Water damage, won't power up

My Macbook Pro got water damaged, while it was in my back pack... Water had entered in on the left side of the Macbook.

The Macbook was in a vertical position in my pack, with the left side where all of the port connectors are at the bottom of the pack, my water bottle had leaked some water and the nylon laptop sleeve absorbed some of the water.

Mistake 1) When I got home I didn't realized that the water bottle had leaked, and I tried to power on the Macbook... When I pressed the power button nothing happend, I had used it earlier at work and thought I had just closed the lid, and the macbook went to sleep, and ran the battery down.

Mistake 2) I connected the power adapter to the macbook. I realized I had a problem when the green led on the magsafe connector failed to light up as usual.

When i looked at the magsafe connector port i noticed a bit of moisture on the port and edge, felt the bottom of my pack and found it was real damp, and discoved the leaking water bottle.

What I'd like opinions on... Is there a way to test the individual components.. i.e. Logic board, Magsafe DC-in board, battery to isolate what part(s) shorted out.

I have a new MBP on the way, but would like to see if I can repair my old MBP to use as a back-up or maybe give to my nephew for school.

Thanks

I'd start with following the steps to really dry it out. Since it's not working pulling the DC-in board and going over it for damage would be a good first step after the rest of the machine is dry.

Once the RAM is dry and checked, and the battery is charged, & the DC-in board replaced you could try a boot (don't screw down the top case-just assemble enough to test). Depending upon what happens you may want/need to run your AHT (Apple Hardware Test) disk to see what else is/may be damaged.

Worst case - sell it as is, or part it out to recoup some of your loss.

dry it for starters. you want it completely dry! because the macbook laptops and most other laptop are scientifically modified for =these reasons= s4so, the dvd export, headphone jack, usb etc. are commonly and most likely he reason its not starting up. take a clean paper towel roll it up into a thin roll hold one end and ticck the other into each and every open air surface and gently move it around for about a minute. then make sure you laptop is charging open the dvd/cd part the hold down the own button. while pressing the on button on your mac hold down letter keys o' & m. after this if it doesnt turn on hold ctrl x and hope for the best

Same situation - on 2 different macs and this is what I did. Worked flawlessly. Hold down control option and shift on left side of keyboard for 10 seconds - while still pressing them press power button and hold all keys for 10 more seconds. Let them go then hold power button down for 10 seconds. White pole logo pops up with loading bar. And viola! When the Mac gets wet SMC freaks out so you have to reset. https://support.apple.com/en-us/HT201295

@Karla Bonilla thank you!

This worked on a Mac Air as well where battery was low, and computer was inside a bag that got soaked. Left it to dry for a day in a tray of rice and then applied the above sequence. Thanks a lot for the advice :-)

Currently in the same situation, my gf spilled water on the left side of my MacBook Pro mid 2012, and it looked like it was done on purpose as so much went in at a bad angle.

The laptop powered off, I turned it over, and took the back plate off and realised there was some water on the motherboard, and on the back of the laptop case (that I just took off). This happened last night. I just tried to turn it on, nothing, tried to charge it to see if the light came on, but no light.

going to leave it another 24 hours and hope for the best.

Any advice please let me know.
