Macbook pro a2141 16" 2019

Works, but is registered with an unknown account.

I bought it to repair only to find it's registered.  It had a problem with the lid angle sensor that stopped it turning on. The sensor been fixed and is fully working now.

It is the model with an i9 2.3ghz CPU, 5500m gpu, 16/512gb.

The top right corner of the lid is dented that affects the backlight slightly. See the photos.
