Last night I have absolutely worst experience in my IT life... Just finished working on 4K video on my iMac 27" 5K Retina (late 2015), and go check out some videos on YouTube. Outside was some light rain. When is thunderstorm near my place, I allway, but really allways disconnect all my equipment from electric power. So, like in some bad movie, suddenly lightning strike in my house out of nowhere. I have UPS and two surge protected extension cord. In moment of impact, everything was power on; iMac, external Dell monitor, three external disks, printer, DSL router, TV, satelite, home theatre... Only iMac immediately was power of with some short sound as if something snapped inside. I was shocked, everything else was fine, no interrupt, no problems... So, I tried power up iMac, no lucky. Strange, if I connect exkternal disk via USB, there is power on disk whn iMac is powered. I tried SMC reset, another power cord, another socket, nothing... iMac is under warranty, tommorow I will contact local service and try to send iMac to them. I can't believe that only iMac was stricken. After that only one thunder lightning all night was quiet and calm. Horrible nightmare. Guys, if there any chance that Apple repair my iMac under warranty? And do you have any idea what is damaged? Thanks in advance. Best regards.
