Power SW/LED, HDD LED connectors on an old motherboard
I have an old motherboard of Intel 850 chip, running Pentium4. Now I am
moving it to a new case, which has individual connectors for Power switch, power LED, harddrive LED, each has 2, 3, 2 pins respectively. The old motherboard only has a single connector of about 8 pin with 1 single pin purposely missing, aka something like (1111_111). The connector on the old case has a label of 'V-P4', and the motherboard does not have any specific labels on them. Since I don't have a manual and it is a Emachines motherboard from Liverpool, which I cannot google anything useful from web, so would anybody tell me typically how are those 7 pins correspond to the power SW/LED, hdd LED connectors? Thanks in advance. Yang |

Thanks in advance. Yang I can not but you should look very carefully on the motherboard because most vendors print a pin layout somewhere on the board or on the original case. The old e-machines were assembled from standard components so post the motherboard product id or serial numbers and vendor. Worse case the product id of the original Emachine. |

Yes, most motherboards have (hard to read, microscopic print) abbreviations of pin functions printed on the mainboard. For power switch, it might be labelled "pwr" or "pwr_sw" or something like that. The LED connectors don't really need to be connected. BUT, they should also be labelled, lso. -Dave |

This is micro board, so there is no layout on the board. There is a
very schematic diagram on the old case only showing where the IDE, PCI slots etc. are. This is a EMachines T4130, motherboard from Liverpool 307130.

Yes, some of them do have, but others don't. They only have a label
such as CN84, probably stands for connector number 84.

Well, I could find a small photo of the board and that it is/was a very expensive motherboard. Maybe you could trace the wires in the original case back to the switches. IMO you only need to connect reset and power because the rest are onboard components. |

Google - Liverpool System motherBoard or - Liverpool 307130 Bunch of sellors like http://www.partstore.com/sl/parts.pl...0&yaindex=true jaster wrote: Well, I could find a small photo of the board and that it is/was a very expensive motherboard.

Power SW/LED, HDD LED connectors on an old motherboard
Thank you so much. It is amazing that you can find such a website.
The second link gives me some idea of how to do it. Even though the manuals on the http://www.emachine-upgraders.info/ do not include Liverpool models, it is apparent that the manufacturer, Trigem, uses similar connectors for the front panel connectors. The exact pin to pin mapping is different from model to model, but I think the cable colors stand for the same function. Here is something that I summarize after reading couple of motherboard manuals along the line: Pins: 12345678 or 123456789 Power switch: Blue/Yellow Power LED: Green/White HDD LED: Red/Blank So I find connectors by reading cable colors of the old case. Now my power switch and power led are working, HDD led still does not work even after I switch the polarities. But anyway, it is already beyond my acceptance. Thank jaster again for the help.
