Hello, i have this laptop for the last 3 years (1080p Version with GT 940M) and it does have a great battery live on the past two years. however, over the past few months i started to notice some issues with the battery, usually this laptop could last up to 5 to 6 hours of light task (browsing or doing my homework in WPS) and sometimes if i do gaming it last for 2 hours (i tested it with Wargame: Red Dragon). now, this laptop could only last 5 to 15 minutes on battery and sometimes if i charge it for several hours it still showing zero percent, i didn't see any battery damage indicator on the battery icon on task bar. is it the battery who faults or maybe there's something wrong in the software?
