Lenovo USB-C PD controller dump from LCFC board NM-E141, with a generic RTSx code label indicating a Realtek RTS-series chip and a CRC32 of 0x3020736C for verification. LCFC, Lenovo's in-house ODM, prints NM-xxxx codes on its boards, so check yours matches. When a machine charges only through the barrel jack or not at all over Type-C, reprogramming the PD chip's small SPI flash is a standard fix. Extract the RAR, read and keep the original image, then write and verify with your programmer.
