SOURCE: Led pins

I think you will have the an instruction manual of Packard Bell imedia 5106.In the manual an outline of the motherboard will be given.Figure out power and reset pins in the diagram given.

Usually the pins are at the corners only.
There will be labels near the pins like pwr rst etc.
Try connecting in the same configuration.

Please Rate me ;-) >Karatela

Hi 2VCRSDAD, no I do not think it's a power issue.
When a system starts but than shuts down before you can see any display or hear P.O.S.T. The problem is usually with a device connected to the board or the board. (Suggest you remove the memory & reseat. Making sure it is seated evenly.
Other simple suggestions. Did you check the CPU for bent pins before inserting into the socket? Did you place some thermal grease on the CPU before adding the heat sink & CPU fan assembly? Reset the cmos/bios page 18 in the manual.
Suggest you download the manual from Aopen, click on this link, for the English manual. (It takes a bit to open, wait for it).

The main site for the Aopen AX34-U is below.
When the above site opens, you will need to set the dropdown menus. "EX:" (Motherboard), (AX34-U). (Driver).

The Aopen AX34-U board does not have a power 4-pin_12v connector. There are a few settings that must be set directly on the board though. Some of these settings refer to the CPU, sound & front case connecters to name a few. The manual is setup nicely. You will find it to be very helpful.
Take you're time going through the manual & setting the motherboards settings. If you find you need help regarding a setting, feel free to post it here & I'll help.

Good Luck!

Problem with Auxiliary 4-pin pow er connector

Can you provide any specifics on the make, model, and what the power connector is labeled on the motherboard? We'll also need the make/model of power supply and the labeling on the physical connector that your using from the power supply (i.e. PCIe, or ATX, etc.)

No display ,no beep on motherboard

Try re-setting the ram and/or try different ram. Also make sure you have all the motherboard power wires connected, 20/24 pin main motherboard power, and the 4 pin cpu power (usually only if you have an Intel cpu). If that doesn't solve it, try another known working/new power supply.

Motherboard diagram Acer eMachine MB DA061/078L

Hello? Tap, tap on the monitor. What are you reading from?

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires go to from the Front panel, is the Front panel header.

Motherboard installed in computer, the Front panel header is at the Bottom/Right.
Two rows of 7 pins in a small black rectangular plastic block.

TOP row of pins is numbered EVEN.
BOTTOM row of pins is numbered ODD.

Starting on the LEFT side going towards the Right, TOP row:
Pins 2, 4, 6, 8, (NO 10), 12, and 14. Again, there is NO Pin 10.

Starting on the LEFT side going towards the Right, BOTTOM row;
Pins 1, 3, 5, 7, 9, 11, and 13.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

2) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

3) Pins 2 and 4 are for the Power On LED (Light)
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

4) Pins 6 and 8 are for the Power On switch.

5) The rest of the pins are N/C. Not Connected.

Don't forget to plug the 4-pin ATX +12 Volt power cable in,
(Top left corner),

I have disconnected all th ewire from my motherboard and i have installed all wire but unable to connect pw button,reset button,HDD led wire and anothed LED wire please tell me how can i install them in...

Locate the case connector pins on your motherboard. This will be a bank of two rows with 10-12 pins in each row. Each pin will be about 1 cm in length.2 Locate the power lead behind the power button on your computer case. The lead will consist of two thin wires, usually white and black, held together by a small plastic cap.3 Examine the underside of the power lead for an arrow or dot. If one is present, the marking signifies the first pin. This must correspond with the first pin on the motherboard, which will also be indicated by an arrow, dot, or number. If no markings are present, the lead can be installed in either orientation.4 Place the lead over the power pins within the pin bank. The correct pins will be indicated by a diagram on the motherboard, or by a picture in your motherboard's instruction manual.5 Connect the power cable to the back of your computer, and turn the computer on.

    I have got a system with an Aopen motherboard which having only a 20 pin connector for smps connectivity. the Atx smps i have is is 24 pinned. i can connect the main line by splitting up the 24pin...

    The actual Processor fan connects to the CPU Fan header on the mainboard. It's 4 small pins. It plugs in right near the CPU socket on the mainboard. Check the user manual for exact placement, you may download it from the AOpen website if you don't have one already.

    Plug in the 20Pin connector if that is the most Pins that the mainboard will allow. Cable tie the other 4Pins back onto the 20Pin connector.

    Then if there is additional 4Pin connector required by the mainboard for CPU power and you don't have that connector on you power supply, you will need to purchase a Molex to 4Pin CPU power connector. When you go to the computer store check with them that all is correctly connected.

    Take care!

    How do I find a manual for the ULT40278. I'm trying to figure out you would connect 2 fans when some motherboards have only one fan connection?

    Motherboard fan connectors typically use a small 3-pin which looks like this: zero_awake.jpg
    the left connector is a female connection (the side with 3 holes) the middle and right are male connections, has 3 metal pins:
    • Black: GND (ground)
    • Red: +12VDC or +5VDC (12V or 5V DC - direct current)
    • Yellow: Tachometer signal (used to read fan speeds)
    NOTE: Wire color may vary, and some fans or motherboards may control fan-speed.

    Some fans use a 4-pin connection, which is generally a CPU fan connector but not always:
    This pictures a 4-pin connection, but may look different from other 4-pin connections because the wires are covered in a black sleeve, which keeps them safe from harm and to reduce potential negative affects on airflow created when there are lots of loose wires inside a computer case.

    This photo shows a 4-pin connection attached to a motherboard next to a 3-pin connection in a motherboard. While it is not recommended in the case of the CPU's fan, in the case of other internal case fans with a 4-pin connection, it is possible to plug them into a 3-pin connector of the motherboard, but the ability to control fan speed, which is controlled in the 4th pin will be lost.

    Though sometimes computers have a way of controlling fan speed on a 3-pin or 4-pin connection even without the 4th pin, such *** voltage regulation and reading tach. feedback. These things are typically things a general user doesn't need to worry about unless their computer is running particularly hot and causing trouble.

    In which case, it might be worth investing some money in a fan controller, which takes a power connection, several fan connections (varies based on the controller you get) and gives you the ability to control fan speed externally on your computer case. My controller has nice dial knobs, though some "fancy" controllers have a display and up and down buttons. (Fan controllers would be at your own discretion in terms of price, you can get them cheap all the way up to seemingly ridiculous expensive)

    In the event of not having enough 3pin or 4pin connections on a motherboard, it is still possible to add case fans by way of 4pin molex connections:
    A female molex connection

    A male molex connection

    Some case fans run exclusively through these connectors, others have a combination of a 3pin (or 4pin possibly, though I've never seen this combination) and a 4pin molex connector. In this case, the molex connector can connect directly to a cord from the power supply and run the fan. It is possible to run case fans without having them connect to the motherboard at all! Which makes it possible to connect more fans, with less available connections for your fans on your motherboard.

    If a fan is a certain connection (any of the 3) and you need to convert it, for example:
    • a 3pin to a 4pin molex because your motherboard doesn't have enough 3pin connectors for all your fans,
    adapters are available to change one type of connection to another, at many online retailers (such as,, or other electronic supply retailers) and some retail stores, Best buy might have something, though you'd have a safer bet at a store like Micro Center which is more specialized for PC building or an alternative PC/electronic store.

    To ensure you solve your problem, just be sure to familiarize yourself with the motherboard you are planning on buying (or have) and the fans you plan to have inside your computer. It can be a bit more work to check the specs on the fans and motherboards, but a little work saves hours of headache later.

    Where does the power switch lead connect to an Asus A8000 motherboard?

    1 2 3 4 5
    6 7 8 9

    Usually the power switch connects to pins # 3 & 4 on my diagram above. You can test this out by shorting those two pins with a screwdriver and see if your computer powers up. If not, try shorting the other sets of pins, 1-2, 6-7, 8-9.

    Thanks and please remember to rate as fixya.
