[Lenovo Yoga 2 Pro] Resume fails when on AC power

[Tim Ryder]

laptop: yoga pro 2
running Ubuntu 14.10, also happened on 14.04 - all 64 bit

Laptop fails to resume after being suspended only when on AC power. When on batter power suspend/resume works fine.

When on AC after resume you can move the mouse and see you desktop but nothing is clickable. Only way I have been able to get around this is to switch to a different terminal and reboot the machine.

I installed the latest upstream kernel and I am no longer having the suspend/resume lockup issue. It looks like it is fixed in the upstream kernels. Thank you for your help on this.
