Hello, 

I have a Razer Blade Advance model from 2018 RZO0-0238xxx that won’t boot into Windows . Cannot access the BIOS menu either, no keys are working . Have tried deconnecting  everything and unplugging it and also the holding the power button and removing the plug trick. Nothing works. I’ve had the battery removed a few years ago since it bulked up and the RAM and SSD upgraded. Please help!
