ThinkPad X200 P8400 @ 2.26GHz, 4G RAM, 160 G HDD. Type Model: 7454-HT1. Bad Battery. Three USB, one VGA, one Ethernet, one audio output and one microphone input. Weight is about 3 lbs. In good condition. The battery is only good for about 10 mins, so you need to plug into power supply for normal usage. The screen, trackpoint and keyboard are all good, wifi works well. Light cosmetic wear won’t affect usage. With built in camera, microphone and keyboard light. X200 is the easiest to carry with model in the ThinkPad product line. I am not sure about the dimension and weight, but since it has no touchpad, it's the most compact one. I love the keyboard so much. I recommend using a Linux OS. It still well operates on Linux OS. It's very stable with Ubuntu, I used to keep it on for more than two months with no problems. It had the most fancy configuration at the time I bought it, now I think it’s still OK for daily work. I will format the whole HDD before giving it out. So you have to install the OS by yourself. No box, manual and other accessories, only with the power adapter. Pick up by yourself. No return and no guarantee.
