try to are three times

or chaing mother board

1. for what you describe could be the sound card cable from the DVD or CD ROM
not sure without a physical look at the cable. there should be a black connector either at the
top corner of the mother board or by the pci slots that the connector is placed.
If you have a sound card mounted in a PCI slot then there is a connector on that board
for this cable.
I hope this helps. Have great day!

The info. you want is page 2-6. The bottom two pins on the diagram are for power on.

Start by trying another power outlet.

The power adapter should have its own light. If it doesn't light up then the adaper is bad. Kensington.com sells very inexpensive universal power adapters. You might also find a good deal on eBay.

If the adapter lights up then it may be your battery. Notebook batteries are only good for 2-3 years. If you let them sit for a long time without a charge they may only last 1-2 years.

Vote for this solution if it helps.

I've built a PC myself, each connector had text on it to say what it was and one arrow on it in relief, don't know wether that indicated plus or minus anymore.
Anyway, I recommend you just plug them in, and try to boot the PC. If it doesn't boot, switch the Power SW connector around, then it should boot. Do the same with the LED connectors, and it should work just fine!

Good luck,
Yannick.

i think this is enough which is given on the msi site itself contains all info about the connectors

IN order for the machine to power up properly. make sure you have correct memories specified by the motherboard manufacturer.
insert them as instrcited and connected a VGA (analog-old stype) monitor to the 15 pin connector. and power it up.
if it comes up great, continue with what ever you are going to do. if not, post back in this thread.

Sorry I lost my password. This is a common problem with the 610 and other laptops. This repair is not for a Novice. Please get the maintance manual from dell go to dell support its free and know the disassembly procedures for tearing your laptop apart. Remove the bezel on top of your keyboard. The start button is on a small pc board. The problem is on the connector on the bottom of this board that commects to the Mother board of your computer. Remove all external, and plug in devices to your laptop. including the battery. After removing the keyboard, the top plastic cover, the start pc board, ect. you can see the connector from the start board that connects to the mother board. Look carefully and gently see if this connector is loose. The mother board connector is supported by 2 silver looking braces on each end. gently see if they are loose. I bet that one end has broken loose from the mother board. re solder the loose end to the mother board. be careful not to damage anything as I said this is not for the novice. (with the laptop in pieces put the startup pc board back in, temporairly put the battery in and push the start button. If the led's glow, this is where the problem is. While your laptop is apart check for dust ect. You may need to remove the heat sink , and a back support brace to get to the mother board connector to re solder it.
This has been a problem on 3 of my friends laptops Pushing on a button harder and harder doesn't solve the problem. It's not the button .Now you know the rest of the story.
