Warning: Your laptop must be connected to a power source before the update can start.
Note: This update may take up to 45 minutes to complete.
Your Dell laptop may require a BIOS (Basic Input/Output System) update to resolve issues that could impact its performance. The BIOS is the first software that runs when you turn on your laptop. It checks whether essential hardware components - such as the keyboard, memory, and hard drive - are functioning properly. Then, it locates and loads the operating system, allowing your laptop to start up. Without the BIOS, your laptop wouldn’t be able to boot or operate.
A known issue has been identified in certain Dell laptop models (Latitude 5450 and Latitude 5550's) that may cause them to become non-functional if a BIOS update is not performed.
