Stopped working and won't power on.  Questionable just how much quality check and refurbishing actually takes place.  Save your money look elsewhere!Update: Had the computer checked by a reputable repair shop. Bad motherboard with voltage leak from CPU.  All this discovered approximately 10 days after warranty expired.  I believe this machine had little if any actual "refurbishing" completed by the seller. Additional tip off was the machine arrived with some sort of Chinese software on it.  Do not buy from this seller, rip off!!
