Problem with the MSI 7050 v2.0 (HP dx5150) Motherboard Front panel wiring colour diagram please.... PWR LED, HDD LED, PWR SW, AND RST SW

I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

LED stays on? You have the Power On LED (Light) pins.
LED blinks? HarDDrive activity LED (light) pins.
Computer restarts? Reset switch pins.

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

Most of the wires on the front panel are just for LED Lights other than the Power Button. Look on the motherboard for the abbreviated spellings of PWR for the Power Button, RST for Reset, HDD for Hard Drive, etc. Only the PWR will keep your system from booting up. If you place the others on the wrong set of pins the Led light will not illuminate.

Hi scouts692

The Front Panel Header Pin arrangement for this motherboard is unusual, in that the header only appears to have 8 pins in a single column rather 2 parallel columns of 6 Pins with 1 blank, as most conventional motherboards do.

Pin 1 is POWER SWITCH orange or red (PWR SW 1)
Pin 2 is POWER SWITCH white or black (PWR SW 2)
Pin 3 is POWER LAD + (PWR LED -)
Pin 4 is POWER LED - (PWR LED +)
Pin 5 is HARD DRIVE LED - (HD LED -)
Pin 6 is HARD DRIVE LED + (HD LED +)
Pin 7 is RESET SWITCH blue or green (RST SW/RST 1)
Pin 8 is RESET SWITCH white or black (RST SW/RST 2)

Please refer to a PDF of the Motherboard Manual for additional information about the setup of this motherboard (the relevant page for the Front Panel Header is page 17/Section 2-13)

hope this helps.

Sorry, I can't find a color diagram. But check page 2 of the HP support manual, this shows all the jumpers and board connectors. You can download the manual from the link below:

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c00358730/c00358730.pdf

Connect the front panel leads to the motherboard connector marked "JFP1" using the following pins as indicated by the markings on the motherboard and the front panel leads: HDD LED on Pins 1 and 3; power LED on Pins 2 and 4; reset switch on Pins 5 and 7; and the power switch on Pins 6 and 8.

Good luck.

Pin outs for MS7050 v2.0 HP DX5150 are as follows.

looking from edge of board L to R

First edge pair HDD LED + - First inner pair PWR LED + -
Second edge pair RST SW Second inner pair PWR SW

there is no need for the wiring diagram
if you check *********** board properly
you could find written in small font like
PWR SW for power switch
RST SW for rese switch
HDD LED , PWR LED etc

It is silkscreened on the moterboard at the bank of pins for the switches and lights. it is usuall abreviated as PWR SW, RST SW, HD LED, SPKR, PWR LED, ...If it is not silkscreened then look at the manual on the manufactures website. they will have a photo of the MB with it illistrated. go to

Hi there
The front panel connectors are mainly,

• harddisk activity connector
• power switch connector
• reset switch connector
• power LED connector
• speakers connector
• USB connector

Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

Good luck and thanks for using FixYa!!

PWR > PWR (aka PWR SW), HDD LED > HDD LED, RST > RST (aka RST SW and Reset)
