Problems with hibernation

I am having problems with sleep and hibernation.  I cannot get out of either mode.  I have turned them off, but when the computer lid is shut, the screen will go blank and I cannot get it to come back on.   I have to hold down the power button and then when I turn it back on again it shows the screen indicating the computer did not shut down properly and to choose which mode to start up in.   What am I doing wrong?
