I also want to point out that I am not a professional computer refurbish guy. All I did was to upgrade the RAM, hard drive, and then to install the Windows 7 Professional using Lenovo's system restore disks. I have also updated the Windows to its latest version including the drivers and other files provided by Lenovo's system update.

Thinkpad x230 tablet PC: Serial number: PK-19WN3, Model: 3435-22U. Please search Lenovo's website to make sure it has all the specifications that you need.
It comes with a backlit keyboard.
I have upgraded the RAM to 16 GB.
Hard drive is Samsung SSD 500 GB.
It comes with Thinkpad UltraBase Series 3 docking station.
Includes Lenovo Slice battery FRU P/N 42T4967. The slide lock mechanism is broken, but the tablet PC will stay in place when latched on to the slice battery.
Adapter that converts the yellow round tip to USB-C pin. I use this to charge the laptop with a high wattage power bank.
Lenovo 65 watt power adapter.
Original Lenovo stylus with tool to replace the stylus tips. It comes with 5 additional tips.
DVD-RW drive for the docking station. FRU P/N: 45N7451
Thinkpad Serial ATA Hard Drive Bay Adapter III: FRU P/N: 43N3429. I am also including a 240 Gb Crucial SSD. I used this to back up my data. The back up is much faster because of the SAT connection in the dock via the adapter.
Thinkvision LT1423p external monitor that powers via the x230 tablet. The monitor is missing the stylus.
I have included a picture of the battery condition and count. The time that Lenovo gives is all over the place and honestly I don't put much weight on those numbers.
