Nahashon ,first things first get hold of a simple multimeter n see if your adapter is outputing the rated Voltage ....19.5V ,20V as the case maybe .

if ts functional check if displaying ' plugged in Not charging ' thats probably your battery ,call me on 0722 335 273 i arrange for the replacement ASAP ,

if its the battery will get you one @ 4,500/= ,if its repair of your charging system will charge you 2,000/=

my regards
Branton.
