Unable to power up after it slept
Suspecting that it's either in deep sleep, faulty power button, or fault motherboard.
Last used watching YouTube and left unattended until it slept. I managed to wake it up briefly before the screen went black and have not be able to power up since then. MagSafe seem to intermittently work but should not be a battery power issue since this event took place with almost a full charge.
Tried resetting SMC and PRAM but to no avail. Wondering if it's just a component issue that can be replaced myself.
Part replaced successfully and was able to power up! As requested, here’s the screenshots.

However while I was typing my update here, the MagSafe light went off.
I tried another MagSafe charger (a fully functional MacBook’s charger that is borrowed) and it could charge! Plugging back my own charger, the MagSafe did not light up.
Here’s a screenshot of coconut battery after the last sentence above.
I also have a lot of static on the top case. So much that I am currently typing without my palms touching it. I wouldn’t be surprised if I let my mac sleep or shut down, it wouldn’t want to boot back up again…
