my mac book pro 2011 started having weird instances where it would just cut off and shut down immediately. Then when I tried powering it on, the indicator light would light up for 1 or 2 seconds before completely cutting off as if it were a power failure.
Sometimes I managed to boot it up again after waitint for awhile and I managed to do an aht test on it, revealing no problems with memory or the logic board.
What could be causing all this?
Edit: sometimes I get about 5 minutes of usage before it shuts down completely again.
Here's a video of how my mac is trying to boot up. https://youtu.be/wNEMUeyYfxY
