Не работает клавиатура и мышка при вводе пароля в биосе Asrock

Даниил Козак 20

So, in the BIOS settings for playing faceit in CS-2, I turned off the TPM 2.0 mode, DMA detection, and Secure boot, and after rebooting, my keyboard and mouse suddenly stopped working. I have a password set on the BIOS, so I need to enter it after turning on the PC, but I can't because my devices aren't working.

I've tried plugging my keyboard into different ports, both 2.0 and 3.0, but it hasn't worked.

PLEASE HELP ME!!!

Keyboard - red square keyrox tkl

Motherboard - Asrock b450 pro

Case - Cougar 330X

I've already scrolled through a billion forums, but nothing has worked

Hi Даниил Козак.

Thanks for posting here in Microsoft Community, I understand that after disabling TPM 2.0, DMA detection, and Secure Boot in the BIOS, your keyboard and mouse stopped working, preventing you from entering your BIOS password.

This is a known ASRock B450 behavior by disabling TPM and Secure Boot and DMA protection, the BIOS can break USB initialization before POST so USB keyboards aren’t detected early enough to enter the BIOS password but clearing the CMOS (either via the CLRMOS jumper or by removing the CR2032 battery with the PC fully powered off and unplugged) will reset the BIOS and remove the password also restore USB support and bring the system back to safe default settings where the keyboard works again.

May I know if your keyboard and mouse work at all during startup (for example, can you enter the BIOS), or do they only stop working after the BIOS changes were applied?

Best regards,

April P.

The keyboard and mouse don't even light up for a second when I turn on the PC. I can't even access the BIOS itself, because the very first screen after powering on is the password entry screen.

Thank you for an update, Daniil Kozak**.** since the keyboard and mouse never light up at power‑on, USB is not being initialized at the firmware level, so you cannot access the BIOS or enter the BIOS password at all, leaving a CMOS reset (or a PS/2 keyboard) as the only way to restore USB functionality and regain access.
