One of the most crucial things you can do before any service call is to backup your data. That way you're assured that whatever modifications are performed on your equipment, you have a stable backup of your data in the event any problems arise. For one reason or another, this may not be possible, or backing up your data is why you're seeking support in the first place. No worries, we'll discuss backup options when we arrive on site.
Another important thing to do is to gather up all your relevant passwords. WiFi networks, email accounts and device passwords are often necessary to perform routine service on various aspects of your equipment. Please have them ready in the event they prove necessary during your appointment. In the event you don't have your passwords, we'll do our best to help you retrieve them as needed.
