Most manufacturers, including Acer, distribute BIOS updates as Windows executable files ( .exe ) or DOS-based packages. These are designed for users to flash the BIOS from within Windows or a bootable USB stick. However, if a laptop is "bricked" (won't POST), you cannot run an .exe file.
If extraction fails, do not panic.

If a simple extraction doesn't work, try opening the .exe directly inside the 7-Zip interface to browse its internal file structure. acer bios extractor tool
