I can suspend to disk (Fn-sleepbutton, so via BIOS, to a preallocated file on 'C:') on the Armada 1500c, and sometimes do to preserve state over a few days, but suspend to RAM is very much faster, startup < 10s even with a Celeron 300 (albeit only 160MB RAM). Also, suspend to disk on hitting critical battery low can be a bit hit or miss. > I never tried acpi. I don't mind if only APM works, if it does, but finer power control would be nice (again towards running on battery for lengthy periods), with quite a few browser windows, edit and console sessions on the go, very seldom rebooting. > The T30 is a bit chunkier and heavier than other T series, but overall > I was happy with it. Thanks, Ian
