Types of Motherboard Connectors by Jason Artman The motherboard is the largest printed circuit board inside a computer case. All of the components in the computer connect in some way to the motherboard, and it serves as a sort of traffic controller for the data sent to and from the computer’s components. A motherboard has connectors for many different types of parts, and the layout of one can be daunting to a person examining the inside of her computer for the first time. The CPU socket supplies power to the processor and allows data to be sent to and from the processor from the computer’s memory. RAM acts as a high-speed system for temporarily storing the data needed by programs while they are running. When the processor needs instructions, it receives them from the RAM, and when you save a document or file, it goes from the RAM to the hard drive. Hard Drive Connectors Generally, a motherboard has at least two hard drive connectors. Current motherboards use Serial Advanced Technology Attachment SATA hard drive connectors, which have L-shaped curves to ensure that cables are connected in the correct direction.
Hooking up a motherboard
Step 17 – Troubleshooting How to Connect Computer Wires – Correctly Computer wiring includes the wires that you see connected to the front of your case, system fans, and miscellaneous motherboard connections. Let’s start with the case wires. First, identify the different cables that are attached to your case. These are usually bundled together near the bottom, and the computer connectors on the end of the wires are labeled.
Look on your motherboard for the front panel connection area. See label “M” on the motherboard diagram.
You’ve turned the front power switch on and off, and you’ve hit the reset button when your software hangs up. Well all that is controlled by the motherboard, the lights and switches on the front of the case are hooked to the motherboard through these wires.
Hi, I have unscrewed all of the screws and my beautiful laptop is now a mess. But to get to the connections, I need to take the main face plate off the one surrounding the mounse pad. But when I pull, it pulls off all around the edges like something attatched in the middle is holding it down. Dee April 8, my kid split coke at a few keys om the keyoard. April 11, Wow, this site is wonderful. I have what seems to be a unique issue that maybe someone can help with.
A while back my computer started looping between the start-up BIOS and the Vista loading screen when I would boot it up. Somehow or another I ended up at the recovery console and tried to reinstall windows I think the original problem was with the MBR, but learned of this too late. The reformat of the drive went through, but then the recovery console froze.

Contact Author Source Many RVs and camper trailers use a power converter to operate the lights, refrigerator, vent fans, and perhaps the thermostat on the heating system. The converter uses the volt AC power from the local power source and transforms it into the volt DC these items require. This article is intended to help you troubleshoot many converter problems and to repair or replace the unit if need be. Since there are different makes, types, and sizes of converters, this article will deal with problems common to most models.
Although electrical knowledge is helpful, it is not necessary in order to be able to check the power converter or to repair or replace it.
Oct 16, · I’m not sure where to hook up the Reset Switch wire and the H.D.D. wire. The Power LED had a label on the motherboard, and I’m assuming that the Reset Switch wire and the H.D.D. wire go right next to it on the available pins, but I’m not sure what pins to use, and the motherboard .
On the picture above you see some typical looking inverter boards found in laptop computers. The inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. The inverter board converts low voltage DC power few volts supplied by the motherboard to high voltage AC power few hundred volts needed for the backlight lamp. When the inverter board works properly, the backlight lamp gets power and the LCD screen lights up.
As a result, the image on the screen is bright. One side of the inverter board connects to the backlight lamp and another side to the video cable LCD screen cable. You can get an access to the inverter board when you remove the screen bezel — a plastic frame around the LCD screen. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable.
When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above.
SOLVED: My Toshiba laptop powers up, but the screen is black.
Release the retaining clip. If the slot has two clips, press both down simultaneously. Remove the left panel to open the main case compartment. Some cases have power supply cages on the bottom, and some on the top of the case. Secure it to the case with the screws that came with your power supply.
Hey, I’m new to the forums but fairly experienced when it comes to computers. I’ve got a Dell Dimension and a FP monitor. When i boot the computer up, the video card’s fan is spinning and the computer seems to power on fine except for the fact that there is no image on the monitor.
Thanks for the help and the link manojtk January 18, Great tutorial. I am a complete newbie wrt soldering and stuff, but I went ahead and bought all the equpiments suggested here for under 20 pounds, and it took me about six hours to dissemble the laptop again following the tutorial here, fix the soldering and put it back together.
Needless to say it worked!!! Btw few variations between the instructions here and what I did 1. Didnt remove the modem card 2. Didnt remove the CPU 3. So I just applied fresh solder on top of it. Thanks again for putting together this tutorial.
TRYING TO HOOK UP MU POWER BUTTON NEED TO KNOW
Important In order to use USB 3. Apu accelerated Processing Units This motherboard is designed to support overclocking. Before attempting to overclock, please make sure that all other system components can tolerate overclocking.
And now for a tip: if you hook up your power supply to the board and before you’ve even pressed the power button for the board, your supply is showing a current draw, then there’s a short somewhere on the vcc line for the motherboard.
It converts a couple of 4 pin peripheral power cables into an 8 pin 12 volt cable. If you use one of these adapters then be sure to plug the 4 pin peripheral connectors into separate cables coming from the power supply. If you plug them both into the same power supply cable then you are drawing all the power of the 8 pin 12 volt connector through a single 18 gauge wire.
You can often get away with that but there’s no reason to do it. If you leave the two pieces separate then you can plug one of the 4 pin pieces into a 4 pin 12 volt connector and leave the other 4 pin piece unplugged. If you look carefully at the image above then you can see the polarization of the pins which prevents you from plugging the cable in improperly.
Hooking up case fans into motherboard
On the top right of the board there is a standard CPU power connector and next to that a 4 pin power connector as well. My power supply does not have a supplemental 4 pin connector. Do I need this and what is this extra 4 port connector used for?
After that a different power jack has to be installed, attached to the case of the laptop and connected with wires to the motherboard, as the patched board wouldn’t be strong enough to support the original type of power jack that was soldered directly to the board.
Where to connect case’s power-on button? It is an Intel 02R I can’t figure out how to connect the case’s power button to it. So, mentally divide the pinout into quadrants and assume one of them will be the power. Then it’s just a matter of narrowing down the possible combinations. Try plugging in JUST the power switch in different locations until you find the position that lets you turn on the machine.
When you find it, leave it plugged, then fill in the other connections one at a time by trial-and-error from there you can’t hurt the machine this way. It should take you a max of nine tries to narrow down all the possible combinations.

The headers circled in red are four pin PWM headers, and the three headers circled in blue are four-pin PWM headers, but they can also work with 3-pin fans, however at default they are in PWM mode. I recommend using PWM fans with this motherboard. The motherboard’s aesthetic appeal has changed a lot. Its predecessor was of a black and green design and boasted a lot more angles. The back of the motherboard is pretty bare. The three x1 slots are routed to the PCH.
On an ATX-style power supply, there is no attached power supply; instead, a wire runs from the case’s on/off switch to pins on the motherboard, and when you press the power button, those pins.
If someone trips on the wire while you have the power adaptor plugged into your laptop, chances are that the power jack will get damaged. On most laptops the DC power jack is soldered directly to the motherboard and there are only three or four small pins holding it in place. Unfortunately that makes the power jack quite weak.
Any sideways pulling of the DC power cord while attached to the laptop will usually dislodge at least one of these pins, breaking the solder around it. Modern laptops use quite a lot of power, from about 70W to W or even more. The bad electrical connection from the dislodged pin will cause sparks and heating that will eventually burn a hole through the motherboard and can even be a fire hazard.
The usual signs of that are:

All tasks are undertaken on linoleum floor, after washing hands and using the static elec protective wrist band clamped to the PC Case metal. Unhooked all power cables. Pressed the CMOS clear button. Connected a mouse, keyboard, and monitor. Plugged in all power connectors. Turned on the switch on the back of the PC.
No Display, No Beeps on start up.. you will need to hook up a motherboard speaker to hear any post fault code. Just touch a metal item to both power button pins to try to power the.
I think you are probably right. The powersupply is a Bestec W unit. I have replaced it, but the green light on the mobo is all I can get. I was not aware of the issues with that power supply. There is a diode mounted on a two pin post labeled “Thermal” on the mobo. Never seen one like it before. Do you think it might be some kind of thermal protection device? Went onto the Intel site but no response as yet.
It is an Intel GCZ board but nothing in their support manual ever mentions it either. I tested it with my ohm meter and it shows as open in both directions. Probably nothing but just thought I would check. Good little machine, although now a bit dated. Most motherboards have those to dynamically adjust fan speeds. Most motherboards can be set to sound an alarm or shut down when the CPU reaches a certain temperature, but I don’t think the motherboard sensors do that.
