Hello my humble followers is here again with another responsible post on technology tips  for you guys(computer hardware components).
Here are some briefly explanationor briefly explained step’s on how to assembling and disassembling a computer system.
So let sit back and follow up and read/study the step gradually carefully, hope we should be able to achievefrom our(alitech) article . Not to talk much LET GO strength to the point but before we go you may

OBJECTIVES

  • Disassemble the PC desktop/tower Computer System
  •  Identification of various composite components
  • Verify the correct interface cable
  •  Assemble the PC desktop/tower Computer System
  •  Boot up the System

RESOURCES

  • Quality screwdriver, Tester, Soldering Iron,
  • Desktop/tower Computer System
  • Operating system Windows XP or higher version installed
  • Utility programs
  • Multimeter or AVO meter for measuring Ampere,Voltage and Ohmeter

DISCUSSION

You must start the computer to verify that it is working properly. Then Disassemble and Assemble the PC. You will go through ALL the steps of disassembling except actually taking out the drives and the Motherboard out of the system unit.

PROCEDURE (COMPUTER SYSTEM)

NOTE: Computer disassembly is now complete. Now let’s start to reassemble back the computer

8. Connecting the front panel connection (ASSEMBLING AND DISASSEMBLING of computer)

(a) Find the power LED connector and connect it to the motherboard where it is – labeled Power LED. Go to Table 1-2 if needed

(b) Find the reset switch connector and connect it to the motherboard.

(c) Find the power switch connector and connect it to the motherboard

(d) Find the hard-disk LED channel 1 connector and connect it to the motherboard

(e) Find the hard-disk LED channel 2 connector and connect it to the motherboard

(f) Find the speaker connector and connect it to the motherboard

9. Install the adapter cards

NOTE: Always make sure the cards are lined up properly with the slots. It will require a firm push to get the card to reseat on the motherboard expansion slot

(a) Install the video card into the slot recorded in Table 1-1 and screw it into the back panel

(b) Install the modem card into the slot recorded in Table 1-1 and screw it into the back panel

(c) Install the network card into the slot recorded in Table 1-1 and screw it into the back panel

10. Connect the Power Supply (ASSEMBLING AND DISASSEMBLING of computer)

NOTE: All the connectors are keyed to plug only in one way

(e) Plug the ATX or AT power connector into the motherboard

(f) Plug the power connector into the floppy disk drive
