I am executing shudown.exe /s /t 0 from the desktop. Results are the same as if I use the Start Menu power button
I uninstalled the ACPI device and rebooted which causes it to be reinstalled. After this shutdown works OK. The next time shutdown does not work.
When it does not work the system shuts down, but the light on the power switch stays on. I have to hold down the power switch till it goes out before I can restart the system.
