Common Methods of Opening Computers
This is the most common method, and usually requires the
removal of one or two screws.
Removing the entire casing:
This is common in older computers, and requires the removal
of between 3 and 6 screws.
Some flat footprint desktop models have buttons on the side
which, when pressed, release the case. The small Gateway Essential
computers of the last couple of years are opened in this manner.
Some unusual cases you
may come up on include the following:
Pull out chassis:
Some computers have a handle in the back, with which you pull the
entire chassis out of the case. Some older Compaq Presario's are opened
in this manner.
Screwed in at the bottom of the computer:
Some older Packard Bell computers actually have their side panels screwed
in at the bottom of the computer. You have to turn the machine upside
down, unscrew the panel, and remove it from the computer.
Growing in popularity and very good. The computer opens like a clamshell after pressing two buttons.
