I own a Tuxedo (one of their previous models), they downplayed an official CVE in their firmware as "hyped", later promised patches but never delivered anything. A bigger problem though is the power-supply that is actually the same garbage as on my model. If you're moving the laptop around (or just tilting it with the cable in place) it will put pressure from the cable/connector directly onto the soldering on the motherboard - and break. I soldered it several times, and replaced the female part of the connector (on the motherboard) twice. The original problem with the power-supply is design: it can only be solved by replacing the connector with something more rugged. Thinkpads and Dell models have a comparatively large connection that goes in deep and stays in place no matter if you move it from your couch to a table. I literally can't carry this thing from A to B without first unplugging it and moving the cable/charger separately or it will be a matter of time until I gotta unpack the soldering iron again. The only option is to totally replace the power supply with a more rugged option, meaning I have to drill a bigger hole into the casing etc In my case there are also issues with the battery. It says 100% full but the battery capacity hints at an issue with one of the cells (notice the difference between capacity and percentage indicating a problem where GUI's tell you that you got 100% but you're out of juice in 30 mins): native-path: BAT0 vendor: Notebook model: BAT serial: 0001 power supply: yes updated: Thu 16 Dec 2021 12:44:05 AM (113 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 8.22528 Wh energy-empty: 0 Wh energy-full: 12.1414 Wh energy-full-design: 45.36 Wh energy-rate: 3.90096 W voltage: 17.399 V time to full: 1.0 hours percentage: 72% capacity: 24.7% technology: lithium-ion icon-name: 'battery-full-charging-symbolic' History (charge): 1639611845 72.000 charging History (rate): 1639611845 3.901 charging
