The CM-4 94V-0 (often paired with the code E162264) is a generic motherboard or sub-board marking rather than a specific model name. These boards are widely used by manufacturers like Lenovo, HP, and HannStar in laptops (e.g., Lenovo IdeaPad 330S) and tablets (e.g., Essentiel B smart tab 8004).
In some cases, the CM-4 module itself has a damaged power rail. While the module’s internal boardview is proprietary, community-driven boardviews exist for the CM-4 base PCB, showing the location of the MXL7704 PMIC, the BCM2711 BGA, and the DDR4 RAM chips. cm-4 94v-0 boardview

"CM-4 94V-0" typically refers to a manufacturer's code for a PCB's substrate material and flame-retardant rating (UL 94V-0) rather than a specific motherboard model. Because of this, "helpful papers" or boardviews depend on identifying the actual device, such as a laptop (HP/Clevo) Raspberry Pi Compute Module 4 Resources for "CM-4 94V-0" Hardware 1.
