I have the exact same problem with my IdeaCenter A730 and no one has responded to my posts. This problem seems to be common and no one has offered any assistance or feedback.

Further thoughts to help:-
This problem has been caused by Lenovo issuing a BIOS update 1.70 that causes the problem, so Lenovo should pay for your repairs even if machine is out of warranty.
Suggest get Lenovo Service center involved ASAP
Hope this helps.

Thanks for your reply Johnoo -
I fixed my problem yesterday after reading somewhere that it could be caused by an outdated display driver. I downloaded the intel driver utility and used it: http://www.intel.com/p/en_US/support/detect
The utility told me I was using an outdated display driver. I updated the new one, restarted my computer, and now I have no issues. My PC "wakes up" properly from sleep and when the screen goes play, it comes back on after mouse/key input.
