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 computer models.
This change is initially applying to Dell Laptops and Tablets and will be applied to future Desktop and All In One designs in 2017.
The tables below will define the LED/Beep codes for Dell Notebook and Tablet systems:
| Form-Factor Specific Error Codes - Hardware Controlled | |||||
