Troubled from the start with chassis being warped lid not closing quickly replaced but another issue with cord slipping out then another fast replacement.. lve since learned these have an issue with ac cords not well designed so when the replacement came and was not too much better l opted for an invention sold here on amazon tethering it in place for 13usd. anyway l then had op system issues a blue screen an went through heck of a time resolving it by thumb drive install of new win 10. ..to this day it will shut on me and when l hit start but it returns to whatever screen l had up. research had me heat sink issue but it seems with a fan control app no real changes occurred. search stopped working and all the fix avaiolable online do not work..  l would not buy again due to apparent quality issues of batch buyer vendors of off lease machines like these guys  seems like too much slap shod repairs and lack of quality control
