grounded wall outlet.

automatically. If necessary, change the display settings used by
the computer.
Headphones and microphone
One or more 3.5 mm jacks on your computer allow you to connect
audio devices.
Use the headphone port to plug in stereo headphones or powered
speakers; connecting an audio device to the headphone port
disables the built-in speakers.
Use the microphone port to connect an external microphone;
connecting a microphone disables the built-in microphone.
To access the display controls, right-click anywhere on the desktop and select
Display settings.
Some computers have a single "combo" port that allows you to use single-pin
headsets with a built-in microphone. These headsets are most commonly
used with smartphones.
