How 2 plug-in power button+LED, HDD LED & Speakers cables on HP DX5150MT motherboard

SOURCE: Front panel connections

Hi sjcrofts,
The most common problem for most people is knowing what wire color is positive & which wire color is negative. The colors blue, red, green, light blue, light red & light green are normally positive. The color white & black are negative. Your board uses only 2-pin connectors. The 3-pin power connector can be turned into a 2-pin connector to work with the M848ALU pins.
(Page 13, PANEL1). How to? Take the three pin connector, on the back side of the connector you'll see a small tab that holds the wire into the connector. Use a needle & pull tab up while pulling the wire out at the same time. The wire should slide out. Insert the wire back into the connector next to the other wire. You do not need to hook up the SUS led which stands for suspend.



Pin 1 is positive & the manual shows this by adding the _P = positive.
Pin 3 which is to the right of pin 1, is negative for the hard drive led. Pins 9 & 10 are not used.

Good luck sjcrofts!
Mike

OK, this is for all the idiots who reply and offer NOTHING. You need more info, model and ver? HE ALREADY GAVE ALL THAT INFO.
Type "M848A v5" in google and you will see it is a PCChips mobo AND the manual is here:
http://download.ecsusa.com/dlfilepcc/manual/848Av50.pdf
BUT the manual DOES NOT HAVE THE PIN-OUT, so the manual is worthless...
Here is the pin-out:
(2)(4)(6)(8)
(1)(3)(5)(7)(9)

...and thanks to guntotenmadm
"""Aug 28, 2009 - The pin layout on the MB are color coded. There is green, orange, pink, and blue. I'll start with the green pins 2 and 4 these are for the power led wires, bottom pin #2 is the + pin (your green wire). Pin #4 is - (your white wire). Now the orange pins, pins 1 and 3 these are for the HDD led. The bottom pin #1 is the HDD + pin (your red wire). Pin #3 is the HDD - (your white wire). Now the pink pins, 6 and 8 these are for the power switch. Pin #6 is the + pin (your orange wire). Pin #8 is the - pin (your white wire). Now the blue pins, 5 and 7 these are for the reset switch. Pin #5 is the - (your white wire). Pin #7 is the + (your blue wire)."""

i upgraded a friends pc and had the same issue but i solved it very simply see go out and buy a new case but before you do look at the floor model look at the connectors now most cases come with a atx universal plug it's something new i noticed and i just plugged in the plug now depending on the style you might have to reposition ( key it to the terminals) the plug to get the proper sequence but rest assure it is not that difficult did it to a friends dell and it works perfect no problems what so ever give it a try
