Supersede laptop's wireless adapter with usb wireless adapter

I am running Linux Mint 17.1 on a 32 bit laptop, Fujitsu S6240.

The built in wireless adapter, is, I believe a Broadcom BC5751M on the PCI buss. There is an external switch that allows one to turn it on or off.

I am attempting to use a ThinkPenguin N150USB USB wireless adapter. If I turn off the internal wireless with the switch, and insert the usb adapter it does not show up on the list of available connections. In fact, there is a red X for wired connections. If I then turn on the internal wireless adapter, I see two listings for most of the available networks, one associated with eth1 and one associated with wlan1.

I can connect to either one. If I remove the usb card, only the eth1 networks remain.

Again, with the internal wireless adapter's internal switch off, I cannot see any available networks. This is true if I boot with the usb adapter inserted or if I insert it after booting. If the internal wireless switch is set to off, the external wireless doesn't work.

If I am using the external adapter, I would like to turn off the internal wireless in order to minimize the battery drain. Any suggestions?

blacklist the broadcom driver aka kernel module.
a quick search will tell you how to do that for your distro.
after that reboot, what's the situation?
