System Board (Motherboard)
The Caps Lock blink code is triggered by the Embedded Controller (EC) when it detects a failure during the Power-On Self-Test (POST) sequence. On Envy x360 models, this typically signifies a critical failure in the system board's ability to initialize the BIOS or a failure in the power rails supporting the integrated processor. Replacing the system board resolves faults in the EC, BIOS ROM, and soldered memory modules simultaneously.

DDR4/DDR5 SODIMM Memory Module
A 3-slow, 2-fast blink pattern specifically identifies a memory initialization error. If the specific Envy x360 variant utilizes removable SODIMM slots rather than soldered RAM, a faulty or improperly seated memory module will prevent the CPU from accessing the temporary storage required to load the operating system, resulting in a black screen.

AC Power Adapter (65W/90W)
In some forensic cases, an unstable or under-voltage power supply prevents the motherboard's power management IC from reaching the 'Power Good' state. This stall in the power sequence can cause the EC to halt and output a generic blink code as it fails to receive the necessary voltage stability to proceed with the CPU handshake.
