I have product Razer blade 15 (2022) RZ09-0421EED3 had updated the bios from this link: https://mysupport.razer.com/app/answers/detail/a_id/9729

Once updated and restarted the laptop has stopped working and now it won't turn on. Only the red keyboard lights up.

The laptop worked 100% correctly before, after updating the bios it stopped working.
The laptop does not work both plugged in and not plugged in

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
