Cordless mouse with mousepad included!! - Brand: Lenovo - Processor: AMD Ryzen 5 - OS: Windows 11 Purchase date is unknown. Usage frequency was quite low, only opened about twice a week for the first 2-3 months. Therefore, it is in good condition and has no operational problems. No instruction manual is included. I am not familiar with computers, so I may not be able to answer questions. I would appreciate it if you could look up information based on the serial number yourself. Serial number → PF3XG3KZ
