...saying I can do it only with the aid of my screwdriver?
I have been sucessful with a hammer and a wrench, but yes it does require a physical action on the motherboard. Some (typically older ones) would reset if the battery was removed for a significant amount of time. Most require an action such as pressing a small button, moving a jumper, etc.

If you have the hardware manual for the computer, you may be able to do it yourself, otherwise follow KdrKane's advice.
