Sorry, PEBKAC error, it appears I've been replying off-list.
Please find below my response. It appears that the latest problem is something
to do with X as it crashes out when trying to return to the console when
pressing Ctrl-Alt-F1 too.

</div>Thanks for the help Kevin, I'm quite new to FreeBSD. I noticed the sysctl
for lid_switch wasn't set, but I just thought it was for information only. man
8 sysctl is my friend.
Sleep now works, it just won't wake up. I've debugged this kind of thing before
with Linux so I'll plough on from here, I expect I'll just have to work out
which systems are shut down at sleep and which ones are restarted afterwards.
I've had issues with sound modules doing this kind of thing in the past. I
think a serial console might be in order.
The battery thing is really odd as it's a virtually new battery, and I wasn't
aware there were issues before the install. However, the thing won't charge
when it's switched off, which screams HARDWARE! It's probably one of those
black swan situations.
Thanks again for taking the time out to help. It's really appreciated.

Could you provide the output of:

S3 is suspend to RAM, S4 is suspend to disk, and S5 is shutdown
Power button will do a system shutfown and power off
Sleep button will suspend to RAM. Little power use and supported by BIOS with
minimal OS support. Works on FreeBSD
Closing the lid does nothing in BIOS. Display backlight my turn off, but that's
If the power management system wants to go to a standby mode, nothing happens.
If a suspend is requested by the OS, suspend to RAM is used
Delay 1 second for OS to do preparation for suspend to RAM
BIOS does not support suspend to disk. OS support is required. FreeBSD does not
have this support.
Power saving Cx states are NOT enabled.
ACPI will update temperature information every 10 seconds
Thermal zone 0 is 39C. This is usually the CPU. 39C is VERY cool. Hopefully it
ACPI is NOT throttling the CPU to control temperature
ACPI is not increasing system cooling capability (usually the fan) to reduce
temperature. NOTE: This does not mean non-ACPI controls are not used!
At 95C, turn the cooling (fans) to maximum.
At 98C, throttlethe CPU to reduce temperature
hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
Odd that tz0 and tz1 are both 39C. Seems unlikely. May be different CPU sensor
or something else.
At 98C, power down (if supported). This is different from the hardware shutdown
on severe overtemp that simply kills power.
hw.acpi.thermal.tz1._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

OK. It's dead.

It's not discharging.

It is at 7.9 volts which is too low to run the system.
Since the system appears to be on AC power, but the battery is not charging,
something is wrong here. I have no idea what.
It appears that either the charging system or the battery has failed.Neither
involved the OS, but indicates a hardware issue with the device.
There are several ACPI variables I don't recognize or am simply not familiar
with, but this will give you some idea what many of the important
ones are. Remember that ACPI is firmware and may have errors that result in its
lying to the OS. I don't trust some of what I see, especially the temperature.
Most laptops idle at between 50 and 60C. Seeing two zones at 39C
is very odd.
