Lenovo is best brand I purchase in one year ago I have no problem faced in my laptop. It is good for the design and also good for the speakers. I have no problem about the battery or others.
It is better than other brand. Mostly I work in my laptop minimum 4 hours battery running to continuosly work. I like the battery back up. And lots of port in laptop. Only dislike of the laptop for Glossy plastic lid.
