Suspend not working

[Sergio Gutierrez]

I installed HWE package trying to solve issues with the suspend function. However, after the installation, I see that the suspend works randomly. Specifically, it works well when the load of the system is low (just after being powered up with no applications started).

When trying to suspend, the fan and power led keep turned on, but the screen becomes black and keyboard becomes unresponsive. It is not possible to access to a tty. Thus a power-off reset is required.

This issue was happening also with 4.4.X kernels, but with 3.13.0-101 kernel does not happen.

Thanks in advance for the attention.
