Bought this for my son in late May, for his use in school. His new school didn't start until beginning of September and he's used it for a month now. It constantly turns off on it own, and it doesn't matter if the battery is at 90%, 65%, or 25%. Contacted company and their response was that it is not covered by 90 day warranty. Lesson learned, never again.Update... took laptop to be diagnosed and repaired, and was told the motherboard was bad, probably bc it was old. Not a very good refurbishment..smh
