My macbook pro keeps having this issue of randomly cutting off and then booting back up after like 3 - 5 days like nothing happened. I fitted a new battery and didn’t fix the problemTried all key commands, PRAM, ect. You name it i’ve tried it, nothing has been successfulremoved the battery wait 30 seconds and plugged it back in and still didn’t workTried using just the magsafe connected without the battery to turn on and still didn’t worki’m not sure if it’s logic board issue but I’m not willing to pay £400 for new logic board and when i can just buy myself a new macbook. please can someone help me fix this issue so I can retrieve all my information from my MacBook Currently my macbook wont boot up and its been 3 days now and just need this sorting!

OK, let’s give this a try since you can’t get your system to start. Follow this guide to Step 6 MacBook Pro 13" Retina Display Early 2015 Battery Replacement with the battery disconnected with nothing plugged in to the external ports press the power button a good 15 secs. Now plug in the MagSafe with the battery disconnected does the system spontaneously boot up?
