Product: HP ProBook 445 G7 Notebook PC

Hi

I have an HP ProBook 445 G7 (AMD R5-4500U) laptop that did not update the bios, I always uploaded the latest version after a new version was released, the version on which my laptop worked was 01.16.00 Rev.A 02/2024, so I uploaded 01.17. 00 Rev. A 05/2024. Flash BIOS has three sequences, the process restarts three times, the first part was done, then I only had a black screen. I can turn on the laptop, the fan blows, it spins, I tried to connect the laptop to an external monitor, but without success, nothing appears on the screen. After removing the RAM 2x8GB DDR 4, the notebook for example beeps loudly, you can hear the speaker, so I assume that the motherboard is alive, it detects that it has no RAM.
I also tried the procedure with a USB flash drive with bios loaded. Through the WIN+B keys, but the recovery bios does not appear on the screen.
I also tried clear CMOS, disconnecting the cmos battery and the main battery.

Please, do you have experience with this? Maybe I didn't do a step somewhere, or I forgot something.
