Practical - 78 :- Installing And Removing Of RAM , ROM

1. Objective

To demonstrate the correct technical procedure for:

• Installing and removing Desktop RAM (DIMM).

• Installing and removing Laptop RAM (SO-DIMM).

• Installing and removing Desktop Optical Drives (CD/DVD ROM).

2. Required Tools & Components

• Hardware: Desktop PC Chassis, Laptop, DDR RAM sticks, SO-DIMM RAM sticks, SATA CD/DVD ROM Drive.

• Tools: Phillips-head screwdriver, Antistatic wrist strap.

• Cables: SATA Data cable, SATA Power cable (from SMPS).

---

3. Safety Protocols (Mandatory)

• Power Off: Always shut down the system and unplug the power cord.

• ESD Protection: Wear an antistatic wrist strap or touch a grounded metal part of the chassis to discharge static electricity before touching any circuit boards.

• No Force: Never force a component. If it doesn't fit, check the alignment of the "Notch."

4. Practical Procedure

Task A: Desktop RAM (DIMM)

1. Opening Latches: Locate the DIMM slots next to the CPU. Push the plastic clips at either end of the slot downward.

2. Alignment: Align the Notch (the small gap) on the RAM stick with the ridge in the motherboard slot.

3. Installation: Push the stick straight down with even pressure on both ends until the clips snap back up and you hear a "click."

4. Removal: Press both side clips down simultaneously; the RAM stick will pop up for easy removal.

Task B: Laptop RAM (SO-DIMM)

1. Access: Remove the battery (if removable) and the bottom access panel.

2. Installation: Hold the RAM at a 45-degree angle. Align the notch and slide it into the slot.

3. Securing: Press the module down toward the motherboard until the side metal clips lock it flat.

4. Removal: Pull the two side clips outward. The RAM will automatically pop up at a 45-degree angle for you to pull out.

Task C: CD/DVD ROM Drive (Desktop)

1. Positioning: Remove the front plastic bezel/plate of a 5.25-inch drive bay. Slide the drive in from the front of the case.

2. Securing: Align the screw holes on the side of the drive with the chassis frame. Tighten the screws on both sides to prevent vibration.

3. Cabling: * Connect the SATA Data Cable from the drive to the Motherboard.

   • Connect the SATA Power Cable from the SMPS to the drive.

4. Removal: Unplug both cables, remove the side screws, and slide the drive out through the front.
