Yes - I didn't make myself clear here. `shutdown -p now` will sometimes cut the power at the appropriate time, sometimes it will not. > > > But it's certainly a whole lot better than it was, so thanks for all your > > help. > > First some diagnostics, please do the following: > 1) On a console: > # uname -a FreeBSD ideapad.piggybox 7.2-RELEASE-p1 FreeBSD 7.2-RELEASE-p1 #0: Sat Jun 20 11:03:21 BST 2009 peter@ideapad.piggybox:/usr/obj/usr/src/sys/GENERIC i386 > # sysctl debug.acpi debug.acpi.suspend_bounce: 0 debug.acpi.do_powerstate: 1 debug.acpi.acpi_ca_version: 20070320 debug.acpi.ec.timeout: 100 debug.acpi.ec.polled: 0 debug.acpi.ec.gpe: 1 debug.acpi.ec.delay: 200 debug.acpi.ec.burst: 0 debug.acpi.batt.batt_sleep_ms: 0 debug.acpi.semaphore_debug: 0 debug.acpi.resume_beep: 0 > 2) What version are you using (I've got the S10e)?

Not that I've been able to determine. I thought at one point that it had to do with the amount of charge in the battery, or whether it was mains connected. But I can't detect a pattern. > 5) What are the last messages printed on the console (when shutdown fails)? Sometimes normal 'Syncing disks, vnodes remaining...' sometimes the correct message but garbled. Whether the message is garbled or not seems to have no bearing on whether the system powers off or not. > > A few things you can try to fix the problem: > 1) Go into the BIOS settings (and just exit, this resets some stuff) > 2) Try playing with debug.acpi.ec.* (especially with delay [remember a value > of 0 disables any delay]). > 3) Upgrade to -current (or try a newer version of the ACPICA driver for 7) > 4) Flash the BIOS to the latest version (released in May) I'll have a play with the debug.acpi.ec.* settings first and check my BIOS version and report back.
