Tip & How-To about Computers & Internet

How to ensure your motherboard stays longer.

Motherboard is the main part of your computer that contains all hardware components. Your computer motherboard could fry, if you do not keep it clean on periodically basis. Dust is the main cause to heat up your system and heat link to hardware failure. You can save your computer maintenance cost if you clean your computer on the regular basis. This will improve the cooling and performance of the motherboard components.

  • To clean your motherboard first unplug your system power from the electrical outlet.
  • Using the screwdriver remove the side covers of your computer case and put them to one side.
  • Check all data and power cables connections. Inspect all motherboard PCI and AGP slots.
  • Remove all add-on card of your motherboard for example RAM, modem, VGA, sound card and LAN card.
  • Now blow the air around all the motherboard sides and keeping away your blower nozzle 4 to 5 inches away from main board components. You can use vacuum cleaner also for this purpose but compressed air is the better solution to clean a system.
  • At the end assemble back all cards, cables and side covers of your system.
  • I recommend you doing this after every three months if you want to save your system life.

burnt connector inside dell inspiron, first connector at motherboard (after power box) Can I fix it?? If so, can u help??


LOVE your user name!

I'll try to guide you the best that I can.
Sorry, first connector after Power Supply does me no good.

Let's look at a basic schematic of the motherboard for a Dell Inspiron 530s Desktop PC,

Dell Support > Inspiron 530s Desktop PC > Dell Inspiron 530s Series Owners Manual,

http://support.dell.com/support/edocs/systems/insp530s/en/OM/HTML/index.htm

I would like you to click on - Removing and Installing Parts
In the left column click on - System Board Components
{System Board = Motherboard }

This is a basic view of the motherboard with No hardware components installed.
It is also how the motherboard sits in your computer.

This is a pictorial view of the motherboard,

http://www.amazon.com/Dell-Motherboard-Inspiron-Systems-Compatible/dp/B003CO0WQS

Now, compare the Dell Support motherboard illustration, to the pictorial.
Looking to the far right in the illustration, the first connector is marked with the number 8.

On the pictorial it is the rectangular Black connector at the bottom/middle. (Next to the rectangular White connector)

This connector is for a Floppy Drive.
Is this the connector in question?

Is it the white rectangular connector next to it?
This connector is for the main power cable coming from the Power Supply.
In the illustration is is marked by the number 7.

This is a basic example, of the power cable coming from the Power Supply (power box), that connects to the white connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

{Note* Color of the main power cable's connector does not matter. It can be any color }

IF this connector on the motherboard is burnt, you may wish to stop.
Electricity has more than likely fried the entire motherboard. May also include the Processor, Ram Memory, Harddrive, and a graphics card, if installed.

I know. I'm a 'ray of sunshine'.

How could this connector be burnt?
Four ways I know of;

1) Lightning storm, or power outage. Also could have happened if the power utility company was doing some changes in the power lines, utility pole transformer, etc.
(No. The utility company cannot be held responsible. I don't agree with that)

2) Power cable was not plugged in tightly. Lock on side was not locked into place.
Air gap created in-between the connecting contacts in the power cable connector, and the motherboard connector, created resistance.

Resistance creates heat. Burnt connector/s will result, and perhaps worse.
{Could also create a small power surge }

3) At one time Dell was a Proprietary computer manufacturer.
This means Dell wanted THEIR replacement parts used on THEIR computers.

If an aftermarket computer component is installed, Dell cannot warranty their computer.
Using THEIR parts in THEIR computers, Dell could.
However Dell computer users did not wish to pay the price of the Dell replacement parts.
The aftermarket parts were cheaper, of good quality, and readily available.

If we use a Power Supply for an example;

Dell had the motherboard manufacturer switch the socket holes around, in the Motherboard connector, for the main power cable.

They also had the Power Supply manufacturer switch the pins around, in the 24-pin ATX main power cable's connector, to match.

The aftermarket power supply manufacturer built the power cables, and connectors, to follow industry standards. Dell did not.

This means if you plug an aftermarket power supply's main power cable, into a Dell motherboard that was built proprietary, the motherboard usually fried. The only sign may be a burnt connector on the motherboard.

Could also have fried the Processor, Ram Memory, Harddrive, optical drive/s, and a graphics card, IF installed.

[ Looking at the Playtool link again, look at the photo to the far right.
See the different colored wires?
The color coding indicates what the wire carries as far as Voltage, or if it is a Ground wire.

1) Orange insulated wires = 3.3 Volts
2) Red wires = 5 Volts
3) Yellow wires = 12 Volts
(All are DC. In comparison two D cell flashlight batteries produce 3 Volts DC)

4) The Black wires are Ground wires

(The Green wire is the Soft Power On wire. Abbreviated as PS_ON)

The Orange, Red, and Yellow wires are power wires.
The Black wires are Ground wires.
Guess what happens if a 12 Volt wire is connected to a Ground?
(Instead of going to a 12 Volt connection)

Things start frying.

{To state connections in the main power cable connector, and it's respective connector on the motherboard, correctly;

Looking at the middle photo you see the connection end of the main power cable.
Plastic connector with individual plastic rectangular shapes, that have metal 'tubes' inside each of them.

The motherboard connector has socket holes to match the individual plastic rectangular shapes.
Inside the socket holes are metal pins. Contact pins.
The contact pins go inside the metal 'tubes'.

The metal 'tube' is a Molex Socket Terminal,

http://www.mouser.com/ProductDetail/Molex/36664-0002/?qs=sGAEpiMZZMvz8LftK4jerhl0r50z%252bUNRzFCdHbJqUTU%3d


4) IF the Power Supply, ( looking at it from the Back of the computer), has a rocker switch, or slide switch, to set the incoming AC power to 110 Volts, or 220 Volts;
And the power supply switch was set to 110, and plugged into 220 Volts,
the motherboard connector would fry.

Plus the Power Supply. May also of course include Processor, Ram Memory, Motherboard, Harddrive, optical drive/s, and graphics card IF installed.


Replace the connector? No
Could be;
A) Replace the Power Supply. Still no?
B) Replace the Motherboard. Still no?
C) Replace the Ram Memory. Still no?
D) Replace the Processor. Computer operates but no graphics?
E) Graphics card installed? Replace graphics card

Unless you can test each individual component, and the cost is not much less, or equal to a new computer, the obvious choice would be to purchase a new, or good used computer.

how to replace a powerjack


This is a difficult task, that only the most proficient tech should try to take on.
There are very fewer, and fewer techs that do this.
Why?
Because it is easier, and sometimes wiser, to just replace the motherboard.
[Also generates more money for a repair shop $$$$. There ARE instances when it is necessary to replace the motherboard though, instead of just the DC Power Jack. Read on]

That said, read the following, and see if this task is within what you want to take on.

1.Basic static precautions should be observed. The tech must wear an ESD wrist device to help prevent static electricity shock, to the delicate computer hardware components. Your body carries static, and body movements can generate Static.
Static can silently fry out delicate computer hardware components, and 9 times out of 10, you won't see it or feel it.

[A cheap ESD wrist device can be purchased for around $6 to $8]
The Electro Static Discharge wrist device has a cord attached to it, with an alligator clip on the end of the cord. The alligator clip is attached to a good ground source. (I use an empty desktop computer case, and attach the clip to the metal frame)

You should work on a tabletop, and wood, or fake wood is preferred. DO NOT work on a bed, couch, or directly on a carpet floor. These are high areas of Static electricity!

2.AC adapter, (Charger), and battery removed, the entire laptop has to disassembled, down to the bare motherboard in your hand. No processor, Cooling Tube and heatsink, ram memory, wireless adapter card, harddrive, optical drive, Nada. [The LCD screen is removed from the main body, and is not disassembled any further]

3.After THE correct DC Power Jack is located and purchased, then it's time to use the proper tools for removing the DC Power Jack. It's best to use a Soldering Station, but if you are proficient at de-soldering, and soldering precise electronic components, you can use a pencil tip 40 Watt iron. I recommend using Desoldering Braid, instead of using a Desoldering tool. Much easier, and a better tool.

I don't know your electronic repair expertise, but be aware that lingering too long when melting solder to remove it with the solder wick, (Desoldering Braid), can result in burning the motherboard, rendering it useless. Not enough heat when soldering, can result in a 'Cold Solder Joint'.

I pull up on the DC Power Jack to be removed with my fingers, as I'm melting the solder joint for one lead. Use finesse with the amount of force you apply, as you can apply too much force, and pull up a circuit trace right off of the motherboard! As the solder joint melts for that lead, only pull it up so far. Now go to another lead, melt the solder, and pull it out so far. Keep going around the leads until lead, by lead, comes out of the motherboard, and the DC Power Jack is in your hand.

I clean the DC Power Jack area on the motherboard with Isopropyl alcohol. Isopropyl alcohol is VERY FLAMMABLE, and should be used with Extreme caution! Keep the soldering iron far away from it, use in a Well ventilated area.
You want those mounting holes very clean, for the Rosin core solder to stick to it. I make sure the small area around each mounting hole, is tinned well with fresh solder. Gives a good area for solder to stick to, after the new DC Power Jack is installed. After the new DC Power Jack is installed, you may have to clip the leads that stick out, IF, they protrude too far. I haven't found any yet, but there is always the first time.

4.Now reassemble the hardware components back onto the motherboard, and reassemble the laptop.

If you have made a mistake anywhere along the way, you now have an expensive doorstop.

Some laptop motherboards have an area that the DC Power Jack mounts to, that resembles a Peninsula. (Like an island attached to the main body of land)

This Peninsula can break away from the main body of the motherboard. When it does, the circuit traces on the motherboard stretch, then break. (Circuit Trace. Think - Very, Flat, Thin copper wires)

Replacing the motherboard is the best option in this case.

Yes, you ->Should.
It looks like it is just a matter of making sure the cables are correctly connected, and the motherboard is mounted correctly.

(If there are fiber washers on the standoffs, Make Sure, you use them again! Rule of thumb is that if the motherboard mounting hole has a metal ring around it, no fiber washer is used. Bare motherboard mounting hole? Fiber washer)

However if this is a type of warranty work, the technician is fully responsible, should the installed motherboard be bad, or a mistake made when installing.

Every component installed on the motherboard, and to include the motherboard itself, is susceptible to static shock. Static electricity will fry out that delicate computer hardware, in a New York minute! You won't see it or feel it. Your body always carries static.

The processor is the main susceptible hardware component to static. NO mistakes can be made here!
Plus the top of the processor case, and the bottom of the heatsink, must be cleaned, (And done right), of thermal paste, and new thermal paste applied.
(If a thermal pad is used instead, they will probably apply a new one, but thermal pads are JUNK! Thermal paste should be used instead)

It doesn't take a rocket scientist to build a computer, or replace a motherboard. It does take certain criteria to follow, though.

Again, if this motherboard replacement is from the computer manufacturer, they will deem using a computer technician. (To back any future warranty, to solve any problems on the spot with the hardware, and to have a licensed person to drop the responsibility on)

I do not have enough knowledge about computer mnotherboard. What is its part and its uses and also what do thjey called as.


The motherboard is the most essential component in a computer. it is the piece of hardware which contains the computer's micro-processing chip and everything attached to it is vital to making the computer run.

The most important thing to remember about the motherboard is that it is a printed circuit board which provides all the connections, pathways and "lines" connecting the different components of the computer to each other - specifically, the Central Processing Unit or CPU, which is where (as its name implies) all the "processing" is going on to everything else.
