Comment # 8 on bug 1190414 from S. B.

Thanks for reminding me to close this bug. It was actually a bizarre issue with
the new laptop hardware design (or lack thereof). Apparently it uses a magnetic
sensor in the palm rest to detect if the lid is closed instead of the
traditional lid hinge switch. The sleep events were caused by me resting my
tablet with its magnetic-closing case against the palm rest just to the right
of the trackpad, which triggered the normal Linux sleep-on-lid-close event.
