According to http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/E540-Suspend-Resume-failure/m-p/1803308#M32836 Lenovo finally is willing to investigate the problem but only if someone with an special model of the E540 with one of two specific Linux version calls for help. Maybe one of you fits that profile?
"I understand that on a technical level, Linuxs distibutions share the same bones, which is how I will open the case for one distro and resolve the issue for all. The problem lies in what Lenovo supports. My next level support cannot accept a case opened on anything other then the two listed - RHEL 7.0 or Ubuntu 12.04.02 on model 20C6-Z049US (Thanks Mahene!). I can't change the rules, but I can use them to drive a case. If you are running either of these versions on this model, experiencing the issue as described in this thread, and willing to assist, please PM me.

I recently upgraded to a new BIOS v2.07 [1], I think the problem exists since then. Update ====== I confirmed that this is definitely a BIOS issue. The last working BIOS is v1.61 [2], so the change was introduced by v2.07 [1]. Installing the latest v2.08 [3] does not fix this problem. So this is the changelog for v2.07 [1]: - (Fix) Fixed an issue that system will auto wakeup after shutdown when battery capacity is under 15% on DC only. - (Fix) Fixed an issue related to APS. - (New) Added support for new GPU config. By the way, I could not find a new GPU config option in the BIOS, same old choice <Integrated> vs. <Optimus>, nothing new.
