Well, properly or not, everything I tested short of detailed benchmarking since -test3 has had no problems and always reported stats fine. > Anyway, you might want to simply implant old tables into kernel, and > use them... Possibly even doing union. Thanks. I vaguely remember trying something like this, for a completely different and forgotten issue, when I first started playing with ACPI. It turned out to not be necessary so that file has been erased from my memory and apparently over-written too much to be recovered. It seems the new BIOS has also given me better backlight and IDE power saving support (translation watching DVD's while on battery now sucks). It seems as if I'm going to have to become an ACPI expert to get some control over what this thing's doing and when. Like, it suspends fine in Windows but not in Linux. (Actually, it suspends fine in Linux too - It just won't wake up.) Can you point me to some references that will help be build my own tables without burning my machine up? > Pavel > -- > When do you have a heart between your knees? > [Johanka's followup: and *two* hearts?] And I've been puzzling over your sig since I first saw it.
