hp probook 4510s

black screen functional power supply

Hello I have a problem with my laptop HP probook 4510s. After switching on the notebook, all the necessary indicators light up, the fan feels everything works as it should, there is no warning beeping, only that the screen stays black. I have tried everything from pressing win+b, win+c, hard reset, CMOS reset, I also removed the RAM and CMOS battery. Nothing helps. I wanted to flash the BIOS, but I don't remember what WINDOWS I have installed and so I don't know which BIOS to download or how to flash and boot it correctly.
