VPC Will Not Restart When ViewBoard Webcam Is Connected (BIOS Compatibility Issue)

Modified on Thu, 29 Jan at 4:08 PM

Overview / Purpose

When a ViewSonic VPC is used with a ViewBoard and the ViewSonic HD Webcam (VB‑CAM‑001) is connected, the VPC may fail to restart and remain stuck on the startup splash screen.

This article explains that the issue is caused by a BIOS compatibility limitation with ViewBoard accessories and provides the required BIOS update to restore proper restart behavior. After completing this article, customers will be able to successfully restart their VPC while connected to a ViewBoard and supported peripherals.

Affected Products

The following VPC models used with ViewBoard displays:

VPC15
VPC16
VPC17

Peripheral involved:

VB‑CAM‑001 (ViewSonic HD Webcam)

Issue Description

When Windows Restart is selected, the VPC may stop at the startup splash screen and fail to boot if the VB‑CAM‑001 webcam is connected to a ViewBoard.

If the VPC is powered off completely and then powered back on, the system boots normally.

Root Cause

The installed BIOS version is unable to properly re‑initialize certain ViewBoard‑connected peripherals during a Windows restart. This is a hardware compatibility issue, not a Windows or webcam failure.

Resolution: Update BIOS for ViewBoard Compatibility

Installing the updated BIOS improves peripheral re‑initialization and resolves the restart issue when using ViewBoard accessories.

Required BIOS Version

MT43V‑JHA 4‑V0.10‑A‑PD x64 or newer
