I didn't have any issues for the past 2 years with my Alienware 14. But, today the battery started charging intermittently when plugged to the power. I unplugged the battery and turned on the laptop connected to the power. It worked well without power interruption at all. So, is the problem with the battery ? How do i fix this issue ?
It could be the battery, which would probably mean the battery needs replacing... or... which sounds more likely... it is the power cord that is the issue.
When a cord starts to go, it often will only run the device without charging the battery at the same time. Leading to what was happening for you. If you can borrow a cord from someone else and try it on your device, and try yours on theirs, that will give you a better ideas of if it is the issue.
