Now I am going to shere my experience with Hp pavilion 15 Au144Tx. I am using it for about 13 months .I am very much satisfied with it . I brought it from a renowned online shopping site . They also gave me trusted product . Sound quality and picture quality is very good . Speed of laptop is also good . But only problem on my mouse pad .that is quite slow .But not very much . And they gave no laptop bag on that time . Charging capacity is also good . It can continue it’s battery about 3 to 3.5 hours . I am satisfied with it . I live Hp
