BIOS archive that the name says includes EC firmware, for a board marked 1501B_01_01 with the revision tag SOVP. No laptop brand or model is stated, so match the code against the silkscreen on the motherboard. The 3.41 MB RAR should contain the system BIOS and the embedded controller image, which handles power-on, charging and the keyboard. Flash each file to its matching chip with a programmer, back up both chips before writing, and confirm each image size fits its target flash.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

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 →
