Subject: [acpi-jp 2517] ACPI on Dell Inspiron 8500
Sender: owner-acpi-jp@jp.FreeBSD.org
X-Originator: bruce@cran.org.uk
X-Distribute: distribute version 2.1 (Alpha) patchlevel 24e+030702

Now that the ACPI on the 8500 mostly works, I was wondering if there's anything
more which can be done to the DSDT to make it work 'better'.   The recent 
acpica import hasn't fixed the warnings about zero length buffers when using
the unpatched dsdt, but the only actual error with the patched version is about
the second battery initialization, which makes sense since there's no second
battery installed on 8500s.   While running Windows XP and speedfan, I've seen
events being reported such as 'battery high, 80%, battery medium, 50%, battery
low, 20%', but it appears that since there's no ec on the 8500, no battery
events get reported and when the battery runs out the computer just loses power!  
Also, I've seen that the Dells can report the temperature of system, hard
drive, DIMMs, and CPU - but I only get the system temperature with the FreeBSD
acpi.
Is this something which can be fixed using an ASL patch, or does Dell just do
the whole acpi thing differently?   Also, suspend still doesn't work - 
on my computer, the machine seems to suspend but immediately gets woken up,
but the screen stays blank and the computer has to be reset - it used to be 
that I could reboot it using Ctrl-Alt-Delete, but that seems to have stopped
working now.  Running
'acpiconf -s 3' over a serial console results in a panic in the syscons driver.
If it's useful I can send a log of 'boot -s -v' with hw.acpi.verbose=1.   
Apologies if this has already been discussed on the mailing list, I've not 
seen any messages about the Dells since the initial ASL patches a few weeks ago.
