I tried the combination CTRL+ALT+L or L but it is not working. But if I select the menu item Lock screen from the Setting drop down it works.
Any thoughts on how to fix keyboard shortcut?

In the top panel right corner choose System Settings to select Keyboard in the Hardware section, or type "key.." in the Dash then select Keyboard:
In the Shortcuts tab all key combinations are listed. You may change them there or add your own custom shortcut. To have the poweroff shortcut back add it with a custom shortcut for the following command:
gnome-session-quit --power-off
Note: to be able to add a custom shortcut we may have to clear an already existing shortcut if this uses the same keys.
The GNOME lock screen feature depends on the gnome-screensaver . In case you have removed it or did not install it in a custom environment you will have to install it first.
