List the guidelines you should follow when you need to dissemble a computer, mobile device, or peripheral device for troubleshooting and repair.

Answer 1

Disassembling a computer or mobile device for repair

Step 1: Disconnect the power cord

The separation of externally linked devices is the first step in disassembling the computer system. Check to see if the computer system is turned off; if it isn't, shut it down and begin removing the external devices from the computer system.

Remove the Cover in Step 2

Unscrewing the screws on the rear of the case, sliding the cover back about an inch, and lifting it off used to be the conventional method of removing tower cases. To complete the work, screwdrivers of the appropriate type are required.

Remove the Adapter Cards in Step 3

Check for any cables or wires that may be connected to the card and decide if it is easier to remove them before or after you remove the card. Remove any screws that are holding the card in place. To release the card, grab it by the edges, front and back, and gently rock it lengthwise.

Step 4: Disconnect the Hard Drives

It is simpler to remove drives. Your computer system may have three sorts of drives: hard disk drive, CD/DVD/Blu-ray drives, and floppy disk drives.

Remove the Memory Module in Step 5

Memory modules are installed on the motherboard as chips, which might be damaged by incorrect human force.

Step 6: Disconnect the power supply

At the upper back end of the tower, the power supply is connected to the tower cabinet. Make sure the power connector from the switchboard is disconnected.

Step 7: Take the Motherboard out.

Before you remove all of the connectors from the motherboard, make sure you memorize them so you can reassemble the computer if necessary.
