Title: [Lenovo ThinkPad Edge E540] suspend/resume failure Status in “linux” package in Ubuntu: Incomplete Bug description: suspend to RAM failed before it was completed: * fan was still on and * Fn-F1- & Fn-F4-status LEDs were still on (signifying muted speakers and microphone respectively) * nevertheless the general ThinkPad LED (the i's dot) (/proc/acpi/ibm/led 0) behaved like normal: slowly blinking, which normally means "I'm suspended to RAM." * however resume was impossible: wakeup failed through mouse clicks, various keyboard keys and combinations and also the power key, only a hard reset (5s or so holding down the power key) could bring it back to life I already checked the latest mainline kernel for trusty v3.14.1 [1] and the problem still exists there (unlinke Bug #1304043). Adding the kernel cmdline option acpi_sleep=nonvs was of no avail, too. I recently upgraded to a new BIOS v2.07 [2], I think the problem exists since then. Update ====== I confirmed that this is definitely a BIOS issue. The last working BIOS is v1.61 [3], so the change was introduced by v2.07 [2]. Installing the latest v2.08 [4] does not fix this problem. So this is the changelog for v2.07 [2]: - (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.
