Actually, I've never tried it on C600 but on C500 it worked well,
the same as for CP/CPi...
first of all, download this:
If that won't help try to find better DSDT at
and put it into /boot, then add following to /boot/loader.conf
acpi_dsdt_load="YES" # DSDT Overriding
acpi_dsdt_type="acpi_dsdt" # Don't change this
Of course, you should load "acpi.ko" at startup.

Power button? Not sleep button?

Try the latest BIOS update available from Dell. It's their bug since they
implemented ACPI: BIOS tries to initialise external monitor even there's
none of. Try pressing <Fn>+<F8> (CRT/LCD) and everything should be OK.
Better way is yet to upgrade your BIOS to latest available.

In console you can use "apm -l"
(ACPI provides some backward compatibility with APM)

I prefer Enlightenment, so I can't say for sure, but most utilities
using APM interface should work.
