to get the acpi powerbutton event one needs to press the button for more then a second, is this a thinkpad-acpi limit or a limit by the embedded controller?
It is standard to have to hold that button for a while, usually 3s, before it will signal anything to the operating system. Some BIOSes let you choose between delayed or instant-off, and what kind of signal (shutdown or "sleep") the button should issue.
If it is the former could this maybe be adjusted? I thought it was an acpi problem that I got no shutdown when pressing it.
Look in the BIOS. I don't recall if the thinkpad lets you change it. And this is standard, generic ACPI functionality, controled by the acpi "button" driver. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So there is no code in thinkpad-acpi that encodes how long one has to press the button?
No. There isn't such code *anywhere*. It lives in the BIOS or the EC (could be in the ACPI DSDT, though). _______________________________ So the hardware vendor decided upon this and we can't do anything about it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
