Chosen Solution
I got given this MacBook by a friend and he said that it was old so it took it as I need a new laptop. I came home to use it but when I plugged it in it stated to charge but nothing else would happen. I tried everything! SMC ResetPRAM ResetCleaning the logic board (there was no corrosion)Tring BOTH MagSafe 1 power adapters I have but none did anything useful.I checked if the SSD was working and t was I used another MacBook just to check. (It did work.)Nothing so far has gotten me further does anybody have any solutions?

Do the all of the LED’s light up and do they blink on and off? Update (11/19/2020) It does sound like the DC-In board has failed, here’s the guide to get to it MacBook Pro 17" Unibody MagSafe DC-In Board Replacement There is two versions which you’ll need to ID which yours is as you only told us you have the Core 2 Duo model which could be either as the last model uses newer part. A common cause of this failure is using a knockoff charger! Its very hard to tell the difference between a real unit and knock off. The only way I can tell for sure is the weight! The heaver unit is the real unit. Here’s one tell tale sign of a knockoff!

What color is the MagSafe LED when it’s connected to the system? Does it change when you perform an SMC reset? Sometimes a bad battery can prevent a machine from powering on. Try disconnecting the battery, holding the power button for 30 seconds, release, then reconnect the battery and connect a power adapter, then try to power on. If this doesn’t work you can try an SMC bypass. To do that, disconnect the battery and power adapter, then hold the power button for 10 seconds, reconnect the power adapter while still holding the power button, continue to hold for 10 seconds, then release. If successful the machine should bypass SMC sensors and force a powered on state.
