A power supply tester is a specialized tool that applies a load to all the output voltages of a power supply to check its proper functioning.
It's a must-have for computer-repair technicians, and a "nice-to-have" for hobbyist computer builders. Logic Probe. A logic probe is a tool used to check the operation and logical states of binary circuits.
It's most often used for differential diagnosis of problems that could be due to various components for example, is the RAM failing or is the chipset defective. It's an utterly useless tool unless you know enough about computer electronics to understand how to use it, and an indispensable one if you do.
Soldering Iron. A precision soldering iron is one of those tools that is rarely used in computer-repair work, but which has no substitute when you do need one. In computer-repair work, they're most often used to replace burnt-out capacitors on motherboards as a last-ditch effort to avoid having to replace the mobo. Networking Tools. Every computer technician and network technician needs a networking tool kit to make or test network cables or troubleshoot network flaws.
For hobbyists, it's more of a "cool-to-have" kind of thing. Hard Drive Duplicator. A hard drive duplicator duplicates hard drives. Some things just make sense. Computer technicians use hard drive duplicators all the time. Hobbyists probably don't need one unless they're really into the hobby. Copyright , , , , , , All rights reserved.
My motherboard is fried, but I will remove it anyway. The motherboard links every component in the computer together. The CPU, RAM, and expansion cards are attached directly to it, and every other part of the computer is in one way or another attached to it. The motherboard has seven screws holding it to the frame, which are indicated by large white circles around them. Remove those seven, then lift the motherboard out of the frame. Tip 1 year ago on Step 1. Get an ESD strap and greatly reduce your chance of electrostatic discharge frying something else you don't want to be forced to replace.
After unplugging all the cables - before you get into the case - push and hold the power button for up to 10 seconds to expel any remaining charge in the power supply. There can be enough residual electricity left in the power supply to kill a person if you touch it wrong.
AFTER doing this you can get into the case safely. The exception is if you haven't used the computer in a long time as the energy will naturally dissipate on its own, given enough time. Also, most things you take screws out of prefer to have those same screws used to put it back into whatever you're replacing. So it's a good idea to use some type of small containers with a note for each that tells you which component the screws belong to.
I've seen some people take notes on a note pad and literally tape the appropriate screws to each item's note. Tip 2 years ago on Step 5. Here's a good overview, it's pretty simple! Basically, keep things dry and well wrapped, and make sure anything that could be damaged by electrostatic discharge is stored in an anti-static bag. This was extremely helpful. If you are deconstructing a computer, it's useful to go by.
Question 2 years ago on Step Best Answer 2 years ago. I have a question. Is it possible to dismantle my current tower and throw it in a new case for the sake of saving space? My desktop tower is huuuge and i kinda wanna streamline everything. Reply 4 years ago. The case for a computer is not needed actually, as long as you have all the parts. You can even put it in a milk carton if it fits. But there lies the problem in getting a new case, size.
As long as all the the internals fit, and preferably have holes in the case for outside access, it should be fine. Reply 12 years ago on Introduction. Nah, I got a new super computer. But, I used all of the parts from this computer, and hooked it up to another mainboard I have. Reply 5 years ago. Reply 7 years ago on Introduction. Run cpuz and put the memory tab, take a screenshot and upload it here, I want to see proof CPUZ, Here is the direct download link.
Introduction: How to Disassemble a Computer. By Arbitror Check out my blog! More by the author:. About: One of my favorite hobbies is dismantling electronics, then either combining them together to create something new, or adding components to make them better.
I also like gadgets, whether it's taking them apart… More About Arbitror ». The first thing you do, is unplug every cable that's plugged in to your computer. So pretty much just unplug every cable from your computer. The power supply manages all the power for the machine.
The power supply is a large metal box located at the upper-back part of the computer. The main power cord also plugs into the back of the power supply.
The power supply supplies power to every component in a computer, therefore it has the most wires out of every other component in the computer. The first thing I will do is unplug every wire coming from the power supply. Next, push the power supply from the outside, then lift it out. Expansion cards are like small upgrades to your computer. Expansion cards give a computer new capabilities, once installed. My computer came stock with a TV and Ethernet card. If you only have one, remove that one.
Answer Note: It is only necessary to complete this lab if the lab computers are already built. The goal of this lab is to have the components separated and ready for assembly in chapter 3, and for the students to demonstrate proper tool use. The students will also apply proper tool use in the chapter 3 labs, where they will assemble a computer. This lab does not include removing the motherboard, CPU, and cooling device from the computer due to the replacement cost of these items.
If possible, allow students to remove these components from spare or broken computers that are kept in the classroom for part identification and demonstration.
Turn off the power to the computer and disconnect the power cable from the wall and the power supply. Answer Note: Explain to each student or group of students how a particular case is opened. Many have a simple catch, the front panel must come off first, or they simply slide apart. Show them which screws are holding the power supply in place before they begin. Locate all the screws that secure the side panels to the back of the computer. Use the proper size and type of screwdriver to remove the side panel screws.
Do not remove the screws that secure the power supply to the case. Put all of these screws in one place, such as a compartment in the parts organizer or small cup.
Remove the side panels from the case. If you have a camera or smartphone, take a picture of the inside of the computer case to be used as a reference when reassembling the computer.
Note : Some manufacturers do not use screws to fasten components inside of the computer case. Some may use plastic or metal clips that fasten components to the computer chassis.
Be careful to remove only screws that are holding components in place, and not the screws that hold components together. A Phillips screwdriver and hex drivers are the most commonly used screwdrivers to remove case panels.
Answers may vary. Normally there are two screws for each panel on a mid-tower case. Put on an antistatic wrist strap. Connect one end of the conductor to the wrist strap.
Clip the other end of the conductor to an unpainted, metal part of the case. If you have an antistatic mat, place it on the work surface and put the computer case on top of it. Ground the antistatic mat to an unpainted, metal part of the case. Skip to content Last Updated on October 12, by Admin 1.
