I had to replace my battery after owning it less than 3 months because it wouldn't turn on at all. replaced it under warranty, worked fine for a bit, then the same issue again. After 3 years of pretending I didn't waste me money on a dell product I've decided to revisit the laptop. Does anyone know what the issue might be? Should I replace the battery and hope for the best? Or replace it and sell it to someone who is none the wiser?
