EC firmware binary for an Acer laptop on the Quanta DA0Z09MBAHO board, revision H, in a 1.73 MB ZIP. The DA0...MB pattern is Quanta's motherboard numbering. The embedded controller manages power-on, charging and keyboard, so a corrupted EC image can cause a dead or non-charging unit. Flash it with an SPI programmer after reading and saving the original chip. A matching BIOS file for the same board exists separately; confirm the revision on the PCB first.
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.
