Hello kc1995, if the battery in the touchscreen needs to be replaced, we would need to have a technician to do that. If it's all other devices, you can do that yourself. I can look into this for you from here, can you verify your account information with me? I would need your phone number, full name, and service address. You can private message me by clicking my name and clicking private message.
The link below is the only place that I could find for removing the touchscreen battery. It talks about removing it for shipping. I would think that you could then pop in a new battery (what kind does it take????) and not have to have a technician do it!
