I'm running TVSU on a Lenovo T500 type 2055-RL4 with Vista SP2. It indicates one of the updates available is a BIOS update, version 3.15-1.06. If I select this update to install, it appears to download (i.e. it shows the file download progress) but then I get the dialog saying "1 Package did not download". I've encountered this issue on multiple systems, and in each case other updates downloaded and installed just fine.
