I have a question can someone help me further My laptop charging socket & battery are defective I have considered my laptop mainboard has 7 pins & I just want to know where the plus and minus lies I want to connect my old power supply directly to the mainboard to operate Thank you in advance
Why don't you solder the strip exactly where the charging socket is now?
this would also clarify the polarity
The maindboard charging socket is burned
Well… Unsolder and use the soldering points… Is that not possible?
The solder points are burned out & i don't know where plus & minus is
