Hi Joshua, first of all, thanks a lot!

Hmm, good question. I will check. I actually hardly use Vista, but read that hot switching on Vista is possible. And I never suspended till now, or better, I did and the laptop froooozze. > I think I know what PCI config registers need to be poked, at least on my > SZ4, to change on the fly, but I haven't experimented to come up with a > reliable way of actually doing it (or changing over the all-important LED). Since I am not in need of it anyway, that is not important. >> after rebooting *from* Vista to Linux I see the following USB device: >> Bus 004 Device 002: ID 0af0:6911 Option >> which is an Option Globetrotter HSDPA Modem >> but cold-booting directly into linux this device does not appear >> functionality not tested since devices are strangly enough not created! >> Something similar has been reported in >> http://fedoraforum.org/forum/showthread.php?t=196654 > > I'm surprised that you get it when rebooting from Vista to Linux; usually > the BIOS shuts it off. I don't have my SZ with me, but there should be a If I shut down Vista and restart (cold boot) linux it is gone. If I tell Vista to restart and go directly from grub to linux it is there.

I never got it working, and I am always running in intel = stamina mode. Nothing whatever I do changes the brightness of the screen.

I have some application that allows me to switch on/off bluetooth, eth, modem, wwan, wlan. I will check the name.
