-------------------------------------------------------------------
Symptoms:
After system goes to sleep I am unable to wake it up by any means. Keyboard, mouse, POWER BUTTON, wake-on-lan, reset button, plugging in USB devices. The only way I can wake it back up is by removing the power cord for 3 seconds and then powering on the system from the power button. What is interesting is that when the system starts up the open windows from the previous session are restored as if it was successfully woken from sleep. I would say that it was a hibernation state but I have explicitly disabled hibernation as the following data will show.
Diagnostics:
-------------------------------------------
Power plan settings:
Power plan: balanced (sleep after 1 hour)
Require password on wakeup: yes
Allow hybrid sleep: on
Hibernate after: never

-------------------------------------

Turn on fast startup (unchecked)
Sleep (checked)
Hibernate (unchecked)

-------------------------------------------
With windows 7 the system could only intermittently enter sleep but had no issues waking from sleep
The system can power on normally from a complete shutdown and can wake-on-lan consistently but not from sleep state.
Bios settings:
Suspend mode: auto
[other options are S1 (POS) only and S3 only]
ACPI 2.0 support: enabled
ACPI APIC support: enabled
----------------------------------------
Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported true
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true
