Secure Boot is a UEFI-based security feature that ensures only trusted software runs during a device's startup. It relies on digital certificates stored in firmware to verify pre-boot components like boot loaders and firmware drivers. It defines trusted code through a firmware policy set during manufacturing. Changes to this policy, such as adding or revoking certificates, are controlled by a hierarchy of keys. This hierarchy starts with the Acer PK (Platform Key), the Microsoft KEK (Key Enrollment Key, also known as Key Exchange Key) and Acer KEK. The Allowed Signature Database (DB) and the Disallowed Signature Database (DBX) determine which code can run in the UEFI environment before the OS starts. The DB includes certificates managed by Acer and Microsoft, while the DBX is updated by Microsoft with the latest revocations.
Acer and Microsoft originally issued Secure Boot certificates in 2011, but these are set to expire starting June 2026. To maintain Secure Boot functionality and continue receiving security updates, devices must update to the new 2023 certificates.
How to Update Your Secure Boot Certificates
Updated Secure Boot Certificates are incorporated into the latest BIOS update for your product. You can download the latest BIOS update for your model from the Acer support website.
- Open your web browser and go to http://www.acer.com/support.
- Enter your Serial Number or select your model from the list.
- Select BIOS/Firmware.
- Locate the latest BIOS for your system and click the Download link on the right side.
- Open the folder where the file downloaded to, then right-click on the file name and select Extract All.
- Double-click the file application file that was extracted to begin the install.
- Follow the instructions on the screen to install the BIOS. Make sure you have an AC adapter connected.

Frequently Asked Questions
Q: How to identify the manufacturer date code of the unit?
A: The manufacturer date code is listed on the serial number label on the computer as shown in the image below.
Q: What should I do if my device doesn’t start or enters BitLocker recovery after installing the new Secure Boot certificates?
A: Acer recommends backing up your BitLocker Recovery Key before updating the BIOS with new certificates. You can save the key to your Microsoft account or a USB drive.
If your device enters BitLocker recovery mode after restarting:
- On the BitLocker recovery screen, enter your 48-digit BitLocker Recovery Key (hyphens are optional).
- Once entered correctly, your device will start normally into Windows.
For more information, see the following resources from Microsoft:https://support.microsoft.com/en-us/windows/find-your-bitlocker-recovery-key-6b71ad27-0b89-ea08-f143-056f5ab347d6
