When battery is critically low system suspends and then immediately wakes up to unlock screen. Reproducible: Always Steps to Reproduce: 1. Work on laptop until battery is critically low and wait for auto-suspend. Actual Results: Laptop suspends and then wakes up. Expected Results: Laptop just suspends. If i leave laptop on battery power it suspends automatically after period of time and not wakes up. Such behaviour is only for auto-suspend on battery-low. Active typing and clicking just before auto-suspend may be the cause.
I am using kubuntu precise with KDE 4.8.3 from kubuntu ppa
I can not choose 4.8.x version in 'version' for this bug because it is not listed for some reason.
This is not a KDE bug, this happens also with Windows (tried on my two netbooks) I think it's a normal behaviour of every bios
Yeah, there's probably nothing that can be done about this at the kde level. Try looking at /proc/acpi/wakeup (google has plenty of info on this) or see which devices are set to wake the computer in the bios. Support channels for your distribution or the kernel might be able to offer more suggestions. Maybe the kernel could make sure that the input devices are quiet before suspending? I don't know. Anyway, I'm provisionally closing this unless someone can come up with something powerdevil can do to alleviate this problem.
