Managing External Displays

To connect external displays, use the HDMI 2.0 port or the Thunderbolt 4 ports. Windows 11 Pro allows you to configure multiple displays for extended desktop or mirrored modes. Access display settings by right-clicking on the desktop and selecting "Display settings". Ensure that the scaling and resolution settings for each monitor are correctly configured to avoid magnification issues when moving windows between screens. The recommended scaling is typically 100% for optimal clarity across different display sizes.

Wireless Connectivity

Your workstation is equipped with Intel WiFi 6 AX 201 and Bluetooth 5 for wireless connectivity. Connect to Wi-Fi networks and pair Bluetooth devices through the Windows settings menu.

Maintenance

Cleaning Your Workstation

Regularly clean the screen with a soft, lint-free cloth and a screen-safe cleaning solution. Use a soft brush or compressed air to remove dust from the keyboard and ventilation grilles. Avoid using harsh chemicals or abrasive materials.

Software Updates

Keep your Windows 11 Pro operating system and drivers updated to ensure optimal performance and security. You can check for updates through the Windows Update settings.

Battery Care

To prolong battery life, avoid extreme temperatures and fully discharging the battery frequently. The 4-Cell 64Whr battery is designed for mobile use.

Troubleshooting

Display Scaling Issues with External Monitors

If applications or text appear magnified or incorrectly sized when moved between your laptop screen and an external monitor, adjust the display scaling settings. Right-click on the desktop, select "Display settings", then choose the affected monitor. Under "Scale & layout", ensure the "Scale" percentage is set to the recommended value (often 100%) for that specific display. This helps maintain consistent sizing across different resolutions.

No Power

Ensure the power adapter is securely connected to both the workstation and a working power outlet. Check the power adapter for any damage. If the battery is completely drained, it may take a few minutes for the system to respond after connecting power.

Wireless Connectivity Problems

Verify that Wi-Fi and Bluetooth are enabled in Windows settings. Restart your router or modem if experiencing Wi-Fi issues. For Bluetooth, ensure devices are in pairing mode and within range.
