Power led blink and the Mac won't start

Hi.

Some week ago, my Mac started facing the following problem.

When I try to turn it on the power led blink, but it doesn't start (nothing at all)

When I take the power cord out for a couple of hours and plug it again, the computer starts normal and can work for hours with no issue.

I’m guessing it the battery, power supply or the board if someone had seen this behavior and fixed it would appreciate any hints

I would start things off by running the onboard diagnostics to see what it pops for an error. Restart your system and press the ‘‘‘D’’’ key. Did you get anything?

You are likely hitting a low or dead PRAM battery. If you leave your system unplugged or use a anti-vampire power strip/surge suppressor you can encounter this. FYI: The PRAM battery is on the backside of the logic board

See the answer here for "Mac Mini won't turn on" answered on June 10, 2022. It's probably what you (and I) have.

Becareful! There are two versions of logic board here one with a discreet GPU and the other only offering the integrated Intel CPU graphics engine.
