Initially we suspected a bad monitor or cable. Used known good laptop and verified all components many times over.Eventually the video dropouts/image scrambling grew to such a point that the unit was unusable about 3 months after purchase. The unit also started shutting down and/or restarting randomly. That issue also grew worse over time.Tried the listed phone number for a warranty claim. Convoluted phone system. Can't even reach someone. Tried multiple times. Eventually left a VM in some random mailbox.Glad I purchased extra coverage through Asurion. I called them, filed a claim, easy enough, but I wish I just had a functioning computer in the first place.  :/
