Chosen Solution

Hi crews, A friend of mine asked me to look into his dead MBP because the Apple care here in Germany refuses to repair this legacy device. It had the well-known “swollen battery issue” that destroyed the trackpad. I replaced the swollen battery and carefully cleaned up the computer (there was a lot of dust inside). I didn’t notice any trace of liquid damage. Everything looks okay. The problem is that the computer doesn’t turn on. I tried the following steps: SMC reset (disconnect the power supply, remove the battery, hold on the power button for 20 seconds). Then press the power button. No signs of life.disconnect the display, the keyboard and try to short the power pads. No signs of life either. The logic board seems to be dead. The battery charger does work as expected. Is there anything I could try out except the above mentioned steps before I throw the logic board into the trash?

Use a multimeter and test the mag-safe adapter, also examine the mag-safe board for output: Are you getting a green light on the adapter? If it has a battery test button, what is it showing. MacBook Pro 13" Unibody Mid 2010 DC-In Board Replacement
