Hi. I was wondering I have the Asus X454LD-VX152H which is only a 5 days old laptop. It's actually a great laptop though the battery only lasts for about 2-3 hours now that is only web browsing and some youtube videos. Is the battery okay?The Power Plan is set to power saver. Also, the battery is a 2cell battery the sales person from the shop that I've bought told to me that the laptop will lasts for about 4-6 hours and 2-3 hours for gaming. The model of the battery is X550A26 btw.
