You need to right click on the panel in a blank part, select Add to Panel...
From the dialog box that appears, then select Shut Down...
Then click the Add button and then Close.
This happened recently to my girlfriend's Ubuntu laptop, so she had to
do the same to get the shutdown option back.

I recently upgraded my Acer Aspire One, which seemed to go ok, but on
the top panel, the drop down menu Icon that looks like a circle with a

impossible, unless I use the On/Off button. Anybody know how I can get
it back, please.......
