Do you mean the status bar on the bottom when referring to the laptop and it's not there on the desktop?
The status bar is the thin bar just above the bottom task bar, as seen in the screenshot below. Zoom is the magnifying glass/number/drop down arrow on the far right of the status bar.
This is for Internet Explorer.
If this is the bar you mean and it's not there, easy fix to make it appear if you are using Internet Explorer.
If the menu bar is present at the top of your page (File, Edit, Favorites, Tools, Help) click View/Toolbars/click on Status bar.
RIGHT click on an empty spot just above the address bar or tabs bar, then click on Status bar.
