Same here on my Lenovo X201s (5413FFG, Intel(R) Core(TM) i7 CPU L 640 @ 2.13GHz). It started within three to four of days ago. I received several updates (including new kernel images). So it is hard to trace back. Switching back to an older kernel does not help. My feeling is, that it started when I received some ACPI related packages.
A bug similar to my symptoms is filed at RedHat: https://bugzilla.redhat.com/show_bug.cgi?id=675433 This problem is very serious. I'm not able to use the system for work. ** Bug watch added: Red Hat Bugzilla #675433 https://bugzilla.redhat.com/show_bug.cgi?id=675433 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/370173 Title: laptop overheats and suddenly shuts down/off -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
