Summary: I have owned this laptop for about 9 months. In that time, the hard drive has failed twice and the wifi has been throwing a "limited connectivity" message for some time now. The most recent issue is the battery is now giving an error, will not charge, and the laptop will shutdown if the plug is pulled (goodbye to all the uncommitted data in my database project, and two large stored procedures I wish I'd saved).
Summary: JUNK. We bought 8 at work. 4 needed new motherboards within the first month. 2 of those that had the motherboard replaced had to have a 2nd motherboard replacement within another month. These "computers" have the motherboard of a tablet. You're essentially buying a tablet with a laptop sized keyboard and screen.
Summary: There is a known defect. If you move or touch the laptop, it will die immediately. While typing, it has completely shut down without warning. Lenovo Community Forum has videos of it happening with the tilt of the screen. My experience has had it happen every time I try to use it. It has happened when typing and if I pick up the laptop to move it, it will die every time. There is an obvious defect. Lenovo support has been useless.
Summary: The x1 I received was used even though the review said new. It had fingerprints all over it, had a price missing and to top it off didn't even power up. What a disappointment. Not sure whose fault that was, but didn't order another.
Summary: It is a catastrophe for me to buy this laptop. You know, in China people say Lenovo is Americans' Lenovo coz two machine's price with the same configure vary a tremendous range from CN market to US', like this 2nd gen X1 carbon, about 2900 USD in China but only 1750 USD in the US, so I decided to but one from US amazon. About 25 days later I received it through forwarder company, so happy. But what I had not recognized is that it is just the beginning of a tragedy.
Summary: Stay away from this dealer. Out of the box Carbon X-1 from them was defective on delivery. Bad sound board/ speaker. No returns or exhanges if box open. On your own to deal with Lenovo. Hassle and time incredible. I would not purchase from them again.
