Basic Troubleshooting Steps in the Classroom


There may be occasions when technology devices fail or even when software programs do not do what they are supposed to. We know that this is especially frustrating when it happens in the classroom right before a lesson is delivered. This is why we have prepared a simple guide for troubleshooting basic issues that are also the most common. If you encounter any issues and if you are able to, please perform the basic troubleshooting steps below before contacting IT for assistance.


Check the cables – computers use several cables- please ensure they are all connected

Internet patch cable



Power cable

Video cable (Blue VGA or HDMI)

           Restart the computer – Leaving a computer on for days without rebooting or shutting down can cause it to become slower and can also reduce the life of the device. We recommend shutting down your pc each time you leave for the day and reboot it if you see errors.

Use process of elimination- If you're having an issue with your computer, you may be able to find out what's wrong using the process of elimination. This means you'll make a list of things that could be causing the problem and then test them out one by one to eliminate them. Once you've identified the source of your computer issue, it will be easier to find a solution.

For example: if a device does not turn on, the first thing to check is if it is connected to the power outlet. If your computer is powered on but nothing comes out on the screen/projector, then simply check if the video device is powered and turned on. Should this not fix the issue you may proceed to check the video cables and so on.
