Hi All,

I have found that a BIOS update has solved these problems. If you go to the official Toshiba website you can download a BIOS update utility (under the Windows Vista software updates).

When I first tried to run the "Vista" utility it failed. But Windows automatically applied a "compatibility" fix and asked me to run it again (I think it was just running the tool as Administrator). When I ran the tool again the BIOS was updated and the machine was restarted. Since then, all of the issues I was having have been resolved.

Hope this helps.
