Tsvetomir Dimitrov, thank you for reporting this and helping make Ubuntu
better. Could you please test the latest upstream kernel available from the
very top line at the top of the page (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
kernel, please comment on which kernel version specifically you tested. If this
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested exactly
shown as:
kernel-fixed-upstream-3.18-rc2
This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
[Lenovo ThinkPad E440] Ubuntu 14.04 doesn't recover from suspend
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After the system is suspended it doesn't recover. The screen remains black,
the lid still blinks (indicating that the laptop is suspended). The power
button also doesn't start the system.
Bios version is 2.16.
A workaround for this problem is to disable USB3 support from bios. The
problem is similar ot bug report #1331077.
