pressed the first time.
Battery Pack
Your laptop is equipped with a high-energy rechargeable lithium ion prismatic (Li-ion) battery
pack. Battery life will vary depending on your laptop configuration, 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.
The 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 five 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.
