MacBook Pro A1706 - Will not turn on - Please help :(

Hello everyone,

My MacBook Pro will not turn on. Please help. I do not know if not using it since the end of November(fall 2020 finals) might be the reason for my misfortune. The new term has started, and I would like to get this thing fixed.

I appreciate any help you can provide.

Quick info -

1. never been dropped

2. no water contact

3. literally it has been in its case inside my padded backpack

I have done the following -

1. checked the power cord and adapter with another working laptop.

2. cleaned the four USB-c ports on.

3. tried all the different key combinations to reset the computer. (pram and SMC)

4. opened the case and disconnected the battery, and plugged it in again.

5. tried to use the power adapter while the battery was disconnected.
