Bought from Amazon, because it was advertised to function like new. To my disappointment, it would not even turn after being on the charger for two hours. I then purchased a new battery for it. Put it on the charger for an hour, and it turned on. I ran all the security updates, installed Google, watched a little you tube, and turned it off. 4 hours later, I tried to turn it on again, and it was like when I first got it. The seller then had me try starting it without the battery installed and on the charger. After holding the power button down for 10 seconds, it came on. Then putting the battery back on, it would not start. Put the new battery on, and the same result. I would not expect a computer that performs like new to be this way. Am returning. I would not buying refurbished.
