Hi, I initially had a problem when my battery was plugged in but it wasn't charging. Later on, after a few searches here and there, including on hp forums, I found a post that explained the problem. So, I followed the instructions in that post to the letter, and it worked. But not for long, I turned off the laptop at night and when I turned it on in the morning again, it displayed the same message, "Plugged in, not charging". I repeated the same steps and then it started to charge again, but then when I shut it down and turned it on again, it did the same thing. I can't keep doing this again and again, I need a permanent solution. I need to know if I need to replace the battery or something.
