I have a Dell Inspiron 8200 and the cord is pulling out of the brick for the second time, so unless I can rip it open (it has no screws) and splice the cord back in I think I need another power adapter. I've been looking at APC's TravelPower (TPA90DC) and it seems good, but can't find their 'compatiblity guide' to determine if the Inspiron 8200 is supported. I've also checked out Targus' AC adapters, but haven't seen one that supports my notebook. Any recommendations? Thanks!
