I have a Dell Inspiron 1525 and it won't charge. When I plug it in the charger, all it says is "Plugged in, not charging." I have replaced the battery but it still won't work, what is going on? Also, there is not enough power in the computer to keep going, so the charger has to be plugged in 24/7 for the computer to run. The problem is the battery won't charge, it detects the charger and everything. I have taken it to computer shops and they say to change the hard drive which is useless because I don't have that much money. Is there any other way to fix the problem?
