First of all, hi! This is my first post here, yes I used the search and could not find this exact situation. I'm trying to convert back to windows from Mac and would love to get this out there. I bought my SP3 used from Swappa on the 6th. Loving it. Yesterday after I finished working on a website I closed the keyboard put in my bag and went home. When I wanted to watch youtube when I was home it would not power on. So even though I thought I had battery I charged it. After an hour I tapped the power button and the lock screen came up, I walked away without unlocking it and came right back and nothing. Keyboard would not light up, but the charging light on the cable lights up. I searched here and did allllll the button presses and almost the freezer. So after hours of troubleshooting I decided to just let it be. This morning still nothing, until an hour ago and it just came back on. So as I'm typing debating on sending this out of warranty device back I wanted to ask this. Here are some settings I turned on recently that may have affected this? 1. "Save me power when device knows I'm away" Could this be the culprit? Did it just not realize I wanted to use it? What is this anyway? 2. "Battery saver status until next charge" So now it's up and running I turned those off. I do have a few errors in the event log around the time and during all my attempts to turn on I have a bunch of Kernel-Processor-Power (Microsoft-Windows-Kernel-Processor-Power) Errors: The speed of processor 3 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report. ______________________________________________ Another one that goes on for ever 19 of them. Enumerating user sessions to generate filter pools failed. ______________________________________________ Installation of the Proof of Purchase from the ACPI table failed. Error code: 0xC004E016 ______________________________________________ [ Name] volmgr - EventID 46 ______________________________________________ [ Name] Microsoft-Windows-Kernel-Power [ Guid] EventID 41 ______________________________________________ There is a whole lot more but I don't know what a lot means so if I anyone can point me in a good direction I'd appreciate it. Thanks! And if this is in the wrong place I'm sorry, I'm just in a hurry and kinda freaking out since I bought it used.
