7.2. You Should Have Sufficient Space 

You need sufficient space to keep the PC casing, monitor, disassembled components, disassembly instruments etc. At least a large tabletop fully should be used for this purpose. If air conditioner is available, raise the air humidity to approximately 50%. 

7.3. Store All the Small Parts In a Safer Place 

Use a pot or bag to store the small components such as screws and small pieces of hardware. If these are just left on the table, then may fall down and you may lost them. 

7.4. Backup the CMOS Configurations 

All the modern personal computers store the important hardware information in a small chip call CMOS. If you disassemble the computer, the information stored in CMOS may be lost. Steps to write CMOS configuration: 

 Restart the computer 

 Press when a prompt like “Press Del to run CMOS” appears on the screen. 

 A menu specifying different CMOS properties will appear. Go to different options in the menu and write down the configurations stored there. 

 Using the menu option like “Exit without save”, exit from CMOS. 

7.5. Turn the PC and Associated Peripherals Off 

Before disassembling the PC and other peripherals should be turned off. Because if anybody touches inside the PC during its power is on then he may get shock.

7.6. Remove the Monitor from the PC Top

To open the desktop casings the monitor should be removed from the top and placed on the table. For tower casings it is not necessary.
