Looking Up Fru Information - Lenovo 10AQ Maintenance Manual

The following table lists the major FRUs shown in "Locating major FRUs and CRUs" on page 78 and
identifies which FRUs also are self-service CRUs or optional-service CRUs.
Notes:
• Self-service CRUs: These CRUs unplug or are secured by no more than two screws. Examples of
these types of CRUs include the keyboard, the mouse, any USB device, and the power cord. Other
self-service CRUs depending on product design might include memory modules, adapter cards, hard
disk drives, and optical drives.
• Optional-service CRUs: These CRUs are isolated parts within the computer and are concealed by an
access panel that is typically secured by more than two screws. Once the access panel is removed, the
specific CRU is visible.
