Spectre 360 i7. Bought this 11/2017 and it failed two months ago. After latest update, I noticed my battery was dead every time I opened it up. At first thought it sat for too long but I charged it, closed lid and next morning it was dead. Plugged it in and it started up tar fine then I realized it would not turn off using shutdown menu, had to hold power button till it shutdown. I found out that was a mistake because now when power button is pushed, the led lights on button but screen stays black.
