Surface Go 2 UEFI Photo

By Evan Forrest (SurfaceTip)

Since the first generation of Microsoft Surface Pro (2013) and Surface 3, Microsoft has implemented custom BIOS firmware on those devices to support required hardware features and securities.

Starting with Surface Pro 4, Microsoft has created its own UEFI firmware for use with newer devices. This new firmware is called Surface UEFI, which is currently used on newer devices, including Surface Go, Surface Book, and Surface Studio.

Surface Go has a slightly new design interface compared to other Surface models, including a different on-screen keyboard. This article will walk you through how to access and configure the Surface Go UEFI settings.

How do you access Surface Go UEFI settings?

You can only enter the Surface Go UEFI setup screen while your Surface is starting. Here is how you do that:

  1. Shut down your Surface.
  2. Press and hold the Volume Up button on your Surface, then press and release the Power button.
  3. When you see the Surface logo screen appear, release the Volume Up button. The UEFI settings menu will appear in a few seconds.

After you have made any changes to the UEFI settings, you can save or delete those changes by:

Save changes and restart your Surface

By default, every change you make will automatically be saved. When you restart your Surface, all settings will take effect. To do so.

  • In the UEFI settings menu, select Exit.
  • Click Restart Now.
    Surface Go UEFI - Exit
  • It will save all the settings you have changed and restart your Surface.

Restart your Surface without saving your changes.

You also have the option to discard all changes as well by using your Surface Type Cover or external keyboard. To do so.

  • On the keyboard, press the ESC key.

  • Now you have two options:
    • Yes – Delete your changes and restart your Surface.
    • No – turn back to the UEFI settings.

How do you check your Surface Go device information via UEFI settings?

The PC information page is the first displayed page when you enter UEFI settings. You can find more information about your device identities on the page, such as Model, System UUID (Universally Unique Identifier), Serial Number, and Asset Tag. Moreover, it also displays all important system component versions you might need for troubleshooting.

  • Enter Surface UEFI settings as per the instructions above.
  • In the UEFI settings menu, select PC Information, and you will see the following information:Surface Go UEFI - PC Information

How do you manage device components on Surface Go UEFI Settings?

Surface Go allows you to deactivate some of your surface device components and features to meet your specific security requirements. You can turn those components on or off by:

  • Enter Surface UEFI settings as per the instructions above.
  • In the UEFI settings menu, select Security, and you will see the following options:
    Surface Go UEFI - Devices

    • Type Cover port – turn on/off the Surface Go type cover.

How do you change your Surface Go date and time via Surface UEFI?

The new Surface UEFI now allows you to set your Surface Go’s date and time on the UEFI settings page. To check or set a date and time for your Surface Go:

  1. Enter Surface UEFI settings as per the instructions above.
  2. In the Surface UEFI menu, go to the Date and Time page as below:Surface Go UEFI - Date and Time

  5. Press Enter to apply changes.

How do you protect UEFI settings with a password on Surface Go?

You can prevent others from changing your UEFI settings by setting an Administrator Password in UEFI settings. To do that:

  • Enter Surface UEFI settings as per the instructions above.
  • In the UEFI settings menu, select Security.
    Surface Go UEFI - Security
  • Under the UEFI password, click the [Clean] button to create a UEFI password.
    Surface Go UEFI - Entering UEFI Password
  • You will need to enter a password in the box with your keyboard or the on-screen keyboard with the following criteria:
    • Minimum Length: 6 characters
    • Maximum Length: 128 characters
    • It may contain a combination of letters, numbers, and special characters.
  • If you have set the password before and want to remove it, leave the password box blank.
Note If you enter the administrator password incorrectly three times, you’ll be locked out of the UEFI. Restart your Surface to enter the password again.

Important If you set a password for the UEFI, record it in a safe place. If you forget the password, you won’t be able to access the UEFI settings. You can only reset the administrator password from within the UEFI.

What is the Trusted Platform Module (TPM)?

The Trusted Platform Module (TPM) technology significantly advances BIOS in hardware-based security features. It is a specialized chip that stores RSA encryption keys specific to each Surface device for hardware authentication.

The TPM technology is a requirement of BitLocker disk encryption. The TPM helps you encrypt/decrypt the entire disk without requiring complex long passphrases. It means the encryption and decryption keys are stored within the TPM chip. So, your encrypted disks can’t be accessed on other devices.

What is Secure Boot Control?

The Secure Boot is a technology that blocks the loading of uncertified bootloaders and drives. It helps to prevent your Surface from being loaded with unauthorized operating systems and malicious software applications.

If you desire to install other operating systems like Ubuntu or other Linux distributions, you may need to turn off this feature in the UEFI settings above.
