In theory, you can, but pay attention to the line do not connect the wrong, otherwise the short circuit is over
1. Plug in the phone, and then use a multimeter to test the pass-through file. Four pins, code-named ABCD?
2. Test these four pins, which one is straight to the ground. When you find it, connect the black wire. That's the negative electrode.
3. General data line, both ends are positive and negative poles, find the negative pole,
4. The one furthest from the pin is usually positive. Which is to connect the red line.
5. Of course, this may be the positive terminal, the building owner can plug in the charger, connect the negative black wire,
6. Then touch the pin farthest from the negative pole with the red line, if it shows charging, it is the positive pole, connect it. If not, it's another pin.
7. Personally, it is possible that pin B is negative. But just guess, the most important thing is that the floor to measure the foot is with the machine motherboard ground line.
8. In this case, the white line D did not drop, the negative pole of the black line B, and the positive pole of the red line A are connected, and there is only one pin C left, which is directly connected to the green line.
9. After the connection is fixed, try to connect the computer. Generally, if the tail plug is normal, it can be used.
