Exploring Your Computer's Features Using tablet mode 121 Using external speakers or headphones Your computer is equipped with a full stereo sound system with an internal speaker. Instead of using the internal speakers, you can connect headphones or a pair of external stereo speakers. Before putting on headphones to listen, turn the volume down. Do not set the volume too high when using headphones. Continuous exposure to loud sound can harm your hearing. TECHNICAL NOTE: When using amplified speakers, use speakers that require an external power source. Other types of speakers will be inadequate to produce sound from the computer. To play back sound files through external speakers or headphones: 1 Locate the headphone jack on the computer. 2 Using any necessary adapters, plug the cable from the headphones or external speakers into the headphone jack. The headphone jack requires a 16-ohm stereo mini-jack. To adjust the volume: ❖ For external speakers, use the volume controls on each speaker with the computer's volume control knob. ❖ For headphones, use the computer's volume control dial. Using tablet mode One of your computer's features is a convertible display that allows you to use the screen much as you would a writing tablet. Your computer came with applications already installed specifically designed to work with the tablet feature of the system. For more information on those applications, see the documentation provided with them. Preparing to use the tablet 1 Lift the display panel. 2 Press and hold the power button until the on/off light on the system indicator panel glows blue, depending on your model-about one second. 3 Rotate the display panel clockwise 180o (degrees). When you complete this task, the screen faces away from the keyboard.
