This Lenovo ThinkPad my wife gave me for my birthday. I opened it and didn't see the CD/DVD Drive (on my old Lenovo desktop Tower PC - it is and sometimes I use it), therefore I closed and didn't open this again. This is Brand New, never used and plugged in power. As I know, Memory: 16 GB and Hard Drive: 512 GB. For more accurate and additional information, you can go to the Lenovo website using Part Number: 20SQS01P00 and S/N: PF206DPT. A total of $1,806.24 was paid for it.
