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.
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.
To remove the chassis cover:
1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.
2Remove the thumbscrew or lock on the back of the case.
3With 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.)
