It's always a gamble when you purchase refurbished electronics. But for the price, I figured it was worth a shot.  I purchased this MacBook for my kid back in March and immediately noticed that the battery life was subpar. Under light use we would get 1-2 hours out of a full charge. But my kid needed it for school and I didn't want to deal with the downtime of having it replaced, so we just kept it plugged in.  Fast forward to November and the screen failed. Not from abuse, it's been treated very well. Best guess is that the wiring inside the hinge failed.  When opening the laptop, the screen turns on but as you continue to open it, it goes black.  Everything else about the computer seemed good. Visibly it was in very good condition, but it is now just an expensive paper weight.
