Examples of these types of CRUs include an AC adapter, a power
cord, a battery, and a hard disk drive. Other Self-service CRUs
depending on product design may include a memory, a wireless card,
a keyboard, and a palm rest with finger print reader and touchpad.

by an access panel that is typically secured by more than two screws.
Once the access panel is removed, the specific CRU is visible.
