If you have debugging enabled - it might be going into the debugger.
Check caps lock - does it work? If so, try doing a 'call doadump' and
hit enter - does the hd run for a while? If it does, when it stops
running, type 'restart' and maybe it will reboot.
On my D810 (which is the same system as the D610 I believe), I can get
it to suspend, but resuming makes the system boot up like it had been
turned off.
I have these settings in /etc/sysctl.conf:
hw.acpi.lid_switch_state=NONE
debug.cpufreq.lowest=500
hw.acpi.video.lcd0.active=1
hw.acpi.video.crt0.active=1
And have played with these two settings:
#hw.acpi.reset_video=1
#hw.syscons.sc_no_suspend_vtswitch=1
I also have this in /boot/loader.conf, but can't recall why:
hw.apic.enable_extint=1
