Email address: girija.t-s@hp.com and HP COMPUTERS product engineer Mr. Paul Amalraj are Forcing me believe to that I am wrong and HP COMPUTERS is not liable to what their dealer has told me to sell HP COMPUTER product i.e. SLATEBOOK X2 to me. They are calling me and repeatedly telling me the same thing over and over again that to get maximum battery life out of SLATEBOOK X2 I will have to use it in low power state which is totally opposite of what their dealer salesman told me. I specifically told the dealer that I would be using it for gaming and high multimedia use. This is very wrong on HP COMPUTERS dealer’s part to sell me this product by giving wrong information.
