Connect correctly Reset, power, and Led

It has been a lot easier to service desktop computers because some parts have been simplified, either by making them smaller or by putting them all together, like with hard drives or with all computers. One

It’s important to note that AllInOne type computers fall into the category of table devices. However, the process of making a repair or installing LED terminal wiring is very different from what you would do with a traditional computer.

There may be some brands that have changed how they install things, but most still follow the same standard. Keep in mind the following meanings of each switch so that you don’t get lost in the process of setting things up.

Power SW: You need to turn on the equipment to use it

Reset SW: It is used when the system has to be shut down or needs to be restarted.

Leds with +P and -P allow you to report the intensity of the leds at their highest and lowest points.

It tells you that the hard drive has been properly installed.

They all need to be connected because each one has a space in the socket. It’s important to note that each of them must be facing outwards and in the order shown in the following picture.

Keep in mind that the last socket does not have a coupling, so it must be left empty. I don’t why this is, but it doesn’t bother us to know either, the important thing is to connect the cables well and then turn on the computer.

If you did everything right, the computer should start up without any problems.

PC cases have a lot of wires and cords, but where do you connect them?

The first time you build a computer, you might not know where to connect all the cables that come with a computer box. If you have doubts and want to be sure, or if you just want to know what each one is for,

then we tell you where to connect all the cables and what each one does, so you can be sure that you are mounting your computer correctly.

When it comes to building a PC from scratch, everything can seem like a less complicated puzzle. However, it’s not hard at all and you just need to know the different cables and connectors on the motherboard and what they do, as well as how to use them.

To show you how to break down your computer, we’re going to show you how to do it in this article. You won’t have to spend a lot of time doing it, and you’ll also learn a little about the world around you.

Some boxes come with a lot of wires, and it’s sometimes hard to figure out where each one goes. This is a list of things that are called “front panel connectors.” In all but a few cases, they are always connected directly to the motherboard.

People who are building their own PCs for the first time can use this article as a guide. We are going to look at each one and explain what it does.

  • HDD LED – This connector goes to the hard drive activity LED. That little light, usually red, that almost all the boxes have on the front and that tells us that the hard drive is working.
  • P LED (+ and -) or POWER LED: these two connectors, which go separately, are the ones that give power to the equipment’s power light, which will indicate that it is turned on despite the redundancy.
  • RESET SW: it is the connector that enables the reset button of the box to work.
  • POWER SW: This connector, as its name suggests, is what makes the po button on the box work. In fact, if we bridge its two connectors on the board with screwdriver, we will turn on the equipment without the need for a button (if it is plugged in and connected, of course).

How to connect the cables on the front panel of the box

The first thing we need to do is find the part of the motherboard where the connection panel for these box cables is on, so we can plug them in. Almost always, it is in the lower right corner of the motherboard, close to the edge.

This is a general rule: Each connector has its name printed on it, and in some cases, the word “PANEL” is also printed on it, which makes it easy for you to tell which is which.

Make sure you know what the positive and negative cables are. If they aren’t marked, white is always negative and the other, no matter what colour it is, is always positive. Often, both of the cables are black.

The trick is to make sure that the area where the name of the connector is written always faces away from the motherboard.

Cables for the USB ports

The USB 2.0 cable (or cables, depending on how many USB ports there are on the front of the box) is also connected to the motherboard. It is used to make the front USB ports of the box work, in other words.

The cable is also connected to the motherboard. There are 9 pins on this connector, but the 10th isn’t there, which means we can only connect it in one direction. The connector itself always says “USB.” It’s the one on the left in the picture above, as shown.

Cable Connector USB Baseboard

The connector on the motherboard where we need to connect it is the same shape, but in male, it is usually screen-printed with USB910 or just USB. It is usually in the lower middle area of the motherboard.

At least two of these connectors should be on any ATX board, and each of them should be able to serve two USB ports on the front of the box. This is what is normal.

On the other hand, USB 3.0 cables are very long and wide, have 20 pins, and are usually blue. As a rule, they have thick and double cables (it is the one on the right of the image that we put before).

USB 3.X connector base board

As a general rule, these connect to connectors on the board called USB3. Usually, they’re found on the right edge, in the centre, and below the ATX connector, or in the lower centre area, near the USB 2.0 connector (or both).

In this case, you can only connect it in one direction. The male connector has a protrusion, and the female connector has a groove where the protrusion will fit.


Our computer is made up of electronic parts that, when they work, make a lot of heat that needs to be pushed outside. That’s why we need to have fans in our box, either to bring in much cooler air from outside, or to get rid of the hot air.

They give it the power it needs to move the fans, and in the case of a more advanced one, it will let us control how fast and how much air flow there is, as well as how loud our tower will be.

HD Audio

As a last step, we get to the HD Audio connector, which makes the 3.5 mm minijack for headphones and microphones that almost all boxes have. This connector is called the HD Audio connector.

Outwardly, it looks the same as USB 2.0, but the pin layout has changed. Instead of the tenth pin being blinded, the seventh pin is blinded, which makes it easy to tell because it’s marked “HD AUDIO” or “AC’97.”

The connector, as a general rule, will be right next to the USB 2.0, and it will usually be to the left of the USB 2.0. On some older boards, this connector was above the main PCI-Express port, but manufacturers realised that it was a pain to run a cable there, so they moved it.

We will be able to tell it apart because it has the name “AAFP” or “HD AUDIO” on it. USB 2.0 connectors don’t have a plastic cover around the pins. The pins are “in the air.”
