I am planning on replacing my inspiron 9300's DC power Jack myself (not for everyone). At current my laptop wont charge the battery(now dead)
so I have to use an alternate computer for now. Cant get much work done this way, but the part is on its way. I will tell you people how it went when I get back.
My previous post, is just one of the things I noticed about the plug. It may or may not be the true culperate as the small change shouldnt be enough to cause it to be disconnected. I say this because the same plug is currently powering a different laptop (same needs) just fine.
This is what tells me it's a problem within my laptop.
I did take it apart and took a look at the motherboard to see if I could determine if the jack was loose inside. I tested this by plugging the computer in while the motherboard was accessible to see if the jack moved around. It doesnt. I didn't look close enough to see if there were any burn marks/cold soder joints which could cause the power to be interupted, but since it is loose inside the jack, there must be a problem with the jack itself. I figure that the inside of the jack, it has a shaft that sticks out in the center that contains metal contacts on the outside, that are the culperate. More specifically I think they have weakened and dont stick out enough to hold onto the inside of the plug let alone keep electrical contact with the plug.
I will add more as I learn more.
