Alternatively, use the physical button to put the laptop to sleep.(choose what pressing the power button does)
Re-install your graphics drivers.
OR do a clean install of windows 8.1 and make sure you have the correct graphics drivers installed.
- Check that you have not created any custom power plan(just below choose what closing the lid does,if you have delete it).
If it still doesn't work, might be a hardware issue and you will need to take it for repair.
Check the Windows Power Options. Look at "Choose what closing the lid does" and make sure the setting is correct. That would be the most likely cause.
Update the Power Management driver to the newest version also.
