The behavior is still the same after I updated the BIOS (which was quite a pain, by the way because the Lenovo BIOS update ISO only works on CDs and cannot be booted from USB drives. Thus I had to install Windows to install the update and then install Ubuntu again).
Here is the output that you wanted to have: GJET75WW (2.25 ) 03/28/2014 As I said, nothing has changed. Sometimes (not always) when going to suspsend, the screen goes dark, the LEDs indicate suspend mode and the cpu seems to be working so that the device gets very hot very fast. This is why I think the bug should have a higher importance level than "Low" because it can lead to the device overheating. It is not possible to recover the system from that state. Holding the power button until the device powers off seems to be the only way to get out of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315316 Title: [Lenovo ThinkPad T440s] suspend/resume failing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
