CRU DEFINITION

Particular hardware related problems with a product (product must be in warranty) can be resolved by replacing parts, which customers can remove and replace by themselves. This process is called Customer Replaceable Unit or CRU. A service part, which can be removed and replaced by a customer, is called Customer Replaceable Unit (CRU) service part. Various levels of difficulty, inidicated with a specific CRU Level ID, are available and located in the service parts list.

The following is a list of the various CRU Level ID types:

CRU Level ID 0  -	Not possible (parts, either not to be replaced by the customer or not installed in the dedicated model)
CRU Level ID 1  -	Possible for all customers (simple to replace parts, requiring few or no tools)
CRU Level ID 2  -	Possible for experienced customers (optional parts, which are slightly more difficult to replace)
CRU Level ID 3  -	Possible for B2B customers with helpdesk (requires trained service personnel)

When installing a CRU, dynabook will send the CRU to you. CRU information and general replacement instructions are shipped with your product, and are available from dynabook at any time upon request.
