Diagnostic Error Code Standardization For 2015 & 2016 Notebook and Tablet systems





This article provides the information on "Diagnostic Error Code Standardization For 2015 & 2016 Notebook and Tablet systems with Skylake, Kaby Lake, Purley and Cherry Trail Chipset Systems".


Diagnostic Error Code Standardization.

Dell has moved to a single error code system across all lines of business. The goal of this standardization is to simplify interpretation of error indications by incorporating the same platform across all Dell system models.

This change is initially applying to Dell Notebook and Tablet systems and will be applied to future Desktop and All In One designs in 2017,
