I have just bought a new (generic) laptop, sans OS, on which I have installed Linux Mint 14 Xfce (64-bit).
I am unable to activate the built-in 3G modem or the Bluetooth.
I know the Bluetooth was working when I originally booted from the Live CD. Wifi is turned on/off by Fn-F11 and Bluetooth by Fn-F12. I accidentally turned off the Bluetooth when trying to turn on the wifi. At the time I didn't worry as I assumed I could just turn Bluetooth on again later.
I did not have a SIM card available when I installed Mint, so I just ignored the 3G modem, again assuming I could set it up later.
Now I cannot get either device to turn on, and I am cannot find any evidence that Linux knows they exist (but I may not be looking in the right places).
Bluetooth is supposed to turn on/off with Fn-F12, and the single wifi/bluetooth LED should be orange if bluetooth is turned on. As far as I can tell, pressing Fn-F12 does nothing.
The 3G modem is supposed to turn on/off with Fn-[hyphen/underscore]. There is no hardware indicator of whether it is on, and I don't know where to look in Linux for a software indicator.
I suspect that these hotkeys are not actually doing anything, although Fn-F11 works perfectly for the wifi. If so, then can I turn the devices on some other way? and then how do I fix the hotkeys? Or if the problem is nothing to do with the keyboard, where do I start looking and what do I look for?
I can't see anything in lspci or lsusb that looks like either device. rfkill list shows the wifi device, but nothing else.
I found something relevant to Bluetooth at viewtopic.php?f=191&t=56621
although it is from 2011 so I don't know if it's still relevant. I will try it when I get home (don't have access to the laptop right now).
I don't know what the Bluetooth model is (it's not listed separately on the laptop order form, and as I said nothing in lspci or lsusb appears to be it).
The 3G modem is listed on the order form as EM770/Ericsson (although searching EM770 suggests it should be Huawei).
Any advice welcomed.
