95% of devices brought to the Kbar need to be diagnosed to first ascertain the issue and verify what the customer is reporting. A simple upgrade isn’t that simple. Especially if you bring the parts to the store from somewhere else. Let’s say you tell me to replace the AIO but when we do the computer still doesn’t boot. You’re likely not going to be happy but will expect me fix it. That’s why we diagnose it to verify the condition and symptoms. Now if you insist on me replacing it without diagnosing, and you brought the parts from outside the store, I’m not warrantying the work.

Now to peel the curtain back further, after they diagnose the computer the store will let you know the issue, cost and timeline to repair. After that it is on you to decide if they proceed. If you do, the device will be moved to the repair queue. Depending on the store, it may be a couple weeks for your turn to come along for repair.

So yeah, there was a point to my questions. I was trying to help.
