Keyboards
If your machine, when booting, gives off a constant beeping noise, it is telling you that your keyboard is not connected or not working. Check the plug to make sure it's connected securely. Try unplugging it and re plugging it again.
If there is no response, check the indicator light on the keyboard. Is it on? Do the lights respond when you press the caps lock or the num lock key? If not, maybe your keyboard is broken.
Is there a key stuck? Gently pry off the cover and clean it with alcohol. Make sure it is not connected to your machine when you are cleaning it. The space bar frequently comes off track. Gently pry it off, noting which way the bar lies in your particular keyboard so you can replace it properly.
