Thank you for the trick!! Unplug the battery. Unplug the MagSafe power cable. Hold down the power button for about 10 seconds and continue to do that. While still holding the power button down, insert the MagSafe power cable and hold it for another 10 sec. And it started right up. I thought that was a crazy thing to do and how did anyone ever discover that it worked??? But it sur did the job on this laptop I managed to switched it on, where my user login logo appeared, but then a loading bar would appear and just freeze.

I can send you the picture of what it's showing me now. Been trying several tips but nothing is working. Remember the reason you wrote this article, and why I wasted my time reading it, was because my computer wasn't starting up. At all! I reinstalled the OS as a clean install over the top of an install from Time machine.
Problem is it won't wake properly from sleep. Sometimes I get the log in screen - where password is required - and having input the password the same screen the appears again, When I input password for the second time it then lets me in and generally gives me the pages left open when put into sleep mode. It's so frustrating and bizzare behaviour. Disk utility tells me there is nothing wrong Any thoughts welcome. I did the power cycle tip too and it worked. Mine is a vintage one already. I used to leave it on Sleep mode most of the time while connected on the charger.
I'm not sure if that was the reason why the second I open it, it won't boot successfully. I'm worried about the files I just transferred from my phone but thankfully it opened so I'll go ahead and retrieve them back for safety. Thanks again! I followed the power cycle reboot steps and got my mac to give me signs of life and then when it died in the middle of boot I restarted the process and plugged the battery in the middle because I only have a 60w power supply and needed an 85w.
I used the battery as a wattage boost in the middle and got my computer back up and running. Thanks for the guidance. My Mac Pro late , non removable battery behaves strangely.

The battery died while the laptop was left running and it wasn't powering bank on. None of the reset key combinations suggested would power it on. I then put it back to sleep by closing the lid and connecting the battery back in.
I indeed seem have an issue with the power button but as long as I maintain charge in the battery I don't have to use the power button, I can just easily continue to put it to sleep and waking it back up using just the lid. Oh and I can also restart without any problems. It's only when I let battery die, or shutdown, that I have to open laptop, disconnect the battery, and repeat the process.
