I think you should clarify over the phone 1st. I did my swap at c-zone today no hassle... Just bring along receipt and if possible your box too. I throw away my box but they still accept it but they will keep the new b3 box. Fine to me. Waited bout 30mins to 45mins and its done.

Do i need to reformat windows after the swap? The technician advised me to do so... Which is very troublesome for me.. Need to backup alot of stuff.
