Lenevo Ideapad Z510 is very worst laptop/notebook because of it have bluish screen and having low contrast we don’t see its display comfortable in huge amount of sunshine. its low contrast make its worst laptop.
The other big problem is it make noise while burning a CD/DVD. if we burning a CD/DVD with using some burning tools. This make Very noise like suuuuuuu. and make until the DVD/CD completes its action.It contains hd display but due to low contrast and bluish it can be worst always.
