No, I think this is not necessary to use screensaver on walkman.
With the operating system on your laptop comes a help function. You find it in the configuration, start - configuration. Of course if you want to use a personal picture you would have to load it first on to your laptop.
To draw forces acting on a pen, you can use arrows to represent the direction and magnitude of the forces. For example, if the pen is being pushed down on a table, you can draw a downward arrow to represent the force of gravity acting on it. If there is an additional force pushing the pen to the side, you can add a second arrow in the direction of that force.
Take out battery and use a tool to push it out. If all else fails use pliers to open gap where pen is inserted.
If yes, draw the forces. You may use arrows to represent these forces.
A ruler and pencil/pen work very well.
Use the pen to draw a face on the box.
If yes, draw the forces. You may use arrows to represent these forces.
if you mess up you can erase it
