There are no instructions. It was not charged when I received it. I just plugged it in, 30 minutes after I received it and there is no battery indicator light that it is charging. I am so frustrated as this is the second preowned Apple Mac air pro computer that I bought. I don't need a lot of accessories, gaming etc. so I bought a cheaper model because all I wanna do is email and I need to do spreadsheet.Amazon is getting too involved with too many companies and are slacking up on the quality they used to provide! I am so disappointed and I am so frustrated!
