Question Cannot Access BIOS After Update Lenovo Ideapad L350-15API

Sep 27, 2020
I bought a new Lenovo Ideapad L340-15API the Ryzen 7 3700u variant and upgraded the RAM to 12 GB and added a 480 GB NVMe SSD.

I updated the BIOS of the system to the latest version ARCN34WW.

Now I cannot enter the BIOS or the BOOT menu no matter what I try, the "NOVO" button, the "DEL" key, 'F12", "F2", reboot from the OS.
It just gives me a black screen and that's it, the system fan ramps up but to no result.
I tried to drain the battery to no success.

I have a dual boot system with Windows 10 1909 and Elementary OS Hera

What can I do to solve this ?
Please notice that everything is working correctly, when I boot I get the GRUB OSes selection menu, the system sleeps and hibernates correctly.
I just cannot get into the BIOS
I tried Lenovo community forums, I found several variant problems with this BIOS update and non had a fix.
