I have been using this system for almost 1 year. I use with the power setting to suspend my system when I close the lid. In the past few weeks sometimes when I close the lid, the system doesn't gets suspended. Instead, it gets stuck. When i reopen the lid screen will be back and nothing can bring the system back. I have to restart the system by pressing the power key. No key is working during this state. I tried pressing num lock and no response. It happened rarely before. But for past few days, my system has been getting stuck like this more. Before this, I used to have system crash suddenly and lose all data without any reasons. I am fairly new to ubuntu I don't know how to diagnose these things. Please help me.
