My MBP just started to flicker badly irrespective of the GPU, so I reserved a genius bar appt. for tomorrow. I don't know whether the issue is related to the logic board or power inverter; based on the numerous blogs and threads that I have read, it could be one or both parts. However my question is instead of leaving my computer at the Apple Store for a short period of time(5-7 business days), can the Apple Store order the parts that they need for repair and call me when they arrive and install that day, so I have this machine with me at all times? Normally, I wouldn't complain, but I have major FCP/ CS4 work that I need my faster pro for. Any and all help is greatly appreciated. Saki.
