[Kernel-packages] [Bug 1295382] Re: Dell Latitude E7240 does not resume from suspend
I did some more digging and realised that this was due to a misconfigured BIOS - I'd been too aggressive in disabling hardware to save power. Once I restored it to the default setting, suspend/resume works fine - from the pm_trace logs I suspect the issue was that I'd disabled the serial port. I'm happy for this bug to be closed, or changed to a lower priority. I'll rename it to reflect the actual bug. ** Summary changed: - Dell Latitude E7240 does not resume from suspend + Dell Latitude E7240 does not resume from suspend with non-default BIOS settings (when serial port is disabled?) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1295382 Title: Dell Latitude E7240 does not resume from suspend with non-default BIOS settings (when serial port is disabled?)

No, I've never had this working.
