After 30 days amaZon isn’t very helpful. Purchased several computers and some have failed. Window fails to load making thr computers useless. They tell you that it comes with a 1 year warranty but that’s a lie. Amazon will tell you to call the manufacturer. The manufacturers will tell you the warranty expired a couple of years ago. When you contact the seller they simply respond it’s past the 90 days and they won’t replace it.
