Some time user faces an error like ‘Keyboard not found. Press F1 to RESUME’ on their computers. It seems very funny but it exists in the BIOS based computers. Your windows 7 may also include this.
Basically this error message that you receive before Windows starts to boot are BIOS error, it’s a hardware related problem.
If you are facing this problem, you can try the following:
1. Check your keyboard connectivity with your computer.
2. Try plug-in another keyboard and check is it working? may be there is some problem in your keyboard.
3. Start the BIOS system. Check that if there is an option to turn off the notification of error on keyboard.
