Troubleshooting

Laptop fails to detect external display via USB-C

Device is running hot during light tasks

Pros and Cons

Pros

  • Exceptionally powerful processor and GPU combination
  • Stunning 18-inch high-refresh-rate display
  • Comprehensive connectivity including Thunderbolt 5 and 2.5Gb Ethernet
  • Modern Wi-Fi 7 support for future-proof networking
  • High repairability index for long-term ownership

Cons

  • Heavier than standard ultrabooks at 3.2 kg

Setup, Compatibility & Care

When setting up your device, ensure you are connected to the included 280W power adapter during initial Windows updates to allow for maximum performance settings. The laptop supports USB Power Delivery up to 100W for travel convenience, though full gaming performance requires the dedicated AC adapter.

To care for your device:

  1. Maintain Airflow: Always operate on a hard, flat surface to ensure the intake fans on the bottom remain unobstructed.
  2. Clean Display: Use a microfiber cloth for the 18-inch screen to avoid scratches, as the anti-glare coating is sensitive to abrasive cleaners.
  3. Firmware Updates: Regularly check the Armoury Crate software for BIOS updates to ensure the best stability and NPU (Neural Processing Unit) compatibility.
  4. Battery Health: If keeping the laptop plugged in for long periods, consider setting a charge limit within the software to prolong battery lifespan.
