Water damage. To replace dc board or logic board?

I'm really hoping someone can help. Recap: small water spill. After upside down drying booted up fine but no wifi. Fine, bought wifi dongle and all good. Then couple weeks later, battery died. Replaced battery and all good. Then battery not recognized, an X thru battery icon and then computer only powers up with power button help down for several seconds then while power button pushed, plug in charger. Fan very loud. Brought it to Apple Store - told new logic board. Brought it too computer repair store, they never even booted it up and they said new logic board and MagSafe replacement. Computer wouldn't even power up using previously stated method. Took out logic board and cleaned well. After reinstall of logic board, computer powers up as previously described. Charging cord remains green, X through battery icon and no wifi except with dongle. Tried SMC and PRAM reset with no luck. Any help please? Possibly new MagSafe dc board or logo board.

Thanks for response. Will do. But it's a new battery.....ordered it of this website several weeks ago. Worked fine and then Mac says no battery (battery icon has X through it).

Update on original post:

Removed logic board and cleaned. Ran verify and repair disc permissions

Got newagsafe 60W power cord (previous cord was 45W)

Now mcp powers on with just power cord (light stays green), battery is recognized though won't charge over 1%.

Coconut battery findings says 19 life cycles and battery failure.

Amy suggestions now community is much appreciated!!!!

No need for a new logic board. Battery detection issues are usually the ISL6259 chip or the SMC. Both can be replaced by someone with the proper skills.

I recommend finding a repair shop that specializes in motherboard repair.

@tcrs_circuit is this the kind of thing you do? If not, do you know of a competent place that does it?

Let's look at the battery first. Download, run and report findings using Coconut Battery:

Says 0 for cycle count

MacOS battery status :unknown

NaN for both full charge and design capacity

Manufacture date: 1979-11-30 which is strange bc I just bought it 9-14-17

Age: 12,815 days

Battery failure: none

Power adapter: not connected (it is though green light has gone off. Mac doesn't run without being connected to power adapter.)

What do you make of coconut battery findings?

by

I think TCRS is correct.

But why would coconut battery come up with those readings?

by

Mayer - your business doesn't have any contact info listed...

I would like to contact you regarding repairs.
