Episode 68: Motherboard Issues — POST Codes, No Power

This episode targets one of the most frustrating and high-stakes categories of hardware failure: motherboard issues. We begin with POST codes and beep sequences, explaining what each code represents and how to interpret them using manufacturer reference charts. Then we move on to diagnosing systems that show no power at all—walking through the role of power connectors, voltage regulation modules, and power button wiring.

We also examine symptoms like bloated capacitors, burnt traces, or failed onboard components that may not trigger any diagnostics but still render a board inoperable. These issues are common in both desktop and laptop repair scenarios, and you’re likely to face related questions on the A Plus exam. This episode equips you to identify symptoms accurately and determine the most logical next step. Brought to you by BareMetalCyber.com.
