I'm out of home city now. It's really interesting, I've tried just to add two methods to original acpi_sony and that have no any effect with correct power off. However modified sources provided via link in my previous post - works. Have you tried it? I'll try to downgrade modified sources to find out why it works. It performs more sophisticated initialization of SPIC, but SNC is handled almost in the same way is in original (lan power management are SNC methods, not SPIC, which is operated not through ACPI). --- Best regards, Alexey Tarasov On Mon, Jun 9, 2008 at 7:31 AM, Martin Pieuchot wrote: > Hi, > > I tried to add the lan power control to the acpi_sony module.

Also, different series of Sony laptops are rather different in ACPI methods (e.g. C series and SZ series) Modified sources are inspired by Linux sony-laptop driver. duplicates initialization code of SPIC, event handling and so on. However - AFAIK - linux driver does no special tricks at power off stage, it is just dettached, device file in /dev destroyed in so on, but Linux (Ubuntu 7.10) it still possible to power off correctly. --- Best regards, Alexey
