Updating your bios, also called system setup is an essential part of not only improving computer performance, but it also provides more security and increases stability of your PC.
Before updating bios, you will need to temporarily suspend bitlocker. If you use Bitlocker for encryption in the taskbar, use the Windows Start button to access settings.
Click on the Privacy and Security Option. Then on device encryption. Next, click on Bitlocker Drive Encryption and in the new window. Click on Turn Off Bitlocker.
Confirm the action by clicking on the Turn Off Bitlocker button to turn it back on again. Just repeat these steps. Now is the time to ensure your laptop is connected to the charger.

This will help prevent possible compatibility issues. Select each of the versions pending to download and run them from the computer one by one. Going in order from the oldest to the newest.
Each installation should be done individually. Keep in mind that the system will restart each time as part of the process. A system restart is necessary to complete the BIOS update, so be sure to save any work beforehand.
