BUYER BEWARE!!!… this “EXCELLENT” condition MacBoom Air (I purchased for my daughter who graduated) ONLY STAYS ON WHEN CONNECTED TO CHARGER)!!!The battery icon went from 44% charged, then 39%, then 1% all within 2 minutes of using after charging for 4 hours! The battery icon shows 1% now even when connected to the charger….So Disappointing!I did the troubleshooting steps. I called tech. They told me I have to return for a refund.I am Definitely Returning this!!! I was told by the tech someone would be picking this up for the return by Telecom (never heard of Telecom) or UPS and I had to wait until Monday (2 days from now)…My money was taken right away. Let’s see how long it is before my money is returned to my card…I won’t be using Amazon Renew Store to purchase items again!
