LENOVO ThinkCentre M75Q Gen2 Mini PC

Complete computer with all cables included.
The computer has been tested and powers on perfectly. It was turned on so the buyer could see that everything works as shown in the photos. It is in excellent condition and has been very well cared for.
This computer came from an abandoned warehouse and was won in an online auction.
The computer has a message that appears on the screen when it is turned on; the message displayed on the screen is as seen in the photos. I don't know if it belonged to a company or someone who used it for work or business.
I don't know if it belonged to a company; I'm not sure why, as I said, it came from an abandoned warehouse that was won online.
So I don't know the system it has, which is why it can't be accessed. Whoever buys it needs to know how to unlock or format it in order to use it
That's why I describe everything as thoroughly as possible in the description, so that the buyer knows exactly what they're getting and what will arrive at their address,
