Hi, The motherboard is an Intel DH77DF (sorry, not a Gigabyte as incorrectly wrote in the other post). The CPU is an Intel Core i7 3770K.
The dmidecode commands don't do anything. Running it without parameter gives: root@hades:~# dmidecode # dmidecode 2.12 # No SMBIOS nor DMI entry point found, sorry. Looking in the BIOS directly I have the following information: Desktop Board DH77KC - BIOS Version 0069 - 02/24/2012 (I never did a BIOS updated on this board, it worked fine before, including working suspend/resume under Ubuntu 12) In case it's relevant, here are also the BIOS Power settings: Intel Dynamic Power Technology: Custom Enhanced Intel SpeedStep Technology: Enabled OS ACPI C2 Report: Enabled OS ACPI C2 Report: Enabled System Power Options: After Power Failure: Power On Deep S4/S5: Disabled Wake on LAN from S4/S5: Power On - Normal S3 State Indicator: Off Wake System from S5: Disabled PCIe ASPM Support: Enabled Native ACPI OS PCIe Support: Enabled Flash Update Sleep Delay: Disabled -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1417220 Title: After upgrade from 12 to 14.04, suspend/resume doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1417220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
