Are you seeing an issue with discrete graphics after disabling Optimus?
If you are seeing the following problem on your laptop, follow the solution guide below.
If you have disabled the integrated or UMA graphic in Device Manager > Display Adapters, to get better video performance. A yellow bang appears against the discrete graphic card with an error message like Windows has stopped this device because it has reported problems (Code 43). The external displays, if you have one installed, stop working simultaneously. If you shut down or restart the laptop, the fault continues.
Note: This failure symptom can also be seen if the laptop has been re-imaged. However, the integrated or UMA graphic driver was not installed prior to installing the discrete graphics driver.
Note: Ensure that the integrated or UMA graphic driver is installed prior to the discrete graphics driver (both installed).
Follow these steps:
-
Enable the integrated or UMA graphic from Device Manager > Display Adapters and then reboot as it can bring the laptop back to the previous working state.
-
Ensure that performance and power-saving optimization is set correctly.
