Since upgrading several Toshiba r500 laptops to Windows 7 (clean install), we can't get the backlight (transflective) button in the upper right to switch off backlighting so that the transflective feature (view the screen in full sun) works.
We've had several tickets open with Toshiba and are waiting on a response from a level 3 tech there. Lots of empty promises for a call back.
The Toshiba support forums are useless too, just a lot of unanswered questions.
What I'm wondering is if there's anyone out there with either XP or VIsta running on an R500 or R600. From what I gather, the Toshiba TVAP package installs the necessary software into c:\program files\toshiba\tbs This folder should have a backlight.exe executable in it, along with some supporting files. Anyone have these? I believe the xp/vista software will work fine on Windows 7.
