ACPI power saving
- There is a possible bug in the Linux kernel that causes Optiplex GX240's ACPI mode to be forced to ht (hyperthreading), however this prevents ACPI to power down the computer on shutdown, halt, or powerdown. This problem is present in the 2.6.19 Linux kernel and likely others. To fix this see.
