Hi. I’ve got similar issues with my Blade 14 (2022) as reported in this thread: Razer Blade 14 (2022) RZ09-0427 Won't Boot.
The Laptop has been sitting on my desk a couple of days, charger was plugged, however, I disconnected the power for the last two days. Now the laptob doesn’t start. LED at the charger is constantly green. LED at the laptop initially flashed green (more like a fade-in-fade-out flashing). After trying troubleshooting described here https://mysupport.razer.com/app/answers/detail/a_id/1798/~/razer-blade-does-not-have-power%2C-wont-boot-up-or-turn-on the screen comes to live - but only black - and flickers in a constant frequency.
Unfortunately neither of the links provided in the above mentioned (and now closed) thread work for me (or I’m just dumb). Please help.
