First of all, spend several months and the computer now requires RMA, Xotic was unable to help took me several times to request that RMA, then when I wanted to correct my review for them, they played dum-dum, all of them like they will put the request to correct it, that was my third time to request that correction as I am still waiting for my computer from RMA. If you know other suppliers use them Xotic will create nothing but stress and you will waste more money. Also heard sager is good, but $1400 machine with upgrades should not break down so quickly. The issue is screen not coming back from sleep, it wasn't software. User's recommendation: Avoid Xotic and Sager, plenty of choive.
