Hello,
I have a Razer Blade 15 Base Model (Early 2020, RZ09-0328) running BIOS version 1.04.
I am experiencing a recurring Secure Boot issue.
Symptoms:
- After a complete shutdown and power on, Secure Boot is automatically enabled again.
- The system displays:
"Secure Boot Violation - Invalid signature detected. Check Secure Boot Policy in Setup."
- If I enter BIOS and disable Secure Boot, Windows boots normally.
- Restarting Windows usually works fine.
- The problem returns after a full shutdown.
Additional observation:
- The BIOS date sometimes resets to 01/01/2020 after startup.
- This makes me suspect a BIOS, RTC, or firmware-related issue rather than a Windows issue.
What I have already tried:
- Disabling and re-enabling Secure Boot
- Saving BIOS settings and rebooting
- Restoring Secure Boot settings
- Confirming Windows boots correctly when Secure Boot is disabled
Device Information:
- Model: Razer Blade 15 Base (Early 2020)
- Model Number: RZ09-0328
- BIOS Version: 1.04
Is there a known BIOS or firmware issue that could cause Secure Boot to re-enable itself after shutdown? Are there any BIOS updates or recommended fixes for this model?
Thank you.
