Yes it should. When I went to an apple store to replace my battery that started to inflate, they asked if I wanted to juste completely remove it or get it replaced.

But don’t forget that without the battery, once you unplug the laptop it is like removing the plug of a desktop computer: everything goes off instantly.

Seems the step I was referring to are no longer there!

Step 4, 5 and 6 are useless for changing the PRAM battery..

This tutorial should be avoided as possible, the Cybook Hardware is NOT MADE to charge such a battery, you risk fire/explosion problem by doing that..

Never mess with battery that are not made for a device
