Zipped firmware for the Realtek RTS5457V USB-C PD controller found on Lenovo board NM-E541, an LCFC design. The name carries no version or checksum. Technicians reach for such dumps when a notebook ignores Type-C chargers, negotiates only 5 V or loses USB-C display output after a fault. Program the SPI flash linked to the controller with a hardware programmer, having first saved the original contents. Confirm the NM number printed on the PCB matches, because firmware from a different board can leave ports non-functional.
