How to Flash BIOS on an Aspire 7520

Keep your Basic Input Output System up to date on an Aspire 7520 to solve and prevent certain hardware and operating system issues. The update process is called "flashing" the BIOS. During the flash, a new version of your BIOS is installed on your Aspire 7520. As problems are discovered, Acer releases free BIOS updates. Though BIOS updates are not required, flashing the BIOS is recommended after upgrading your operating system and certain hardware such as a hard drive, memory or video adaptor.
