My two weeks Dell XPS 9360 is having shutdown problem after windows 10 anniversary upgrade (ver 1607, OS build 14393.447). Spec is the highest in the Kaby Lake release.
I've just updated all the latest driver (installed Dec 1st 2016) from Dell website.
Now when i shutdown, the white light on the power button won't disappear like it used to, a.k.a. won't do a full shutdown. i have to do the uncheck fast boot options from power setting, but my startup takes twice longer (can take up to 25-30 sec), whilst previously only 15 sec max.
I prefer to have a fast startup and no shutdown problem like it used to. Unfortunately no roll back options for most of the drivers for some reason.
I've search and try every possible options listed in the forum and internet for this:
1. Removing Intel Rapid Storage
2. Downgrading to Intel Management Interface (IME) 9.5.24.1790, ver. 10, etc.
3. Tried every power management configuration for drivers, power setting, etc.
4. Tried every possible BIOS combination on fast startup, USB setting, Intel Virtualization
5. Diagnose hardware, driver, tried windows control panel troubleshooting, all shows normal
Basically i'm down to my last option of doing a clean install, but by doing this i'm loosing many settings which i don't intend to loose. And there's a chance that the problem persist even with clean install
The closest solution is disabling IME and uncheck the "allow the computer to turn off this device to save power" in the IME's power management. It helps for a minute making the full shotdown, but when i turn on the laptop for 5 minutes longer then the problem reappear.
is there any other option that i haven't think off? Or can i do clean install with guarantee that the problems disappear and i get my fastboot and proper shutdown back?
Thanks
