I just built a new Windows 8 PC, and started using it a few days ago. Every night, I use Hibernate on the computer before I go to bed. The only way to turn it back on is to hit the Power button.
Every night, the computer wakes up from Hibernation around 3 am. Here's the past four days, from when I first started using the computer:
- Started using the computer.
- Was using the computer at 3 am, so didn't notice any wake-from-sleep problems.
- Computer wakes from Hibernation at 2:59:43 am, according to the Event Viewer.
- Again, the computer wakes from Hibernation at exactly 2:59:43 am.
In the Event Viewer, there are a few relevant events, but none that really specifies the cause of the wake up. For instance:
The system has returned from a low power state. Sleep Time: 2013-07-17T02:46:44.930338600Z Wake Time: 2013-07-17T06:59:43.986364300Z Wake Source: Unknown
The following is possibly relevant?
The start type of the Background Intelligent Transfer Service service was changed from auto start to demand start.
And there isn't much else. I had changed the Power Options from the default "Balanced" to "High performance" early on. Could that be related somehow? Also, I've already followed all the steps outlined here, which includes
powercfg. I ran the following commands:
C:\Windows\system32>powercfg /lastwake Wake History Count - 1 Wake History  Wake Source Count - 0
C:\Windows\system32>powercfg -devicequery wake_armed NONE
C:\Windows\system32>powercfg -waketimers There are no active wake timers in the system.
Also, I have my keyboard and mouse plugged in to my PC via USB 3 ports rather than USB 2. I'll try switching them to USB 3 and seeing if that works.
I've also got an ASUS motherboard with an UEFI BIOS, so I checked the UEFI BIOS for "wake-on-LAN" via the Boot Priority, and I only had it set to 1. Hard Drive, and 2. DVD drive. LAN was not listed there, like it appears in the screenshots in the instructions that ASUS provides.
Does anyone have any other ideas? I feel like I've tried almost everything.
