> Do you mean a fully charged battery only lasts 4 ~ 6 hours? I will do some other tests next days but if a suspend my laptop at 1:00 with a battery loaded about 40%, when I try to resume at 7:00, the laptop refuse to resume (battery empty). I have to plug in the charger in order to resume (normal boot because a halt was certainly requested by the system on battery low).
With : $ sudo sh -c 'echo mem > /sys/power/state' $ sudo sh -c 'echo deep > /sys/power/mem_sleep' the problem disappears. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810619 Title: Sleep mode doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1810619/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
