Hi raffael,
If your
Toshiba R25-S3513 does not automatically change when you rotate the screen to tablet position, it is caused by a
missing or
corrupted driver. You need to keep checking the
Toshiba web site to see if they've released any drivers for your specific model. You can go
here. To refine the search, please select your
operating system and
Categories. If you can't find the accurate
driver, you need to wait until Toshiba releases new upgrades and updates for their drivers.
Hope it helps.
Thank you for using FixYa.
