Complain: I having to restart after each boot up as on first (cold) start since this update the keyboard on Lenovo laptop does not work. But when I reboot , the keyboard is back to normal.

Solution: This is a common driver compatibility issue. Please try disabling Fast Startup.

1. Open the Control Panel by typing “Control Panel” into the Windows search bar and hitting Enter.
2. Navigate to “Hardware and Sound,” then select “Power Options.”
3. On the left-hand side, click on “Choose what the power buttons do.”
4. Click on the link that says “Change settings that are currently unavailable” to unlock the settings.
5. Uncheck the box that says “Turn on Fast Startup (recommended).”
6. Click “Save changes” to apply the new settings.

Disabling Fast Startup means your computer will take a little longer to boot up, but it can help solve various issues related to updates and hardware compatibility. To completely fix this issue, you may need to wait for system and driver updates.

Run “Windows Powershell ” as Admin;

The below DC voltage drop cable distance chart works as follows. The left column notes the amount of power that the device you are powering requires (red text). The “mA” after the number stands for milli-amps. For example, say you are using a CCTV camera that requires max 300mA. Using 18 gauge power cable, you can run your cable up to 289 feet.

This is an intentional limitation to reduce cellular broadband bandwidth usage. If you require more than 5 minutes of Live View, we recommend adding your device via IP Domain on the Hik-Connect app with port forwarding.
