Andrew,
sorry to bother you with mailing directly but I subscribed at the 
linux-pm-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org and sourceforge seems to not accept
mail 
from me. Tryed with acpi-support too but nothing. So I choosed to mail
you 
directly becouse it seems you are the main ACPI developer.

Hi to all!
I have a compaq laptop (evo n1020v, 
http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/321957-64295-89315-212727-
f1-240898.html) 
and I'm trying to get power management with this.
Tryed with ACPI (latest 2.4 patch included in 2.4.21-pre[12]) , the BIOS

passes the blacklist check just fine. With acpi I get the battery time
left, 
events so I can poweroff with lkaptop's power key and the two termal 
controlls. Now, reading /proc/acpi/sleep I get this modes:
S0 S3 S4 S5
But trying with echo <n> > sleep I can only poweroff with S5. The other
values 
for sleep do nothing, tried with debug enabled too and nothing in the
logs. So 
I can not get the 
laptop in sleep or hybernate.
With APM when doing "apm -S " everything is fine, the laptop goes to
sleep and 
wakeyps when pressing some key. With "apm -s" The laptop goes in
hybernate 
but I can't get it awake, I have to shutdown it pressing the power key
for 4 
seconds.
As It seems that this laptop's ACPI/BIOS is good, is there any chance to
get 
sleep 
/ hybernate with ACPI on this laptop? This will be the best option if 
possible. And yes, I accept patches for this and I'll gladly try them
and 
report if needed. If not, is there any way to wake up this laptop after
a 
"apm -s" ?

I'll provide any needed info, just ask. And sorry again if you are not
the 
person to ask for this.

Thank you for your attention,
Fredi

S3 and S4 are not supported in ACPI for 2.4.x (S0 is running and S5 is
soft-off).

try swsusp for hibernation:
