\015 Computer monitor screen goes black after 20- 30 minutes and computer is still on.....sometimes to power it off i have to take out the battery.\015\012any solutions as to what is the problem and how i can fix this?\015

Answers :

This could be due to the power management settings in your notebook. I suspect that the notebook is entering either in to sleep or the screen saver is set. Check if the issue persists, if these are disabled.....
Go and check the power setting in the control panel. it may be set in there
