I have 125 Fujitsu Stylistic 3400's.
They have two different numbers that identilfy them, CPO33400-01 and CPO33400-02.

A client is claiming they "electronics" internally are different even though they have the same configurations.

Does anyone have an idea what may be different. Could it be the Bios?
If so can this be changed without dealing with Fujitsu who can't seem to answer the question.

Thank you!!
