Blah blah insert witty technical sounding things here... If this is one of the white plastic body MacBookss, please refer to a intro to DC 101... No seriously now, clean your connections.... 3 places in particular, 1.) The pins at the mag charge port outside and in (get the **** that has built up over the years out and also where the mag board connects to the logic board) DO NOT REATTACH YET!!! 2.) Now look straight down the side of the board, where the battery connector attaches to the logic board <--- REPEAT STEP 1 (Don't get excited yet, this is called preventative maintanence) STEP 3 AKA THE REPAIR) Now start unscrewing that pesky ALUMINUM frame or as I like to refer to it as "the thing that connects the battery to the ground plain". Make sure to disassemble in as many places as possible and clean both sides of the frame as possible. NOTE: As you do this please refer to the pile of white powder the will begin forming on your work area. Don't get excited this not an illegal substance and does not hold any kind of street value... It's ALUMINIUM OXIDE... The sad byproduct of a combination of time and aluminum. The nifty thing aluminum oxide is that it does NOT conduct electricity. It's a fantastically thin awesome insulator. Seriously clean this framework and your pin connectors... Don't negate the sockets or copper pads on the boards either. Now reassemble, and be amazed as to how well that old battery still dances around any windows machine... Battery life issues many times may also be resolved by this repair. But Always remember to check for a "BULGED" battery, if your battery is becoming lumpy do yourself a favor and shop amazon.

The System Management Controller is an integrated circuit (computer chip) that is on the logic board of the computer. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.
Over time, the settings in the System Management Controller may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not recognizing the AC Adapter, among others.
Resetting the SMC is not intended for resolution of a stall or situation in which the computer is unresponsive. An SMC reset should not be necessary except as a last resort in cases where a hardware issue with the power management system is suspected. Performing an SMC reset resets the hardware power management functions.
For most situations, a restart is sufficient. If the computer has stopped responding, try each one of these steps, one by one. Test between each step to see if it has worked. If one step works, don't worry about the next one. You should only reset the SMC if you've tried all of the steps listed here and the computer still isn't working.
