Looking for replacement notebook power supply

I'm trying to find a replacement notebook power supply for a Clevo M67SU / M67SRU Notebook power details:

19V 4.7A 90W Max

Current unit given to me by the teacher is a Li Shin Int Ent Corp Model 0335C2065 Input 100-240V 50-60Hz 1.7A Output 20V 3.25A Bears a Green and Black coloured stick on label 20Y17LF-B301

Any recommendations please?

You just need any 19V, min 4.7A supply. Clevo D400 AC Adapter would do the job.
