My MacBook wont turn on after battery damage

Hi, after 10 months of not using my macbook I decided to use it again and charge it, the next day after I charge it, the battery got swollen very bad it even knocked the touch pad out of its place, I took off the back cover and removed the battery, then I connected the power adaptor but the macbook didnt turn on, at 1st the light on the power adaptor was on but after a few tries it went off and never came back, now whenever I connect the power adaptor the only thing that turns on is the "battery indicator thingie" light, it flashes a few times when I press the button...

please help

Thank you

Unplug trashed battery. Hold power button down. Keep holding power button down. Then plug charger in, with power button held down. Does it turn on?

Measure voltage on PPBUS_G3H, PP3V42_G3H, PP5V_S5 and PP5V_S3 on your logic board. Red probe on point where voltage shows up, black probe on ground.

Then switch multimeter to diode mode. Red probe on ground, and black probe on the following points; measure SMBUS data line ends of R5280 & R5281 WITHOUT battery or charger plugged in, using diode Should be 0.435-0.461 on a non-&&^&@@ up board.

You will need a multimeter, schematic, and boardview for your specific logic board model number to begin this journey. If you are willing to follow along, I can help you troubleshoot the problem, learn something, and save a lot of money. If this seems like a nightmare, give up and buy a new machine.
