HP 15-e015TX BIOS archive for the Quanta board DA0R62MB6E0, with the name also listing the KB3940Q embedded controller and the A1 marking, packed as a 3.42 MB RAR. DA0...MB...0 is Quanta's board numbering pattern. The KB3940Q reference suggests EC firmware may be relevant on this design, so check the contents. Flash it to the SPI chip with a programmer to recover a bricked board. Back up the original chip first and verify the board number and size match.
