A good mechanic always has parts left over
It is time that I come clean and confess that I steal screws. I don’t intend to steal them, but while I am working on a computer, I tend to put the screws in my pockets so that I don’t lose them.
When I get home at the end of the day, I always find a computer screw or two. To my defense, I always put the computer completely back together.
I place the blame on the computer manufacturer. Today’s computers have way too many screws. Some computers have two thumb screws to hold the side on and two screws in each side of the CD-ROM drive to hold it in place. These screws are in addition to other types of securing mechanisms like clips and grooves.
