What does a POST error code of 9xx indicate?

A POST (Power-On Self-Test) error code in the 9xx range typically indicates an issue related to the motherboard or its connected components. When the system first powers on, the POST process checks various hardware components to ensure they are functioning correctly before loading the operating system.

The specific codes can vary by the motherboard manufacturer, but generally, the 9xx codes are associated with hardware problems detected in the system's setup or initial hardware checks. This could include issues with communication between the motherboard and the RAM, CPU, or other critical components.

In the context of the provided answer, a problem specifically attributed to the printer would not typically cause a POST error. Instead, such issues are usually related to peripheral devices and would not be involved in the initial hardware diagnostics performed during the POST process.

Understanding POST error codes is essential in computer hardware diagnostics, as they guide users on what components to check or troubleshoot when a system fails to start correctly.
