3 Using an optional external optical drive (select models only) An external optical drive connects to a USB port on the computer and enables you to use optical discs (CDs and DVDs). The computer provides one powered USB port on the left side of the computer. This port provides power to the external optical drive when used with a powered USB cable. An external optical drive connected to the other USB port on the computer must be connected to AC power. An external optical drive, such as a DVD-ROM drive, supports optical discs (CDs and DVDs). These discs store or transport information and play audio and video files. DVDs have a higher storage capacity than CDs. All optical drives can read from optical discs and some drives can also write to optical discs as described in the following table.
