Why my MacBook doesn't detect MagSafe charger?

Hi,

i have a problem with my black 13" MacBook. Sometimes MacBook didn't detect MagSafe charger. I say didn't because it doesn't charge my MacBook now.

When i connected adapter to my laptop green led doesn't bright. Other times it charged, but now it can't. With the battery it works perfectly, but i don't have other MacBook to charge battery in it.

I try with other charger without results. I think it could be DC-IN or Logic Board. I try DC-IN with a multimeter, and pins one and five are connected, second and fourth also and the center pin it's not connected to other pins. Without battery laptop doesn't power-on, because charger isn't detected.

I would be very gratefully about any help.

Thanks

Regards

Pins 1 and 5 are grounds. Here's the pin out: http://en.wikipedia.org/wiki/MagSafe

Check the AC adapter to see if the pins are extending and if they are charged. If it's OK then I would replace the MagSafe port. Here's how to do that: MacBook Core 2 Duo Magsafe Board Replacement
