It should charge without any problem. If an old adapter worked properly, I recommend you to reset the SMC first before returning the adapter > http://support.apple.com/kb/HT3964
If it doesn't work, return the adapter and get a new one. The 85W adapter should work without any problem with the 17-inch MacBook Pro

First time I did the SMC reset, the charging light went off completely and the fans were blowing full speed.
I did it once more, and now everything's peachy again.
Thanks so much!
