Realtek RTS5452H PD firmware for position U9 on a WIN4 device with the 6800U processor variant, as the name states, supplied as zip with CRC32 0x9E21AA57. Since boards may use separate controllers per Type-C port, each designator needs its own matching image. A corrupted dump typically leaves one port without charging or data. Flash the controller's SPI chip with a programmer after reading the original, and verify against the checksum. Confirm the CPU variant and reference designator on your board before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosdumpcomputer. Enginerys does not host this file.
