Can't boot into BIOS after taking my pc to a repair shop. (Please answer in polish language)

[ayqxiv]

Motherboard model: TUF B450-PLUS GAMING

BIOS Version: 4202.

My pc broke and I went to a repair shop with it. They also updated BIOS. When it was still working, I could boot into BIOS but after it broke and it came back from the repair shop, I couldn't go into BIOS.

Hello, @ayqxiv 

I am sorry for not being familiar with polish language.
May I inquire about the reason for sending it for repair (such as an inability to boot), and is the location where you sent it for repair the ASUS official service center? Could you please provide the RMA number?
Additionally, are there any other abnormalities besides the inability to access the BIOS at the moment?

Please try accessing the BIOS following the steps outlined in "How to enter the BIOS configuration" and confirming in the [Boot] page if the Fast Boot option is set to [Disabled].
Alternatively, you can attempt to restart the system after clearing CMOS and try entering the BIOS by pressing <Delete> or <F2>.

Thank you.
