Logitech keyboards will work during a computer's startup process when connected directly to the Logitech Unifying or Logi Bolt receiver.

This means that during POST (Power-On Self-Test), within the BIOS, using bootloaders and until the operating system has been fully loaded, you will be able to make use of our keyboards.

Here are some things you need to be aware of to ensure that your keyboard works during startup:

• Use your Logitech Unifying or Logi Bolt receiver on a USB 1.x or 2.x port, as some USB 3.x ports on certain motherboards can cause potential issues.
• Do not connect your Logitech Unifying or Logi Bolt receiver using a USB hub, dock, or other types of extenders, as these may prohibit the correct use of your keyboard.
• By default Logitech keyboards do not have the F-keys enabled. This means that during POST (Power-On Self-Test) if you want to access the BIOS, you need to press the FN+F-keys. The F-key would be the key normally assigned to access the BIOS on your computer, usually, this is F2 or F8.
  Warning: Accessing and adjusting your BIOS settings without proper knowledge can potentially cause issues resulting in your computer not starting or displaying other issues. If you are not familiar with how to adjust the BIOS settings, please contact your computer or motherboard manufacturer.
• If you’re using an older motherboard, please enable Legacy USB Support or USB Keyboard Support in the BIOS settings. You may need to connect a different, wired keyboard to access the BIOS to adjust these settings.
• If your keyboard does not work with your bootloader, such as GRUB, please consult the bootloader documentation to understand how to enable USB HID keyboard support. Most bootloaders will have this enabled by default, but some require manual configuration to enable it.
