Hello. I am bishal sah. I bought this laptop 6 months ago. It has a four cell bettery and a big LCD screen. Battery is enough to support LCD size and brightness. But when I see a whole movie of 3 Hrs. in my laptop it always turn off and shows battery low. The laptop is over all good but the battery is not so good and we can’t take long work from this laptop. My openion is I never buy laptop like thid again. Thank you.
