Ubuntu 14.04 - Blocked after suspending

гve updated my Sony Вайо PCG-3C1M to Ubuntu 14.04 and since then I have this issue, when the laptop goes for приостановка, usually when the screen is closed, the laptop can't "wake up" after that.

After the screen is closed if you open it again it is blocked, without the login/password screen, and after 40 secs or so, it goes to black screen and I have to restart the laptop.

• Does anyone knows the solution for this?
