Keith_rob657 this is a link to a free Service Manual,

Go down to the bold heading - Travelmate.
Go down to the last line, (Begins with 7730A), and left-click on -
C110

(The Acer TravelMate C111Ci is one of the TravelMate C110 series of Notebook PC's)

This is a PDF file. It may take as long as 30 seconds before the first page will come up.
It may also take additional time for the file to fully download.
(The computer you are on now has Adobe Reader on it, which uses PDF files)

At the top of the PDF file is a page number box. It is to the right of the blue Down Arrow.
This is the page number I will be referring to. Not the actual page number.

Go to Page 69.
RTC Battery Removal.
(The Real Time Clock battery is the CMOS Battery)
