Plugged it in as soon as I received it. Waited 10-20 minutes and when I went to unplug the flat faced charger, the thing was so hot, I burned my thumb. After that, I would only allow the charger to stay pluged in for 10 minutes. Never had long use time with this computer. Seller said he would send new charger but, never did. One month later it started to freeze up after using for only 10 minutes. Between the charger and the screen I've decided to send this piece of junk back. Way to frustrating in dealing with amazon and this seller.“Best computer I’ve ever owned” per my son. Super fast and perfect for college.
