Wakeup after Power Off
« on: 2009.03.27, 17:36:26 »
I set up a number of systems, and I like to have them power off at system shutdown. Under the old IBM APM driver and the new eCS ACPI/APM drivers, I usually could get this to happen.

But on more modern systems, I've been seeing a new behavior on power off. The system powers off as I think it should, but then it wakes up one or two seconds later. One system needed to have jumpers reset on the motherboard relating to powering up in response to a USB peripheral.

Now on my latest system, based on an Intel G41 chipset, nothing in BIOS nor any jumper on the motherboard make any difference. The system always wakes up after a power off. Nothing on the interwebs suggests that Linux or Windows have any problem shutting the system down.

Even poweroff.exe supplied with ACPI 3.14 does not avoid wake after power off.

Any ideas why this is happening? Does anyone have a ticket already with this problem?

OK, I've created ticket #395

http://trac.netlabs.org/acpi/ticket/395

If I boot MS-DOS, it shuts down just fine.

Hi Neil,

sorry for posting this late, was busy.
Yeah, I had the very same problem with a new machine here. eCS 20rc6 (note: not "-a") was unable to shut down, regardless what application (styler, x/e-center) was used. I reported it to Eugene who turned this into a Netlabs ticket. rc6a also failed with out-of-the-box driver levels.They pointed me to a new version of [ACPI-something] I had to download which fixed these problems wonderfully.
See ticket for further reference: http://trac.netlabs.org/acpi/ticket/373

I downloaded ACPI-APIC-BAT.zip from BetaZone, and it does work for me, too. My computer shuts down successfully. The debug output kind of obscures any boot messages from loading drivers, etc.

Thanks, WarpCafe!

Hey,

good to see that my post helped and glad it works for you! :)
I suppose these debug info to vanish once we have a stable GA release of the stuff (...which, as we all know, is another story on its own... ;) ).

Cheers,
Thomas
