More problematically, MSI employs mechanical switches only for the main typing area, with arrow keys and number pad using membrane switches despite the premium positioning .

The backlit haptic touchpad presents the most significant usability concern across multiple reviews. Tom's Hardware noted a "small delay between pressing and actuation that makes it seem sluggish" with click-and-drag operations proving particularly unreliable . Tom's Guide reported "gestures are hit and miss and click response is too slow". Windows settings adjustments failed to resolve these issues . Most users will likely rely on external mice, but the touchpad shortcomings represent an unacceptable compromise at this price point .^[4]

MSI Center serves as the primary control interface for power profiles, hardware monitoring, and keyboard configuration including Windows key disabling and Fn key remapping . Users can completely disable Nvidia Optimus to keep the RTX 5090 permanently active for maximum performance . However, customers noted frustration requiring multiple separate applications for system control rather than unified management. The Nahimic audio app provides equalizer adjustments that prove necessary given weak bass response from the speaker array .^[9]

Reliability and Thermal Management

The cooling system maintains component temperatures within acceptable ranges but generates substantial noise. Tom's Hardware measured keyboard surface temperature at 105°F between G and H keys, touchpad at 77°F, and maximum underside temperature of 109°F near exhaust fans during stress testing . While these temperatures permit comfortable operation, the fans create enough noise to be "audible across a living room" with an annoying high-pitch frequency . Fan behavior proves overreactive during light use, spinning up unexpectedly during web browsing and creating disruptive noise .

Pokde.net identified a critical reliability concern with Silent mode, describing it as "flat out unusable with how severely throttled the Core Ultra chip" becomes. This limitation effectively eliminates quiet operation as a realistic option for users requiring reasonable performance. The Balanced and Extreme Performance modes deliver expected capabilities but necessitate tolerance for aggressive fan noise.^[5]

The 1080p webcam provides adequate sharpness in well-lit conditions but deteriorates rapidly in low light . An infrared sensor enables Windows Hello facial recognition, and a sliding privacy shutter protects against unauthorized access .
