Once you start moving the laptop it starts giving the issue.8 time out of 10 time if I pick up the laptop to move to other place then it crashes and it gives zombi sound. also, it's Touchpad/Mousepad location is also not correct it takes time to adjust.Other then this this laptop is ok no issue.Sep Update: One of worst laptop I have ever used. It crashes 15-20 times a day. you never know when it will crash. sometimes  just by going to amazon.com it crashes. I think 1 star rating is proper. I would suggest ignore buying this laptop.
