I have the same laptop model, which is Ubuntu certified. What is not working - I assume the sound playback?
Can you tell me what happens when you do this: - Shut down your computer - Remove the power supply - Remove the battery - Put back the battery - Plug in the power supply - Turn on the computer and log into your account - Press the Volume Up button (F9) - Open the file "/usr/share/example-content/Ubuntu_Free_Culture_Showcase/How fast.ogg" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/636709 Title: Sound not working -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
