I'm experiencing the same bug on a ThinkPad T420 with up-to-date Ubuntu Natty. Please reopen.
The bug is very serious. Just like others, I learned about it the hard way: closed the lid, put my laptop inside the bag, took it out about half an our later, and was shocked to see the laptop heated like on fire, and the fan running full power. Also, the CapsLock light was blinking. This issue should be mentioned in the ReleaseNotes, as it possibly can damage hardware! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/625364 Title: lenovo/thinkpad R400/R500/T6x/T400[s]/T500/W500/W700/X60/X200 suspend fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/625364/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
