Power problem Mac Book Pro 13" Late 2011

[Master of the wind]

Hello guys, I have a very odd problem.


I was changing my MBP 13" Late 2011 hard disk for another one bigger (750GB to 2TB), and as always I do something with my mac, I disconnected the battery.


When done, I connected the battery back, but the mac won't turn on, no matter what I do.

Also, if I connect the charger or the battery, one led from the battery indicator is stuck.

This is a photo of what I'm talking about:

Could this be the logic board mixed with some bad luck?


Best regards.

Do you get power if you disconnect the battery?
If not, yeah, bad luck.
You could do a close inspection of the battery connector, make sure there is no damage to the connector that could be fixed by replacing the battery.

I suspect that there is a surface-mount fuse blown on the logic board.
You will need to find a place that knows board-level troubleshooting and how to repair the logic board.
Or, simpler, replace the logic board.

If I connect the battery, or if I disconnect it and then plug the power connector does the same thing.


I guess that the logic board is dead then...

Hi guys.

I made another account because I forgot the password from the last one, and also forgot the mail account I used for registering it.

Also, sorry for posting on a thread that died very long ago.

A friend of mine that works doing maintenance and repairing MacBooks at his job, took the MacBook a few days ago. He found that the keyboard died, and that was the reason why it won't turn on (the power button is tied to the keyboard). Also, he found that the battery died, and a memory stick died too.

It appears that something bad related to power happened when connecting the battery back.

He replaced the keyboard and the battery, and I replaced the memory stick.

He told me that the battery indicator seems to be just malfunctioning to. Also told me that the indicator, also works as a battery sensor, so as it is broken, the MacBook can't detect the battery.

It works well, but as it think that there are no battery installed, the CPU don't go beyond 800 Mhz.

My doubt here is that I bought a new battery indicator for replacing, but it doesn't seems to work. Even if I press the button to see the leds, it does nothing.

The MagSafe is always green, the indicator don't show a thing when connecting it, and it all work slow.

A thing that it's strange to me, is that I don't have a battery icon with a cross in the top bar, and if I go to System preferences -> Energy saver, and check the box "Show battery status on menu bar", the icon appears for a fraction of second, and then disappears, as the box get checked for the same fraction of time and goes unchecked.

Tried NVRAM and SMC reset, but I did not change a thing.

Should I do something else as the battery and the sensor was changed?

Thank you in advance guys.

Best regards.
