how to modify laptop power jack? Answered
So hey there instructablers! I had a laptop with a loose power jack and a bad battery that was working perfect but when i moved the charger a little bit it was losing contact so it was turning off. One day i decided to rip apart the laptop and see if i could fix it. I opened it only to find that the jack had completely come out of the board! So i came up with the idea to solder the charger wires directly to the board without a jack. It seems possible, right? But i got into a problem! I couldn't find which of the remain lead was the positive and negative. I have attached a photo and i have circled the jack lead and number them. If anybody could help me buy explaining me which lead does what i would appreciate it! Thanks in advance!
