How To Update BIOS On Alienware Laptop

When you update the BIOS of your Laptop, you may receive added hardware support, security updates, and stability enhancements. However, if you are not careful enough while performing the updates, it can give diminishing returns.

For Alienware laptops, Dell offers a convenient update package that can update your BIOS without many risk factors involved. There is also an option for these laptops where you can install the updates without having to Boot into the operating system. 

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. 

Because of this when you update the BIOS, the system will not accept the BitLocker Keys and you won’t be able to boot into Windows after the BIOS update. 

Note: BitLocker encryption is not available in Windows 10 and 11 Home. This step is only applicable to users with the Pro, Enterprise, and Education editions of Windows.

  1. Press Windows Key + R, type windowsdefender:, and hit Enter. This will open the Windows security app.
  2. Go to Device Security.

  4. It will show you the drives on your computer with their encryption status.
  5. Select Turn off BitLocker and follow the onscreen prompt.  This will disable the encryption on the selected drive.

  6. You will need to turn off the Bitlocker on every drive. 

Step 2: Check the Current BIOS Version 

After you have suspended the BitLocker, check the currently installed BIOS version. System Information can give you crucial information regarding the BIOS version, manufacturer, etc. 

  1. Press Windows Key + R, type msinfo32, and hit Enter. This will open the System Information Window.
  2. Under System Summary, check the BIOS Version/Date field. You will find the information on the current BIOS version here. You will need it to download the newly released BIOS update.

  6. Click on the Download button. The installer will now start downloading. 

Note: If the existing version of BIOS on your Alienware is two versions behind the latest released update, it is advised that you update the BIOS gradually without skipping the prior versions. This is to avoid compatibility issues during the BIOS update. 

Step 4: Installing the BIOS Update

Once you have downloaded the installer from Dell’s website, it’s time to perform the BIOS update. But before you proceed, follow these measures for a successful BIOS update.

  • Keep the Laptop’s charger connected the whole time during the update. 
  • Close any program that could interact with the update process.
  • Make sure the update process does not get halted at any point as this can make your computer not function.
  • Each time you wish to update the BIOS, suspend the BitLocker Encryption and gradually perform the update without skipping any versions.

After you have ensured these precautionary measures, this is how you update the BIOS on your Alienware device. 

  1. Go to the download directory and run the BIOS update’s executable file.

How to Update Alienware’s BIOS Using USB?

There’s another way that lets you flash the BIOS, in case you cannot access the Operating system. You can create a Bootable USB flash drive with a BIOS update package and perform the updates. This comes in handy for a new system on which Windows is not installed or is corrupted. 

You need to rely on another computer to make your USB drive bootable i.e for steps 1 and 2.

Step 1: Install DDDP

In order to create a bootable USB flash drive with a BIOS update file, you need to use the Dell Diagnostic Deployment Package (DDDP) software. 

  1. Download the DDDP package from Dell’s download page.
  2. Go to the download directory and run the software package.
