More precisely the kernel calls itself 2.6.8-24.5-default which translates to rj@sol:~> cat /proc/acpi/info version: 20040715 Now one should know, that the previous 2.4.26 kernel, with APM worked good for my needs which was to be able to send the machine to some suspend-to-ram mode when closing the lid and bringing it safely back again opening the lid. Now well - ACPI is default in the distro so I went for some configuration. The good news: I finally managed to get the machine to go to S3 when closing the lid and it also comes up relatively safe again (after garbling the screen a little bit and some slowness for the first 10-20 seconds after resume). Also, S5(?) seems to work when pressing the suspend-to-disk button it purges unnecessary blocks and saves the content to swap. On boot it recognizes there is something in swap and restores the saved state. End of good news. * S1 doesn't do anything. Well ok - let's look at the others. * Closing the lid, the machine goes down and the "moon"-led goes on indicating the suspend state. All is quiet, however, the machine generates significant heat. Examining the situation, all fans, the HD etc. are switched off, even the display, but some second after the display has been switched off completely, THE BACKLIGHT GOES ON AGAIN! Uhhh... So after 2hours in this "suspend" mode, the battery is just 70% charged. (Took 8hours with APM) Even worse, the external (USB Radio) mouse doesn't work anymore. Neither did the ethernet (e100), but somehow I managed to configure it (mungled the PCI latencies of the ethernet controller), so that ethernet is not lost after S3 resume. And there's no way to bring the mouse back to life again but reboot. The internal PS/2 mouse (trackpoint) works fine. * S5 works as described, unfortunately after resume, the clock shows exactly the time, when the shutdown did happen. -------- -- best regards, Dipl.-Inf.
