When you bring your computer to us, we take the time to fully understand the problems you are facing. If your computer issues require us to investigate the problem (e.g. this thing intermittently makes this sound), we’ll check your device in and charge a small diagnostic fee. Once we’ve determined the problem, we’ll follow up with you with next steps and any further costs associated with the repair. Sometimes problems are resolved during the diagnostic process, and no additional costs would be incurred.
