Tested 16MB BIOS image for Wistron project Pikachu on board 18730-1M, a Whiskey Lake (WHL) platform, stored in a 15.3 MB RAR. The name gives no laptop brand. Wistron boards use a five-digit number with a suffix, and that suffix identifies the board version, so check it on the PCB. Write the file with an SPI programmer after backing up the existing chip, which may hold serial and network data, and make sure the image matches the 16MB flash.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
