How to use error message
Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed,
begin the diagnosis with the first error code. Whatever causes the first error code may also cause false error
codes. If no error code is displayed, see whether the error symptom is listed in the Symptom-to-FRU
Index for the tablet you are servicing.
Strategy for replacing FRUs for CTO, special bid model, and standard
models
This topic provides information about the model types and FRU identification.
Product definition
This topic introduces different model types and how to identify each type.
Dynamic Configure To Order (CTO)
This model provides the ability for a customer to configure a Lenovo solution from a web site, and have this
configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label and
eSupport will load these products as the 4-character MT, 4-character model and 2-character country code.
The model is “CTO1” and the default country code is “WW” (example: 20AACTO1WW).
Special bid model
This model is a unique configuration that has been negotiated between Lenovo and the customer. A
unique machine type and model (MTM) consists of a 4-character MT, a 4-character model, and a numeric
2-character country code is provided to the customer to place orders (example: 20AA000955). The country
code assigned is numeric and does not designate a specific country or region. The custom model factsheet
for the MTM indicates which country the special bid MTM is set up for. Special bid offering is not generally
announced.
Standard model
Standard models (fixed configuration) are announced and offered to all customers. The MTM portion of the
machine label consists of a 4-character MT, a 4-character model, and an alphabetic 2-character country
code. The country code assigned is alphabetic and represents a designated country or region (example:
20AA0009UK).
FRU identification
Use Lenovo eSupport to identify major FRUs, FRU part numbers, and FRU descriptions for a product at
an MT - serial number level. Examples of major FRUs are hard disk drive, system board, and liquid crystal
display (LCD).
To identify the major FRUs for a product, do the following:
1.
Type
the
Machine
Type
and
Serial
Number
in
the
corresponding
fields.
2.

eSupport also can be used to view the general FRU list for a product. The FRU list is a general list of
components and does not contain specific model information.
