    8 There is a known problem with almost all utilities that power off your system.  This is not a defect in ACPI.PSD or related software.
     8There is a known problem with almost all utilities that power off your system, including the xworkplace eComStation extended shutdown.
     9
     10The problem occurs when these utilities shut down the file systems before the power off routine has been paged into memory. When the utility calls the routine to power off the system, the kernel can't page it into memory because the file systems have been stopped.  This is not a defect in ACPI.PSD or related software and cannot be fixed in the any of the ACPI software.  It must be fixed in the power off utility.
     11
     12Because of the nature of this defect, power off utilities with the defect may have randomly worked in the past because the power off routine may or may not have been in memory for some other reason. If things move around in memory, or some other program causes the routine to get paged in, the power off may have worked.  The only way to reliably fix the defect is to fix the power off utility.
     13
     14You can test the power off functionality by opening a command window and typing the following command:
     15{{{
     16acpistat poweroff
     17}}}
     18This command properly makes sure the power off routine is in memory before stopping the file systems.  Make sure you are using the latest version of acpistat.exe.
