I went to charge my 2016 15" MBP via Apple power adapter and heard two beeps. I thought that was odd. I checked back an hour later and my battery was still at 15%. Took it into the Genius Bar, reset PRAM and SMC, then they confirmed that all 4 USB-C ports were completely dead. I've only ever used Apple branded USB-C adapters during the last 3 months that I've owned this laptop. The repair estimate was $575 to replace the logic board. Fortunately its still under warranty, so no charge to me. I'll lose all of my data since the SSD is soldered to the logic board. No chance of backing up now that the battery is down to 3% after all of the diagnostics. I bought this machine despite the negative reviews because I've always owned Mac laptops and I like the hardware. This is a very disappointing turn of events for this product. Was already on the fence about the future of Macs. This is not helping.
