I have been told, and read that acpi are (deliberately) buggy, especially for Linux based distributions. I have not done this test myself, but would be curious to give it a try one of these days.
Suggest there is minimal purpose served by grappling with ACPI, if one is fine-tuning linux, unless there is even-handed ACPI development support for linux. With M$ manipulating their "industry collaborators" to conform to their usual restrictive trade practices what hope is there for a level playing field?
It seems that many brands of motherboards would be constructed by the same manufacture (Foxconn). See the link above...
Sorry, this would seem irrelevant, Melodie. Yes, Foxconn is a huge OEM Chinese manufacturer (>400,00 workers at their largest facility, the one where production line accidents, toxic poisoning and worker suicides have been reported). Each mainboard brand fashions its own style of BIOS, irrespective of where the board is assembled
. For example, ASUS, Gigabyte, MSI, Intel, AsRock, HP, Lenovo, Toshiba, Fujitsu etc etc all differ. Then one factors in chipset type, overclocking/unlocking options, power management etc etc and many other variables. I'm certain others know a whole lot more about this.
