Before beginning, I would suggest that you initially remove the RAM module from the system (if you have one). This can be done by removing the strip above the keyboard, and lifting the keyboard. You then need to remove the little screw from the module, and take it out. Now, Flip the Libretto over, and remove all the screws from the underside. Then remove the cover carefully
Now, you can see the little green RTC battery.
Flip the Libretto back over carefully, and unplug the RTC battery wire, which can be accessed under the keyboard
Now, the RTC battery should easily come out
Now you can just reverse the logic to fit an RTC battery. Transplant done!
