--- Comment #2 from Dan Furlani <dan.furl...@earthling.net> 2012-05-28 06:08:33 --- I *did* make some progress with hibernation however. Maybe this info gives hints to what's happening with suspend. The uswsusp Ubuntu package provides s2disk and modifies the power menu items to use it vs. the pm tools (iiuc). I installed it and also upgraded to the final 3.4 kernel (vs. before I was using 3.4rc6). In /etc/uswsusp.conf there is a "shutdown method" line. I get different behavior depending on whether it's set to "platform" (default) or "shutdown". With "shutdown method = platform": - The system will not power off when I hibernate. I have to force power off. - When I power on to thaw the system, a slightly-different BIOS/splash screen is shown that doesn't have the F2/F12 text at the bottom. This seems sensible. With "shutdown method = shutdown": - The system powers off by itself on hibernate. YES! - On thaw, the regular boot BIOS/splash screen is shown. Not a problem though. The other thing I figured out is that if the laptop is plugged in, it will reboot instead of powering off. However, if it's unplugged and just running on battery power, it powers off successfully. The bottom line is that hibernate works perfectly now as long as the laptop is unplugged. I did some experimenting with setting /sys/power/disk to [platform] vs. [shutdown] but it didn't seem to make any difference to anything. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
