Problem

When the user powers on their HUAWEI MateView monitor and touches the Smart Bar, it does not respond.

Cause

When the monitor is connected to a power supply, the Smart Bar will perform automatic detection and calibration to determine the benchmark capacitor. If external interference occurs, there is a low probability of detection and calibration failure, which will cause the Smart Bar to fail to respond to touches.

Solution

1. Ensure that the triangle socket or plug for the monitor's power adapter is grounded. It is recommended that you use a triangle socket on the wall.
2. Disconnect the HUAWEI MateView monitor's power adapter from the power supply and connect them again.
3. If you are using the Smart Bar for the first time, it is recommended that you connect a USB mouse to the USB-A port on the side of the monitor, click OK on the navigation pane, enter the desktop, and check whether the Smart Bar can be used normally.
4. If you are using the HUAWEI MateView wireless edition, update the monitor system version to 249 or later. For details, see Updating the monitor's system and driver (only on HSN-CBA monitors).
