CRU; two asterisks (**) means that the part is an Optional-service CRU.
ThinkPad computers contain the following types of CRUs:
Self-service CRUs
These CRUs unplug or are held by no more than two screws.
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.
Optional-service CRUs
These CRUs are isolated parts within the computer that 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.
v
A RoHS compliant FRU is identified by an R. An N in the RoHS ID column
