Updating the BIOS via Windows or DOS
Usually a BIOS update program includes installation instructions. For Dell, HP laptops, etc. It’s just an install exe file that can be run like any of their driver files, and takes care of the rest.
The update installation file is usually placed in a ZIP archive along with instructions. Remove it and read the instructions carefully. While updating, turn off all unnecessary programs and plug your laptop or computer into a reliable power source. A power failure or surge will cause your computer to stop working.
