Notes: 
v   
 Each FRU is available for all types or models, unless specific types or models 
are specified. 
v 
 
 FRU with specific models listed and described as xxU (where U is an example 
of a country designator) should be used for all models ending in U. 
v 
 
 FRU with specific models listed and described as 3Dx (where 3D is an 
example of a unique configuration) should be used for all of these models, 
unless specific country or region designator is specified. 
v 
 
 A CRU (customer replaceable unit) is identified by a single asterisk (*) or two 
asterisks (**) in the CRU ID column. An N in the CRU ID column means that 
the part is not a CRU. A single asterisk (*) means that the part is a Self-service 
CRU; two asterisks (**) means that the part is an Optional-service CRU. 
Lenovo 3000 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 
means the part is not a RoHS compliant FRU. 
v 
 
 FRUs marked with 
OP are available as options.
