Connection pins of RESET_SW, POWER_SW, etc

[Ashutosh32]

A friend accidentally pulled out the various chassis based switch connection pins of switches and LEDs from his motherboard. His motherboard is manufactured by HIS, an abhorred company which doesn't seem to have a website. He brought his system from a local dealer (these people buy out stuff and do the custom building job for us) and the dealer did not supply the manual for the motherboard. How will he put those pins back in place?

Three steps to heaven...

1. Google "HIS motherboards". Notice http://www.hisdigital.com

2. Contact Us... email... PDF manual please

3. Hooray!

Or... simply ask the dealer for the manual. Or ask the employee who assembles them to draw a diagram on a piece of paper. Or study a similar computer.

for (1) : We found this site on IRC Chat. We ruled it out because there was no mention of motherboards. Also, the logo is different. Not the HIS I need.
the dealer refuses manual saying that it will void our warranty for the product.

Dealer understands that foolish meddling has already taken place. Pay dealer to repair computer damaged by user foolishness. Learn lesson.

If there's a more helpful advice, welcome!

You can view a lot of different ways basing on your mobo for the connecting pins, certain diagrams will give you idea on how it should be, just like this one : http://k7s5amotherboardforum.yuku.com/forum/viewtopic/id/2034

I've yet to encounter a machine that doesn't silk-screen label the front panel connector block to indicate what goes where. Some people might get confused about the direction to plug it in; remember: "the red wire always connects to pin one" (that would make a great bumper sticker...) Of course, they don't always have a red wire. the black wire(GND) is generally on the opposite side to any notch or other marking on the motherboard header.

A "1" might be silkscreened (printed) next to Pin-1 and/or the solder pad might be square instead of round.  Odd numbered pins are on one side, evens on the other.  As BC said, it's always silk-screened on the board.  Polarity is not an issue with the PWR SW and the RST SW.  If you reverse any of the others, it will do no damage, the indicator light won't work.

You can do it by trial and error.

1. Disconnect the AC power lead.
2. Identify which lead goes to power button.
3. Plug this lead (only) into any position on the header.
4. Connect AC power.
5. Press power button.
6. If computer powers up, you have found the right position.
7. If it does not, try next position. Eventually you will find the right position.
8. Identify lead for reset button.
9. Plug into any one of remaining positions.
10. Power up PC. Press reset button.
11. If computer reboots, you have found correct position. If not, try other positions, disconnecting AC before moving connector.
12. When you have found these two, you will probably have HDD activity light and power light leads left.
13. Identify correct header by similar process. Observe flickering light when HDD is active.
14. Remove AC power while connecting & disconnecting leads.

Some connectors are polarised. (can only connect one way)

Not these.

[Salmon Trout]

Not these.

Agreed. To the OP... get the power and reset buttons right before you try the LEDs.

Finding the pwer pins is easy. Get a long screwdriver and run it allong the pins. Whilst the machine is off only power will got to the power switch live pin.

You do this at a slight  risk but I have done it many a time on archaic systems to ressurect them where no documentation can be found.
