Firmware for the Cypress CYPD5225 USB Type-C power delivery controller on board DAY0PAMBAF0, a Quanta-numbered motherboard. The small 128 KB ZIP suits that controller's own flash rather than the main BIOS chip. A corrupted PD firmware often causes no charging or a dead Type-C port, and rewriting it can fix that. Confirm the board number on the PCB, locate the correct PD chip or its flash, read and save the current contents, and use a programmer that supports the part.
