Hello, I have a situation with my laptop. The deal is the power supply when I plug it into my laptop it is loose and does not charge my battery, what do you think?
Take a really closeup look at the charging port in the laptop.
Is there a centre post? Probably is one.
If so, then remove the laptop battery and proceed.
Look at the post. Does it have a split in it? Meaning that the post is not solid metal but 2 halves. If so then very gently slightly separate the two halves with a thin implement. Test connection. Repeat if necessary.
