Pinout for pwr sw - eMachines ET1161-07 Desktop PC

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.

You pretty much need a flashlight and a magnifying glass to have a look see at the header on the motherboard. The pinout is printed on the board in _very_ small print. The LED's are the only ones that require polarity to work. Connecting the wires wrong won't hurt anything...it just won't work the way it is supposed too. A little trial and error may be in order.
Another, more accurate solution, is to go the manufacturer's website for that computer and download the user manual. The pinout will be in the manual, usually under "front panel connections".

Here is the pinout. Note key pin 2 missing.

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!!

Here is the pinout for several Intel MB's with 845GV Chipset.

You can download the complete user manual in English from the manufacturer's website at this link:)

The front panel connector pinout is on page 2-33, or page 59 in the PDF file. You should have mor ethan enough information to make all the connections you need.

You don't say what case you are using. If it is proprietary and the front panel header is all in one connector, you can carefully back the connector pins out of the block using precision screwdrivers. I keep a bunch of two pin connectors from junked machines so I can create individual connector sets when changing motherboards (eg, PWR SW, PWR LED, HDD LED and RESET). This also requires that you know the pinouts of both the old board and the new one so you can get everything connected properly.

Very doubtful you will ever find an adapter to change from one front panel block to another.

The 9-pin connector probably uses a spacer pin between the legs of the PWR LED, while it seems the 6-pin does not have RESET.

Hi bwalker24,
This is a pic of how to connect you're LED & switches.
Enjoy!
