Comment 14 for bug 61201

Same problem on a couple of laptops they were working as expected then stopped.

Did a fresh install 8.04 then after 100+ updates now not working.

This doesn't just seem to be on critical battery but when it is running on battery power auto suspend & hibernate doesn't work at all.
When ac plugged in works as expected suspending/hibernating after time outs set in power manager.

Tried 8.1 live and appears to have exactly the same problem suspends/hibernates on ac but not on battery power.
