Dump of the Realtek RTS5456H USB-C power delivery controller firmware for an HP notebook built on Quanta board DAX8SFMB8B2, packed in RAR with a stated CRC32 of 0xDC2F858C. Quanta numbers boards as DA plus project code plus MB, with the closing characters marking revision, so check the silkscreen before use. Technicians flash this image to the PD controller's SPI chip when a laptop refuses to charge over Type-C or ports stop negotiating power. Back up the existing chip and verify the checksum after writing it.
