It’s important to only update your BIOS (also known as “flashing” your BIOS) when there’s a good reason. You should only consider updating if you’re experiencing a specific issue, like new hardware not working properly and a BIOS update is the recommended solution. If everything is working fine, or unless Dell specifically recommends it, it’s best to leave your BIOS as is.
1. Via the Windows Operating System
To update the BIOS on your Dell computer or laptop, you first need to find out which version your system is currently using.
2. Use a Bootable Flash Drive
If you can’t log into your system but need to update its BIOS, you can do it by booting from a USB flash drive. First, make sure the USB is set as the first boot option in your BIOS settings. To check your current BIOS version, turn on the system and keep pressing F2 until you see the BIOS setup screen. The BIOS version will appear next to ‘BIOS Revision’.
