Chosen Solution

My macbook pro started randomly turning off. Eventually, it would not get past the turning on screen. Did an SMC reset and it seemed to work again for a day. Then it just wouldnt turn on at all. The power charger light is orange and it turns green if i try a smc reset. I took it to an authorised service center. They said there was “damage on the capacitors on the logic board responsible for power.” I was quoted $650 for repair which involved a new logic board. Seems a bit excessive for a 5 y/o laptop. Is there anyway I can just replace the capacitors?

Sounds like someone is trying to sell you an overpriced board replacement. If you want to have someone taking care of your Mac, a typical board level repair would be in the range of 200/400$..if you want to invest a few hours time you can buy the board and replace it yourself, there are many sources around including iFixit: https://www.ifixit.com/Store/Mac/MacBook

Although what they described isn’t technically impossible. I have serious doubts that a capacitor is/was intermittently shorting and turning off your system. Assuming it is just a capacitor it is absolutely possible to change. I would need more details about the system to make a more informed decision.
