MacBook refuses to show any signs of charging or life.

Dear beloved iFixIt,

Statement of the Problem:

My Macbook unfortunately is not turning on, Not charging battery - only green light. Feels like a bricked device on my table here. No chimes, no lights, nothing seems to be working.

How it occurred:

On a very busy day, as I was about to leave home to another town, even though I had just 5% left, I forgot to shutdown my MacBook and closed the lid to deep sleep. 5 days later I reached home to obviously find the MacBook dead. Thinking this is just a battery-no-charge problem, I plugged in my device to find the MacBook not charging and not turning ON.

What I have done everything since:

I tried almost everything I could find in the internet regarding MacBooks not switching on. I did the SMC reset, I did various key combinations found online, I removed the back cover reset the Ram, disconnected and reconnected the battery, tried different chargers, replaced DC power jack board. Nothing seems to work.

Clarifications:

1. Absolutely no water damage
2. Airport card not working - I therefore disconnected the card permanently.. worked fine without it for almost 3 months.
3. Upgraded to 16gb Ram, 256Gb SSD and 1TB HDD about 1 year ago.. worked fine till recently.

I literally have a sitting INR 1.3 lakhs paper weight/brick infront of me.

Please help ..

Thank you so much in advance…

Your ideas will highly be appreciated…
