Here the problem is that, the keyboard is not functioning properly. Here the booting is properly done. This problem points towards “BIOS” because, it is the responsibility of the “BIOS” to check for “input and output devices”. If there is any issue with it, it is the duty of BIOS to inform to the browser during the process of Booting.
So now the user has to troubleshoot the BIOS or call a system administrator to fix the issue. Even here, power supply might not be received by the keyboard.
