Wireless button

Your computer has a wireless button 1 that will enable or disable
all integrated wireless devices simultaneously. In addition, a
wireless light 2 indicates the computer's overall wireless state
(enabled or disabled). The wireless light does not reflect the
status of individual devices (unless the computer has only one
wireless device). When the wireless light is on, one or more of the
wireless devices are on.
✎
By default, all of the integrated wireless devices and the
wireless light are turned on when you turn on the computer.
✎
The location of the wireless button and light varies by model.
On some computers, the wireless button and light are together;
and on other models, they are separate.
