BIOS image for an Acer Aspire V5-551G, 4 MB, as suggested by the model name; no board number or revision is given. The G suffix denotes the variant with discrete graphics, and the 4 MB size corresponds to a 32 Mbit SPI flash chip. Use it to recover a board that does not post or shows no image after a failed update, writing it with an external programmer such as CH341A or RT809. Back up the original chip beforehand, confirm its capacity, and compare the motherboard number on the PCB with the source unit before flashing.
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 @bios_laptop. Enginerys does not host this file.
