charging port isn't charging, is it mean that the battery is dead?

I intend to repair it, to see if I am capable of doing so for my future career. I have some experience with repair, but not entirely 100% yet.

After I removed the screen, I noticed there was a black spot with a ring surrounding it. Does it seem like it's the spark from the battery? I assumed that the battery need to replace with a charging port. I just need someone to tell me if I'm correct or if I'm wrong.

If you've got it open for sure replace the battery. Go carefully, they are glued down and be cautious if you're using a heat gun to loosen up the sticky compound.

The charging port is likely filled with lint. Use a small pin/needle that can get down in there and just go gently scooping out all the debris. Get a light shining down in there too and make sure you don't have any fragments stuck or shorting out something.

FYI, you may have a more major issue at hand and if this basic troubleshooting doesn't resolve your issue you may need a new charging port or deeper investigation to see where the issue lies.

Hi Albert,

Yeah, that spot on the display does look as though it may have been from a spark from the battery. It's a little hard to tell from your picture, but if it is from a spark, there should be a corresponding mark on the battery itself in the same spot that would have been against the display; it appears there might have been one.

I agree 100% with Combat x Computers regarding replacing the battery and cleaning the port. Your strategy is sound; if the battery by itself doesn't fix the issue then the charging port should be next.
