A user has noticed that the hard drive LED on the front of the computer has stopped working. However, the computer seems to be functioning normally. What is the most likely cause of the problem?

• The hard drive data cable is malfunctioning.
• The motherboard BIOS needs to be updated.
• The hard drive LED cable has come loose from the motherboard.
• The power supply is not providing enough voltage to the motherboard.
  

  Explanation: Each light on the front of the case is powered by the motherboard through a cable that attaches somewhere on the board. If this cable comes loose, a particular light on the front of the case will not work.
