Why can't I change certain settings in Power Management or Windows Update on the PLC tablet?

Some settings in Power Management and Windows Update are intentionally locked to ensure optimal performance and stable tool connectivity.

Hilti has custom-optimized the tablet's power management configuration to provide the most stable and reliable wireless connection to Hilti devices — such as layout tools — over Wi-Fi and Bluetooth. These settings are carefully tuned to maintain communication stability even in challenging environments.

Allowing users to freely adjust these settings (e.g., to extend battery life) could unintentionally:

• Reduce radio performance or range

• Introduce instability in tool connectivity

• Lead to support cases that are difficult to trace back to power-related changes

To avoid this and ensure consistent performance, we restrict access to specific power-related options.

How do these settings affect driver updates?

Similarly, automatic driver updates are blocked, as well as some Windows Updates functionalities. This is because:

• New driver versions may introduce unexpected behavior or compatibility issues

• Every new driver release from hardware vendors cannot be tested immediately for stability

• Stability and communication quality could be negatively affected without warning

Restricting these updates helps maintain a validated and reliable system environment for layout tools.
