I have been having this problem for a past few weeks. 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.
Thank you
