Hi,

I've a MBP 2009. With time, I have more and more difficulties to start the computer. When the computer is "cold" (no boot for some hours) and you press the power button, it tries to start (2-3secs), and then shut off. So I restart, again, again and again. With tries, it shut off later. Finally, I'm able to reach login screen. Then the computer is stable and I've no more shut off. I can keep it running during 24 hours without issues.

It's like the issue is happening when the computer is not "hot" or needs energy.

Thanks

It looks like the battery is fine ?

Thanks @mayer. I replaced the battery with a new "genuine" one. Unfortunately, it doesn't solve the issue. It is still exactly the same. I'm also surprised that even with a new battery, if I unplug the magsafe, the computer shutdowns 2 or 3 seconds after that.

I'm now wondering if it's not an IC issue related to power on the logic board. Maybe you have some more hints ?
