There are two easy ways to check the bios version on your Dell laptop.
- During Boot: When your laptop boots up the bios version will splash on the screen. A current version of your bios will be something similar to A06.
- CPU-Z: Download and run CPU-Z here. Once you download and run this application click on the Mainboard tab which has a BIOS section.
Once you know the bios version you can check Dell’s web site to see if a newer version is available. If a new version is available installing it can resolve possible bugs with your computer.
