SONY VAIO Z series, a notebook PC with all accessories included. It has a 256GB hard disk and 16GB of memory. It originally came with Windows 7, but it seems like Windows 11 can be installed and used. The battery is an L-type, but it only lasts for about 2 hours. I have used it since it was new. The CPU is a Core i7 from this era. - Brand: SONY - Model: VAIO Z series - Accessories: Instruction manual, AC adapter, battery, case - Keyboard layout: Japanese layout - Condition: Label on the back Thank you for viewing.
