Appendix D. Customer replaceable units (CRUs)

Your computer contains the following types of internal CRUs:

•Internal CRUs (located behind an access panel): These CRUs are isolated parts within the computer that are concealed by an access panel that is typically secured by either one or two screws. Once the access panel is removed, only the specific CRU is visible. Examples of these types of CRUs include memory modules and hard disk drives.

•Internal CRUs (located within the product): These CRUs are accessible only by opening the computer’s outer case. Examples of these CRUs include PCI Express Mini Cards and the integrated keyboard.
