Rolling back to a previously used Display Adapter driver.Īt this point, I'm pretty lost as to what can be done, short of a factory reset, which I don't particularly want to do.

When I try to run the Toshiba Eco Utility update from Toshiba, selecting either the 'Repair' or 'Uninstall' options, the installer is unable to complete the operation as well. Even though other OSes might be compatible as well, we do not recommend applying this release on platforms other than the ones specified. If it has been installed, updating (overwrite-installing) may fix problems, add new functions, or expand existing ones.

When the computer tries to engage the Eco Utility, a pop up appears saying something about how the 'ordinal 8 cannot be located' in reference to 'teco.exe'. This package contains the files needed for installing the System driver. The Eco utility can't be opened, repaired, or uninstalled (at least not via the Toshiba update I downloaded above).

Note: I have a hunch the issue is linked to the Eco utility.

Attempted to install the latest Toshiba Eco Utility Driver.

Installed the latest Display driver that Toshiba offers for my model.

Changing the brightness using Power settings/other manual options does not work as well.

The slider that is supposed to pop up when the brightness controls are hit does not appear.

All the function keys work, except for those that control the brightness.

Display brightness is stuck at maximum.

For a long while now, I have been unable to adjust the brightness on the laptop, it's stuck at maximum.
