Hello everyone, this MacBook arrived at my workbench, but it wasn't turning on. I noticed that the G3H voltage was missing. I repaired the circuit, and the device started up again. However, the battery was too swollen, and I requested a replacement from the customer. Well, he bought a new battery, but the Mac won't charge at all. I've already checked the circuit and found the Q7065, which is failing to supply the 12V voltage to the battery. I replaced it with one (I had a similar scrap one), and even so, the voltage is still failing.

Can someone help me?
