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.
Note: All Acer laptops and desktops manufactured after October 2025 have been updated with the corresponding new certificate versions.

The following Acer laptops and desktops have received BIOS updates that include the updated UEFI Secure Boot Platform Key (PK), Key Exchange Keys (KEK), and Allowed Signature Database (DB) with the new 2023 certificate versions.

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.
