Dies while plugged in. Apple said that generic charging block is not sufficient for device. Got an Apple 140w block and cable to replace what I received. Laptop will only charge correctly if lid is open, just makes beeping sounds when the lid is closed. Apple stated that because it is a renewed device that the seller probably replaced the original battery with an aftermarket lower quality battery. Couldn't find a way to message the seller about concern so 1.5 months later, not very happy with purchase. Will not purchase again, advise others to check your device thoroughly if you choose to purchase.
