So, I bought a Thinkpad X1 Carbon and put Ubuntu Gnome Remix 12.10 on it. I've had an issue. Sometimes, the device will resume from its sleep state automatically. This has happened both under Windows and Ubuntu. All updates applied.
I have no idea what causes it, and the resume tends to happen some time (~1 hour) after: a) I choose "Suspend" from the Gnome menu. b) I unplug the machine from power.
This has occurred twice under Windows with Automatic updates disabled. This has occurred at least 4 times on Ubuntu and I cannot recognize any pattern other than each time, I had a lot running. For example, stats show
RAM: 3.0GB (84.6%) of 3.6GB
SWAP: 3.8GB (47.5%) of 7.9GB
My theory is that after some time, it tries to hibernate (though it is disabled and I am unable to enable it in the menus). 'pm-hibernate' allows me to lose my work when I turn on my computre.
I have tried upgrading to Kernel 3.6.6 to see if any changes occurred, no change.
One peculiar note, the laptop itself blinks the 'moon light' while in sleep and documentation states that it will keep blinking as long as it is in SLEEP. This happens in Windows. In Linux, this stops after an hour or so, however, the system usually restores without issue from the sleep state.
I apologize for the long read. How can I troubleshoot and which logs are useful? I have made a copy of all in /var/log/.
Thanks you very much
In the Bios, in the category "Power", there is a feature called
Intel (R) Rapid Start Technology
Which tries to enter a more efficient sleep state after being asleep for (by default) an hour. You could try to disable this option.
