I've only had the computer for 3 days so this is about setting it up, not how it works.It arrived in a factory-sealed box so it obviously hadn't been opened. Its contents included the TC-895, keyboard, and mouse, as advertised. There was also a 6-inch cable labeled Serial ATA, the usual very-small-print warranty, FCC and EU Declaration of Conformity that included info on power management and a page with what appears to be drawings of what needs to be plugged in, and flyer titled, "Got a Question About Your New Acer Device? Ask Us!"Usually these days a new electronic device of any complexity has a poster-size or foldout series of illustrations and instructions on initial setup, and in the case of a PC a well as a photo or drawing showing labeling the types of ports or plugins on the front and back. If you want anything more you go to the website and download a PDF users manual. So I thought I'd see if maybe it was missing and there was one online.I was easily able to find the proper Acer support page. There I found the Users Manual but no Setup Guide. The users manual said nothing about initial setup. BUT, it referenced the Startup Guide/Poster that doesn't exist either in the box or under my computer model's online documentation list. The hour was late but I decided to chat with Amazon tech support. Abdul was helpful in that he told be what the ATA cable was for (in case I wanted to add a component) but could find nothing about set up. He did offer to set up a return, however, if I wanted to send it back. I declined.Next I called Acer support. I was quickly connected with a representative who had no more luck than Abdul at Amazon. Trying to be ever so helpful he offered to walk me through the setup process. By then it was almost 10 pm and I'm not a night owl so thanked him and said I'd call back.The next day I decided to just plug it all in and see how I did. It went well. By Day 2 I was able to identify the front and back ports (some of which had microscopically small symbols beside them). I was unaware until now that there are 3 types of USB connections.The bottom line is that Acer should have some simple documentation packed with its computers. It would save a lot of time and frustration for those of us who aren't tech wizards.Now I just hope the thing continues to work.
