Unhappy Asus ROG 751JT Power issues

Trying to find a schematic for a ASUS G751JT-WH71(WX).

Problems started with the laptop going from AC to battery and back again when playing games.
Eventually the battery would completely discharge and not even register the DC jack.
A few days would pass and it would work again.

Now there is NOTHING. No lights at all when plugged in. Power button does nothing.

What I've done/tried:
1. Replaced battery
2. Disassembled / reassembled many times ( pulled main / bios battery and held in pwr button for 1+ minutes)
3. Tested AC - DC power plug and can confirm 19v output (OK)
4. Tested for 19v at DC mini-board going into motherboard (OK)
5. No visabable shorts or suspicious items on motherboard. (OK)

It's 2yrs old, so no warranty stuff.

I was thinking it could be a blown charging circuit.

Anyone have any thoughts?

Thanks for any help you may have.

id say try it without the laptop battery in and see if it powers up then ?


if no go its likely the motherboard has gone bad and would either need repair or replacement
