The same error occurs in the bios updater of the blade 13 2019 version. I tried to update it on 10 and it works normally, but it cannot be updated normally on 11. I'm still having the same problem half a year later, they didn't adjust the updater... (My laptop had a new motherboard)

@Razer.Speedcr0ss ? :)

Same issue here running Win11 Pro with the late 2019 RBS.  Razer support provided help through Reditt but without success.  The updater opens, acknowledges Bios 1.02 updating to 1.05 but on reboot the update does not process.  I completed complete uninstall of Razer Synapse and still nothing after reinstall.   

HELP Razer….this needs a fix. 

They told me last year it would be fixed soon

(I submit a support case)

Hahaha

Last week Razer provided the following details on the specifics of the Bios updates 1.03 to 1.05:

 We'll indicate the changes below but there might be minor changes that are not listed.

• Fix no Razer Logo during boot up
• Fix system hang during reboot after setting “Core Isolation > Memory Integrity" to ‘ON’

That's all the info that we can provide as of this moment.

As the noted updates were not issues on my RBS and did not specifically address the throttling issue I read about, I chose to defer my efforts to resolve the bios update issue.  Furthermore,  HWMonitor indicates a max attained power of 25W so doubt the throttling is an issue either.

May be time for me to accept the fact it’s running fine without the updates and forget about them.  Not an easy task though, as my preference is to stay completely updated! 

@owenjamesevans do you have problem with screen flickering after waking up from sleep?
i have same laptop Razer blade 15” advanced 2019 (RZ09-0301x), and i have some issues screen flickering or blingking after waking up from sleep, and then i tried update bios 1.00 to 1.04 at windows 11hz22, and still got bios 1.00

so annoying

When I first bought the machine back in 2019 I had some screen drop outs but that hasn’t been a problem for a long time. 
I’ve always been on bios v1.02 though. Not 1.00. 
 

I got round the problem in the end by making a secondary partition and installing windows 10. Ran the updater within windows 10. Then deleted the partition once the upgrade competed. 
 

that way I didn’t have to nuke my files etc to go back to win 10.

I too have had the same problem. I had updated the BIOS from the same official page. once installed and restarted my "Razer Blade 15 2022" it stopped working. IT SIMPLY DOES NOT TURN ON AND THE SCREEN STAYS BLACK AND SOME KEYBOARDS LIGHT RED. RAZER TECHNICAL SUPPORT HAS NOT HELPED ME AND THEY JUST GOT ME A WALK. THEY HAVE NOT GIVEN ME ANY SOLUTION DESPITE HAVING THE CURRENT WARRANTY

IF SOMEONE HAS FOUND THE WAY TO SOLVE IT, PLEASE TELL ME WHAT YOU DID

If you’re on windows 11, disabling secure boot in my BIOS worked.

I have a 2019 Razer Blade stealth 13. I disabled secure boot and it finally worked. I also disabled Microsoft Driver Block List in the security settings before the bios change but that didn’t work at least not by itself anyways.
