MacBook Pro doesn't turn on after keyboard replacement

I recently replaced the keyboard on Macbook pro 13” (early 2013). After the replacement I tried to turn it on and on screen picture said the battery is discharged and that I need to charge it. When I plugged in the T shaped Magsafe adapter the light on it turned on green and Macbook still didn’t turn on or charge. After cleaning the charge port around pins and plugging it in again the light turned amber but there was still the same picture of battery being discharged. I also performed SMC reset when I got the charger working. I decided to leave it be and let it charge, so I didn’t turn it on. When I came back to the computer I saw that light on charger is turned off and when I tried to turn the macbook on nothing happened. And now I’m here writing this in hope someone knows the solution to my problem.
