Comment 0 for bug 1331077

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.

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.
