Hi
I am pretty sure this is a real Toshiba!
The model seems not to be an EMEA model though so it could be that it originates from another region of Toshiba - like Toshiba Asia.
Use your model number, the coplete PSK2YE-number you mentioned below along with the real serial which always is 9 charachters long ending with a letter (syntax 12345678A, X1234567A, 1X234567A or XY123456A - please understand that those are examples showing the syntax only - your letters and digits will be different!) and look them up here:

If you enter the proper information there you should be able to look up your PC.
Good luck
