It worked for a few months then it would not boot from nor charge the battery (would only work with external power).  Sent in to support who cleared all user info and reset to initial startup.  Repair report was blank and now system takes 15 to 30 minutes to load applications (some applications will not load). It will run from the battery but the best use now is for a doorstop or paper weight.  I would never buy another ASUS product.
