RAR archive for the HP EliteBook 840 G2, labelled with a 25L128 flash, which points to a 128 Mbit (16 MB) SPI chip of the MX25L128 type. At 6.01 MB compressed, it most likely holds a full BIOS dump for that chip, though the contents should be checked after unpacking. Write it with a CH341A or similar programmer to restore a board that fails to start. Read and save the original chip first and make sure the image is exactly 16 MB.
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 @SCHEMATICWORLD. Enginerys does not host this file.
