Upgrade the Basic Input Output System (BIOS) for an Acer Aspire 5580 to troubleshoot hardware problems and certain operating system issues. Upgrading, or flashing, the BIOS allows your computer manufacturer to install an updated BIOS to address changing hardware and newer operating systems. Your BIOS software is required to start hardware during the boot process and to allow your hardware to work in sync with your operating system. After you obtain the BIOS upgrade file, the actual upgrade process is mainly automated, requiring little user interaction.

Press the “Browse” button.
Choose the BIOS upgrade file, with a “.wph” extension, within the downloaded folder located on your desktop.
Press the “Flash BIOS” button to begin upgrading the BIOS. Your Acer Aspire 5580 will restart after the process is finished.
If you have problems locating the file with the .wph extension, open any folder on your desktop. Select the “Tools” menu and choose “Folder Options.” Under the “View” tab, uncheck “Hide extensions for known file types.” Exit the options window and browse for the file again.
Only upgrade your BIOS if absolutely necessary. Use a BIOS upgrade as a last-resort troubleshooting method. Flashing the BIOS incorrectly or using the wrong upgrade file will result in system errors and possible BIOS corruption.
