PC-BSD command line approaches to sleep (suspend to RAM) and hibernate (suspend to disk)

Question

Background

Lumina offers a Suspend option, which works.

KDE Plasma 4 offers Sleep and Hibernate options, neither of which work.

As suspend to RAM can work with Lumina, so I'd like to try the same with KDE.

The question

Are there command-line approaches to sleep (suspend to RAM) and hibernate (suspend to disk)?

Software

PC-BSD 11.0-CURRENTMAR2016 (based on FreeBSD) with upower and Lumina release 0.8.8_2,1.

Hardware

Apple notebook, early 2011 MacBookPro8,2

It's currently without a battery, so hibernation is particularly desirable. (If I can get sleep or hibernation to work with KDE Plasma 4 on PC-BSD, then I'll arrange a replacement battery.)

FreeBSD 10.2 manual pages:

Maybe https://wiki.freebsd.org/SuspendResume will help on how to use the CLI on FreeBSD or derivatives for suspend/resume. — schaiba, Mar 11 '16 at 11:30

Thanks to @schaiba for the hint.

Option -h does not work as described in the manual page –

– but sleep mode 3 can be tested:

… the CPU context is lost and memory context is preserved …

The wiki directs users to test without X.

It's also possible to test whilst the X Window System runs so, for example, in a terminal window:

sudo acpiconf -s 3

If, following sleep, the resumed screen is illegible, a press of the power button may perform an ACPI shut down.

Hibernation

My test of sleep mode 4 with a MacBookPro8,2 effectively stopped the computer, with no resume, but according to the wiki that's expected with FreeBSD:

… We don't yet have the necessary infrastructure in place to make suspend to disk work on amd64 or i386. …

At http://web.archive.org/web/20130705054229/http://laptop.bsdgroup.de/freebsd/index.html some of the compatibility list content is archived. Not all – for example, of the three listings for Apple products, two of the linked pages are not archived.
