3115, magsafe led turns off after a few minutes

[Hardwood T/S]

So this guy had some ISL trouble, fixed er up and replaced the SDA resistor for the battery as well. Boots, detects battery and will charge it, but after a certain amount of time, the magsafe LED will just turn off and the machine won't take charge. Unplugging and plugging the magsafe back in from an outlet will cause the light to reappear and the computer to receive magsafe power again, and anywhere from a few mins/an hour the cycle will repeat. The magsafe will stay dark until you unplug/replug from wall, regardless of battery being connected or not.

Wtf is up? Tried two good magsafes and multiple outlets. Haven't tried another DC-IN board yet, wanted 2 get opinions first.

If no other DCIN board available, check continuity for central pin to U6900.
Some small resistor/coil should be in the middle.
Also check all traces from that small board.

Machine stays on in that moment?

Problem seems to have resolved itself for now, but given it's seemingly sporadic schedule of occurring I'll keep an eye on it and test what you mentioned if it happens again.
