Note I removed the duplicate link (to #1275621) as the other link doesn't mention NVIDIA and it isn't a Dell machine, I suspect that the NVIDIA chipset is the problem.
For the 4 years I've owned my E6420 I've failed to get reliable suspend/hibernate behaviour, I always turn the laptop off when I want to change location. Sometimes it'll suspend once or twice, sometimes it fails the first time. A failure can mean that it tries to suspend and then wakes up (sometimes having completely shut down - power light off, no activity...then a few seconds later it wakes up) or it'll start to suspend and then freeze on the console screen (having shut down Cinnamon). After a suspend it is hit or miss whether wifi is working. On occasion the Suspend does work correctly but I can't narrow down the conditions that make it work, it can fail (either re-awakening or freezing) if I try to Suspend just from a fresh boot. A year back I changed the behaviour so it'll only Suspend if I hit the power button and click Suspend (if I close the lid it'll just keep running), that way I can't accidentally close it thinking it might suspend correctly. Since it only Suspends if I click a button I'm confident that there's no odd hardware interactions (e.g. a laptop- closed sensor that's dodgy), as after I click Suspend I wait to see what happens without trying to close the lid. I'm using E6420 Bios A19 (from late 2013). This bug affects me right now (I tried Suspend again last week - same problems occurred). I'm running Linux Mint 17.1 (I've been using Mint for 2.5 years). I started with the official Ubuntu 10.10 Dell installation from 2011 when I bought the machine, that never successfully Hibernated or Suspended either. I've never used apport or other crash report tools, I'd be happy to do so if this might help? -- 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/1297049 Title: [Dell Inc.
