Thank you for viewing. This is a set of 3 NEC laptops. Please consider them as junk items. If you use the parts, please do so at your own risk. I am a novice, so I cannot answer specialized questions. All 3 machines power on, but they take an extremely long time to start up. I waited for several hours but gave up. One machine has been dropped, and the LCD screen is confirmed to be cracked. The other two were used for office work until a few years ago. There is no major damage. Everything in the first image is included. Feel free to comment. Thank you.
