unit came broken clearly no one spent any time making sure it all worked. touch pad mouse functions did not work, kind of obvious as soon as u turn it on and try to use mouse.  drivers missing in device manager, old version of windows installed 1803 (done 2 days before i got it), not patched either. Battery drained to empty. So if your offering certified you should build then test a few days before shipping. this thing went from used shelf to courier same day. Waste of my time.
