I have a MacBook Pro 15” Unibody early 2011. After leaving the device unused and uncharged for 2-3 weeks it booted okay, but failed to detect the magsafe.. the light was off and it failed to charge. So, I found a technique online that has worked on a number of occasions… I don’t know if it’s a good practice, but it does work… at least for me.
 
* Disconnect Magsafe
* Open case and disconnet battery with a spudger or carefully with a fingernail.
* With laptop facing bottom-up with the cover off, reconnect the Magsafe.
* Wait patiently, and the computer will (hopefully) boot itself without the need to press any buttons, it can take a minute or two, so be patient.
* Just after the unit begins to reboot itself, quickly smack in the battery connetor and seat it firmly.
* Hopefully your magsafe light will come on, pehaps first green for a moment, but then changing to orange.
This method is only known by some people, but not too many. The point is, that after applying magsafe power, the unit will automatically reboot itself, but this can take quite a while (maybe a minute or more), but the bluish/white “on” indicatior light (normally on the front right, but now on the right rear seen from inside) will light briefly, and then go off again. Then it will light up again as the disk and fans starts turning. It’s important to reconnect the battery quickly just after the “on” light comes on the FIRST TIME. MacBook ProPro’s of this era will indeed run on magsafe power alongalone, but the problem is, that the CPU will then only run at 50%. I suppposesuppose it’s to prevent the magsafe from overheating, I’m not really sure.

Hopefully this info will help someone who needs it. I think my laptop has some weakness in the circuitrty that needs repairing, but it’s so awkward and expensive getting it done, so I just have to make do without. It could also be a problem with the Magsafe, or the battery itself, though it only has 16 recharges on it.
