Step 1: Turn Off Bitlocker Encryption
You must temporarily disable the BitLocker encryption on your Alienware laptops before you update the BIOS. BitLocker stores its encryption keys using the Trusted Platform Model (TPM), which is integrated into the laptop’s Motherboard.

windowsdefender:, and hit Enter. This will open the Windows security app.
- Go to Device Security.
- Under the Data encryption section, click on Manage BitLocker drive encryption.
- It will show you the drives on your computer with their encryption status.
- Select Turn off BitLocker and follow the onscreen prompt. This will disable the encryption on the selected drive.
