Issue: When VPC restarts, it will stop and remain on the startup splash screen. If the VPC is powered off and then powered on, unit will boot as expected.
Cause: VPC BIOS is unable to reload the ViewSonic webcam (VB-CAM-001) driver when a RESTART of Windows is selected.
Solution:
Bios update: Download an updated Bios file for the model below and follow installation instructions. Instructions are located in the zipped file.
Project Version of BIOS should be MT43V-JHA 4-V0.10-A-PD x64 or newer
