Environment:

CofC-owned computer

Cause:

Lack of power source

Resolution:

Troubleshooting

  1. Is the computer plugged in?

  2. Is the power outlet the computer is plugged into working? If you plug something else into the same outlet, does it work? If the problem is with the power outlet, contact Facilities Management.

  3. If the computer is plugged into a surge protector or UPS instead of directly to a power outlet, is that device plugged in, powered on, and confirmed working? The switch on a surge protector can easily be switched off, especially if it is underfoot.

  4. Has there been a recent power outage? Try unplugging the computer. Leave it unplugged for about 20 seconds. Then plug it back in and try again.

  5. What color is the power light?

    • If it is flashing orange, this indicates a possible power supply failure in the computer (or some other issue to be resolved by field techs). Escalate to field technician using Computer Repair and Service form.
    • If it is flashing white (or blue) and won't power on after you press the power button, try a hard shut down. Press and hold the power button until it completely shuts down. When you are sure it is shut down, press the power button to power it on.

    • If there is no light at all, turn the computer on by pressing the power button. If it still won't power on when you press the power button, this indicates a possible issue with the power source it is plugged into (like the wall outlet, for example). Revisit steps 1-3 above. 

  6. Check the power button on the monitor as well. What color is the light for the monitor?

    1. No light from the monitor's power button:

      • Make sure the monitor is plugged in. There should be two cables coming from the monitor - one for power and one for data. Make sure that both are securely plugged in. 

      • Press the power button to turn it on.

    2. Orange - the monitor is on, but there is no image or the image 

      • Confirm the data cable is securely plugged into the monitor as well as the back of the computer

      • Confirm the computer is powered on

      • Escalate to field tech if still not resolved

  7. Laptops

    1. Is the battery charged?

    2. Try another power adapter.

    3. Try another power outlet.

    4. If it is on a docking station, reseat the laptop on the docking station.
