Re: ACPI suspend/resume

Did you read any ACPI docs?

should do the trick.
But this will *sleep* only.
ACPI does NOT support suspend-to-disk, only suspend-to-ram (still
needing power!!)

Well, suspend done by BIOS will take much longer, as it also has to
write memory to the disk. But it needs to write the complete memory
(swsusp does not) and it needs to do that in BIOS mode, thus much much
slower... i guess a real system bootup is much faster than a restore
from disk in BIOS mode...

well, i'll stay with 2.4.18 for now.

I don't think any authomatic CPU throttling is yet supported, at least
not by the 2.4.x series without additional tools.
Did you read that "Tips on Notebook useage" page? Sorry, i don't have
the URL - about using noflushd and not using journaling?
