About two weeks ago I replaced my computer charger and battery because my computer wasn't charging. Now, it still isn't charging! It says 'plugged in, not charging' but luckily my battery was already at 80%. From the looks of it, the little pins inside the charger port keep bending. When they do, my computer doesn't detect the charger so I straighten them again with tweezers. My friend said there is supposed to be a little black thing over the pins and that's why they keep bending. So does that mean I need to replace the DC power jack? That's the only thing I can think of that might fix my problem so my computer will charge again. If that's not it, do you have any ideas of why it won't charge? BTW, I have a Dell Inspiron M5110. I bought it from a friend less than a year ago and I think she bought it in 2011 or so. PLEASE HELP!
