Hello, you're experiencing some unusual keyboard behavior. It seems the system is displaying a code "B4" on your motherboard, which might be related to a USB hot plug. You also notice that your keyboard lights flicker or dim intermittently, sometimes covering most of the keys. When you restart, it briefly shows "B4" before booting normally. This pattern could indicate a power or communication issue. To resolve this, try disconnecting and reconnecting your keyboard, checking for any loose connections, and ensuring it’s properly seated. If the problem persists, consider testing with a different USB port or checking for any recent hardware changes.
