This system has NO battery,  After 8 days, aprox 19hrs of use by my wife doing some emails and web the screen started pixelating just by being turned on.  Seller is good, this unit is not.UPDATE: 02/23/2023, Sell has not replied on return, it has been well over 2 weeks. A seller that seemed to be good has become a non-dependable seller.  NEVER AGAIN
