I have the Razer Blade RZ09-03305E53 for 4-5 years and recently I have been receiving this message "Invalid signature detected. Check Secure Boot Policy in Setup", according to the website below:

https://mysupport.razer.com/app/answers/detail/a_id/20795/~/how-to-fix-the-secure-boot-violation-message-on-the-razer-blade

It says its a CMOS battery issue. I have replaced the CMOS battery with the right model however the same message still appears when I turn on my laptop and enable security boot. How can I resolve this issue

Hey there, ​@MintGreencampquick399 

I understand that your Razer Blade displays the "Invalid signature detected. Check Secure Boot Policy in Setup" error whenever Secure Boot is enabled, and that the issue persists even after replacing the CMOS battery. 

Please send me a PM along with the following details below so I can create a case for you. Thank you!
