So I'm fairly certain my MacBook is dead, but I want to see if anyone had any ideas before I take it in. I will start by saying I have a fair amount of technical skill. I've been a Mac owner for about 6 years, and I have worked with them extensively in my IT career for roughly 12 years. So I think I know what I'm doing for the most part. The MacBook (2016 m5 512GB) was purchased in August of 2016. I had the logic board replaced under warranty in May of 2017 when I started getting kernel panics that ended up being a faulty SSD. It has worked 100% rock solid for the last year. I updated it to High Sierra a couple days after release, and that didn't cause any issues. And for the record, this machine has been babied its entire life. It has endured no liquid damage or anything similar. I don't take it anywhere without placing it in at least a sleeve, and often a sleeve inside my briefcase. It has never been dropped or abused in the slightest. This morning I was using the computer off and on at work. The battery was at roughly 40% when I shut the lid at about 11:00 am. Then, at about 2:45 pm, I went to open the machine and saw nothing but a black screen. I clicked the trackpad and hit the space bar a couple times, but nothing came up. I could tell that the back-light was on, but the screen was all black. After a couple minutes I powered it down by holding the power button, pushed the power button again, heard the chime, and waited. The screen was black with back-light again, and after a bit the flashing question mark folder appeared. I did the usual SMC/PRAM/NVRAM resets. I plugged it in and tried it once more and got the same results. I decided to try recovery mode to see if I needed to repair the disk or one of its partitions. After booting while holding Command+R the machine defaulted to internet recovery. Uh oh. After about 30 seconds the globe quit spinning. I waited another 15 minutes and there was no indication of progress. So I powered it down and tried again, but now the machine is totally unresponsive. No chime, no backlight coming on; the only way I know it has power is that the force trackpad will do its "click" with feedback and sound. I've done a bit of searching over the last 30 minutes and haven't found anything of much substance. I'm 99% sure it's a logic board issue. Any ideas?
