I briefly checked the main unit, and it worked without any particular problems. The absence of software stickers can be confirmed by the images to identify the software. Some software may require multiple insertions and removals. I haven't confirmed the startup of all the software. When the charger is moved, it sometimes doesn't charge, but it works fine if you don't move it while it's plugged in. Please refrain from purchasing if you are concerned about scratches or dirt. Thank you.
