How to connect power led ,HDD,Reset,power SW cables in hp motherboard s/n 383620-001

You should read the motherboard manual, for cabling:
1. Power SW
2. Reset SW
3. HDD led
4. Power led - and power led +
5. Speaker
Cabling scheme, also written on the motherboard.

If the Power SW not installed the switch on does not work.
If the Reset SW not installed the switch reset does not work
If the HDD led not installed the hard drive light (red) is not lit
If the Power led (+/-) not installed the power light (yellow) is not lit
If the Speakers are not installed, when the computer is on the beep sound is not heard.

I hope this information helps.

> HDD LED == hard-disk drive Light Emitting Diode (a "lamp" that lights-up when you are reading/writing files to/from your disk-drive)

> RST SW == the (optional) "reset" switch/button on the face-plate

> SPK == the internal PC loudspeaker

> PW SW == the power on/off switch/button on the face-plate

First, connect the "PWR SW", so that the ON/OFF button works.
It's much less important that the other wires be connected.
For example, if you never press the RESET button on the face-plate, you don't need to connect that button to the motherboard.

go to www.msi.com.tw for MSI guide , it should show you your motherboards front panel intel connection guide , it should be like this

PSWITCH PLED Open
RESET HDD SPK

hello, your front panel connectors like reset sw, power sw, hdd led, you can search easily. a use of screw driver touch all front panel connectors, if any response of connectors connect it.

Those are really tricky and always vary from motherboard to motherboard.
without the exact model no one will be able to tell you exactly. But I'd recommend that you start out with the power (pw) plug and try trial and error. The only ones really necessary are the pw and reset. the only 2 that are polarity sensitive are the HDD light and pw led.

Here is the Layout and installation of your board. Hope this helps.
