Dell laptop n5010 has a biggest problem, that is, it gets hot within few minutes . and this will shuts down automatically whenever it gets too much hot, that is like about after an hour.
N5010 has no graphic card, so no chance of playing high resolution games.
Many people have written that it gives just 4 hour backup. While writing this review, my battery with 60% charge shows hours 1 hour 10 minutes remaining.
