Thank you for viewing. Model Name...Panasonic Let's Note CF-RZ4 Silver Memory...4GB Graphics Board Type...Not installed Storage Type...SSD Storage Capacity...128GB Wifi, keyboard, and touch panel are working properly. OS...None (It was working with Windows 10) The screen is generally yellowed. There are mottled patterns and white patterns in the center of the screen. Power is difficult to turn on (a symptom unique to Panasonic notebooks). Power adapter included. (Made by Panasonic, but it is unknown if it is the genuine product for this model.)
