How do I know if my Chromebook is ready to work for lab? Chromebooks use Chrome OS which is frequently updated by Google. When getting ready for lab, it is always a good idea to let the Chromebooks be turned on and allow them to communicate with the network. This will allow the Chromebook to complete any background tasks that could have become available while the Chromebook was shut down. As a rule, the longer the Chromebook has not been used, the longer the time that should be allocated to allow the Chromebook to update on start. Using the Task Manager, you can check to see if the Chromebook resources are tied up with a background task. To get the best performance from SPARKvue, it is best to minimize the background tasks that are working with using SPARKvue.
