Need more information. "Updated our laptops." New OSs? Windows 10? New AC version. Off the top of my head, I would guess it has something to do with the OS. Somewhere controlling the font size. Are your icons smaller as well.
Depending on your OS, there are a few places to change font size. Type font size in your search or run box. I don't think you can fix it with resolution. That affects everything. Would need to just be the font. Have you tried Enlarge text box? That would be a temporary fix for editing the chart. May not help read the note. On View draft, you can zoom to 200%. Again, not optimal long term. I am assuming your updates haven't affected other programs.
