The Suspend/Resume smoke test - Case ID: snr-001 (http://testcases.qa.ubuntu.com/System/SuspendResume) does not work, the screen goes black the laptop seems suspended, but as you move the mouse you get the prompt for password and you go back to your session but network is not working anymore, can't activate it had to restart network manager from command line. The Extended Suspend/Resume test - Case ID: snr-002 does not work: letozaf@HP-G62-Notebook-PC:~$ sudo /usr/share/checkbox/scripts/suspend_test --full This script will attempt to suspend and resume your computer a number of times. Should the machine fail to resume, first attempt to manually resume it. If that fails power your system off and on which will generate an apport bug report automatically.
