I will add that unsurprisingly these problems exist with the dock as well. I have through trial and error been unable to find a good stable solution with 64bit whether integrated or discrete graphics used. I am going to try the bios update before taking more drastic measures. The ACPI ones echoed those of this bug, however with integrated graphics I have had some more difficult to diagnose problems recently as well. I will also add that while googling around for solutions, it seems there are some Windows issues as well: http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-BIOS-1-25-doesn-t-fix-resume-from-sleep-with-16GB-of-RAM/td-p/444921
My machine does have 16GB of RAM so that may be interesting to investigate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776999 Title: [Lenovo W520] laptop freezes on ACPI-related actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
