I don=C2=B4t have any experience with ibm-acpi yet, sorry

The main thing for me is that I want to close the lid, and open it as often=
 as=20
I want without any problems. The wake up takes about 3 seconds until all=20
services & modules like the ipw2100 or openvpn (which I use to protect my=20
wlan) are up and running.

So I don=C2=B4t need the power button at all (except in rare moments I have=
 shut=20
down the machine - but I never turn it off, except I stay out without it fo=
r=20
more than two days)

The only thing I can say is that during suspend about 1% of power is used p=
er=20
hour. I work with my battery about 3 hours, including a lot of wlan-traffic.

yes thats true. But I don=C2=B4t have the time to play around a lot at the =
moment.=20
APM was much more quicker for me to get it running - with a stable resume.

Here=C2=B4s a link a R51 config page. Based on your distri, you have to cho=

you need.
