Resume from Sleep / Hibernate issues

Question

Hi all,
First time poster. I have a Helix and am running into a heap of resume from sleep (and hibernate) issues.
The sleep issues tend to happen overnight - I do not have this issue if I sleep the machine and then wake it up 5-10 minutes later (e.g. moving between meetings at work). However, when I attempt to wake the machine up in the morning, it fails to resume from sleep, and instead boots from scratch.
Typically, when the unit is in this state, the status led on the lid is rapidly blinking (which I believe means that it's trying to enter sleep) Since there is nothing in the Windows event log during the overnight period, I'm wondering whether it's trying to enter a deeper sleep mode and failing.
This happens every second day or so. Which is really frustrating as a tend to lose some work.
I tried enabling hibernate as a trial, to see if that would avoid the issue, but resuming from hibernate fails as well. At least I get a Windows event log entry for this (source: kernel-power. The unit fails to resume from hibernate with status 0xC000000D)
I have the September 10 BIOS update, and am running Windows 8.1 Enterprise (though I had the issue with Windows 8 as well).
Any ideas on how I can troubleshoot this?
Regards
AC

Answer 1

Windows 8: In Windows 8, the default shutdown behavior puts the system into hybrid shutdown (S4) and all devices are put into D3. Remote wake from hybrid shutdown (S4) or classic shutdown (S5) is completely unsupported. In Windows 8, NICs are explicitly not armed for wake in both the classic shutdown (S5) and hybrid shutdown (S4) cases because users expect zero power consumption and battery drain in the shutdown state. This behavior removes the possibility of spurious wakes when explicit shutdown was requested. As a result, Wake-On-LAN is only ever supported from sleep (S3) or hibernate (S4) in Windows 8.
Note that in Windows 8, hybrid shutdown (S4) stops user sessions but the contents of kernel sessions are written to hard disk. This enables faster boot.

From the Helix User Guide:
•Slow blinking: The tablet is in sleep mode.
•Fast blinking: The tablet is entering hibernation mode or sleep mode.
That was my reason for clarifying if hybrid-sleep was enabled; since it's the default setting and you noted that the LED was blinking fast. Does the LED ever stop blinking fast?
There can/may be multiple log entries during a normal sleep operation,  because "the system uses the lowest-powered sleep state supported by all enabled wake-up devices." If one of those devices wakes the system (this does not mean power on) then the logs will report the devices and will likely return to a another level of sleep, but this does not mean full power loss or empty logs.
If the system has successfully entered sleep state, then you should see the following message in System Event logs. 
Event 42, Kernel - Power
This system is entering sleep.
Sleep Reason: Button or lid
When the system is successfully woke you will see a System Event Log similar to this:
Event 1, Power - Troubleshooter
The system has returned from a low power state.
Sleep time: 2013-10-08T01:42:25.XXXXXXXX
Wake time: 2013-10-08T05:53:21.XXXXXXXX
However, there will be other events in the logs after sleep and prior to this wake period, such as hardware device issues(My helix has Bluetooth device warnings, nfc driver warnings and some other nondescript hardware errors), kernel messages (about boot manager, boot options, etc.).
Have you changed the behavior of the power button?
You also can program the power buttons so that by pressing the power button you can shutdown the tablet or put it into sleep or hibernation mode. To achieve this, you need to change your power plan settings. To access power plan settings, do the following:
From the desktop, tap the battery status icon in the Windows notification area.
Tap More power options.
In the navigation panel, tap Choose what the power buttons do
Follow the onscreen instructions to configure settings.
Lastly, when you updated to Windows 8.1, did you format the whole C:\ (mSATA) drive?
