Realtek RTS5450 USB-C power delivery controller firmware for a Xiaomi laptop, supplied as a 44.7 KB RAR archive. The name marks the dump as OK, meaning reported working, and adds the tag blue, which likely distinguishes it from another variant though the name does not explain it. A dump like this is written to the small SPI flash beside the PD controller when Type-C charging or negotiation has failed. Back up the existing chip before writing and check that the exact Xiaomi model matches your board.
