DC in board testing?

Hi All!

I'm wondering if there's anyway i can test the DC in board to ensure its functioning properly?

I had a liquid spill and since then the light on the ac adaptor is dim and the OS reports "Not charging" - BUT, when left plugged in it does seem to trickle charge.

Edit:

I do get power to the board as it trickle charges. Runs fine from battery. The info i'm looking for is basically what lead on the board can i test for resistance and connectivety to ensure enough paower is pased to the logic board. Unit will NOT run without the battery...I'm assuming there isn't enough power to support the logic board on it's own.

Any direction would be appreciated.

Cheers!
