Laptop motherboard Bad Reason

Notebook motherboard bad cause analysis:

(1) The jumper is plugged in incorrectly. Of the 5 jumpers to be plugged in, there are 2 (hard drive lights, reset lights) that have polarity, if this is reversed, will burn the motherboard or hardware.

(2) If not careful, when installed, some metal did not notice good, hanging on the motherboard, when the machine lit. The motherboard will be burnt out. Or the machine is running. Accidentally, put the water in (of course this is very unlikely).

(3) The filter capacitor is burnt out. Although only a capacitor, but the capacitor in the motherboard is mainly used to ensure the voltage and current stability (filter action). Let us not overlook it. Because we know what it does, it's conceivable that the capacitance affects the motherboard (voltage and current effects on the motherboard).

(4) In the previous PS, if you do not shut down the case, directly unplug the mouse or keyboard, the same will burn the motherboard. But now the new motherboard supports hot plug, so that's fine.

(5) The quality of the power supply must also be considered, if the voltage and current instability, the motherboard will be greatly affected. Directly causing the burn of the circuit.

(6) Too much dust or a short circuit caused by wet, causing the circuit, the motherboard may burn out. (Own things, to be more regular cleaning Oh!)

(7) Overclocking, if overclocking will also make the motherboard load increase, if, more than the limit, it will burn. But now the hardware development is quite fast, overclocking has become the past.

(8) There is a problem with the quality of the motherboard itself. that is powerless.

Additional Notebook Board Failure analysis:

1, the phenomenon of failure: Choose a good style with the background, press the key to take a photo when the white screen and prompted "Device initialization error"

Cause: The video card is not in contact with the motherboard or due to incorrect driver setup.

2, Failure phenomenon: When the camera can not see the characters in the shaking, you can see the selected image, but the software in the blue Bottom

Cause: Visual camera power cord or video line contact is bad.

3, Failure phenomenon: in the picture when a large area of photos, not normal display all photos.

Genesis: Press the key to determine the speed too fast when taking photos.

4, the phenomenon of failure: printed photos have no date and hair color is not normal.

Cause: Black nozzle plugging ink.

5, the phenomenon of failure: After the photo is printed out of the color is not normal appearance bias.

Cause: Printer Nozzle ink shortage

6, the phenomenon of failure: Photo After the picture is printed out image tilt.

Cause: The printer is not placed in the paper.

7, Failure phenomenon: The keyboard above the first row of "exit", "Transmission number", "rearrangement", "change the background" failure.

Genesis: The green key on the board and the red button below the signal line contact bad.

8, the phenomenon of failure: in the picture when there are horizontal lines on the screen scrolling up and down.

Cause: Video cable Connection or power transformer failure.

Solution: Reseat The video cable and check whether the power transformer is plugged in, such as the failure still exists to replace the video line.

9, failure phenomenon: After the photo is not normal to print, and prompt port error.

Cause: Printer port setup is wrong.

10, Failure phenomenon: Small keyboard can not be used, but the main keyboard normal

Cause: Keyboard Setup error.

11, Failure phenomenon: The printer continuously prints the same photo or press after printing no response.

Genesis: Too many print tasks are pressed.

12, Failure phenomenon: Press printing, photo paper does not enter the print slot, but the print head is performing a printing task

Genesis: There are too many ink in the print slot.

13, Failure phenomenon: the image of the shooting is not clear, but print out very normal

Cause: The display is subject to magnetic interference

15, failure phenomenon: The photo only print part, and then show the lack of paper and so on a few pieces of paper, before the other part of the print out

Genesis: This may be caused by a drive or hardware instability.
