Opening the case
To work on the internal components of the computer, you must open the
case, which has two removable parts:
■
A chassis cover, that surrounds the sides and top of the chassis
■
A front bezel (faceplate) that covers the front of the chassis
Because the components inside your computer are extremely sensitive to static
electricity, make sure to observe the precautions (see “Static electricity
precautions” on page 15) to avoid static electricity damage.
To remove the chassis cover:
1 Turn off the system and disconnect the power cord, modem cord (if
installed), and all external peripheral devices.
2 Remove the thumbscrew or lock on the back of the case.
3 With the front of the computer facing you, locate the latches at the rear
sides of the case and pull both latches out until they clear the chassis.)
Warning Avoid exposure to dangerous electrical voltages and
moving parts by turning off your computer and unplugging
the power cord and modem cable (if installed) before
removing the chassis cover.
