What is BIOS and why does it matter?

BIOS (Basic Input/Output System) is the firmware that helps your laptop start up and connects the hardware to the operating system. Keeping your BIOS up to date can fix bugs, add support for new hardware, and improve system stability. If you’re seeing issues like random restarts, hardware not being recognized, or error messages, a BIOS update may help. So it’s worth checking if an update is available whenever your device isn’t acting as expected.

What to do before updating your BIOS

Before you jump in, it’s important to prep your system so everything goes smoothly. Taking a few minutes now can help you avoid problems later.

1. Back up your important files—just in case.
2. Plug in your laptop so it doesn’t lose power during the update.
3. Before you update, restart your laptop and press F2 or Delete when the Dell logo appears to open the BIOS menu. Most people won’t need to change anything, but if you’ve ever customized settings—like boot order or security options—write those down or take a photo. This way, you can double-check or restore them after the update if needed.

Once you’re ready, you can start the update process.
