    Slim & light high-performance companion

    TUXEDO Stellaris Slim 15 - Gen6 - INTEL


    High performance in the smallest form factor: As most mobile addition to the series, the new TUXEDO Stellaris Slim 15 defines itself as a fashionable thin & light gaming ultrabook that focuses on high performance in a maximally slim and stylish appearance.

    The compact high-performance companion relies on an uncompromisingly thin and 2.1 kg lightweight, high-quality aluminum chassis in the brand new 15.3-inch format, in which it integrates an Intel Core i9-14900HX, an NVIDIA GeForce RTX 4060 or 4070, up to 64 GB DDR5-5600 RAM and a maximum capacity 99 Wh battery.

    Intel or AMD? Do you prefer the Stellaris Slim 15 with AMD Ryzen 7 8845HS? Please click here to get to the corresponding product page. If you value quieter and more pleasant fan acoustics over maximum portability, Stellaris 16 and Stellaris 17 run significantly quieter or cooler while delivering the same performance.

    Technical Details

    Display / Monitor

    Modern displays with IPS panels have bright areas along the frame as a normal characteristic. This has hardly any influence on everyday operation, not least because the displays are optimized for daylight operation. It can only be minimized, but not completely avoided, regardless of the manufacturer and for manufacturing reasons. Details on pixel error classes can be found here.

    Battery life:
    up to 15 hours at min. display-brightness, without Wifi & Bluetooth, without keyboard backlit, in idle mode
    up to 8 hours at medium brightness with Wifi, at office work


    We're testing battery time always in idle mode, at minimal display brightness, with keyboard backlight deactivated, Wi-Fi & Bluetooth disabled and without any further connected devices (USB, LAN, HDMI, VGA etc. unplugged!). We always test with integrated graphics when a dedicated and integrated graphics chip is installed.
    This way you get an information of maximal possible battery life. Starting from this, you can manage your individual battery life depending on your demands and to influence it, e.g. is keyboard backlight unnecessary during daylight. Bluetooth is also only needed to be turned on, if there's a Bluetooth device connected. Full display brightness as well is hardly always necessary.

    Cooling System & Fan

    Temperature controlled fan
    At low system workload, there is less heat emerging. The cooling system fans can spin accordingly slow or even turn themselves off completely. Depending on the chassis, cooling system and CPU and GPU, high to very high fan noise (air swooshing) is produced under full load. Thinner notebooks normally tend to get louder due to less cooling capacity.

    Custom performance and fan control with the TUXEDO Control Center
    With the TUXEDO Control Center you are able to control the performance and the behavior of the fans by yourself. This means that you get the ability to make your device as quiet as possible. By heavily reducing the performance you are able to set the device almost passive cooled, without any fan noise most of the time!

    System & Service

    Operating systems

    We install Ubuntu and TUXEDO OS (based on Ubuntu with KDE Plasma Desktop) in the latest 64-bit version with long term support.

    With our fully automatic installation WebFAI you can easily perform a Linux installation exactly as we at TUXEDO Computers do it in our production! You can choose from all distributions that we also offer in our configurator. Depending on the distribution, you have the choice between different desktop interfaces. More backgrounds and a video demo as well as detailed instructions can be found here.


    For "self-installers" and all who are interested, we have set up a database with downloads, instructions, tips & tricks and offer Tomte, a tool that automatically makes our adjustments under Ubuntu, elementary OS and Linux Mint:



    Encrypted Installation

    On request, we install your Linux system completely encrypted. The pre-installation as dual boot with Windows is technically not possible.
    Further details as well as a detailed introduction to encryption can be found here.


    Windows on request

    If you don't want or can't do without Windows, we install the desired Windows version next to Linux or alone. Please understand that a dual-boot installation can take 1-2 working days longer, even though the process is fully automatic. Please also note that we provide you with a correct Windows license incl. license sticker and installation DVD!


    Windows Drivers

    The corresponding Windows drivers are already included as standard with every device, regardless of whether it is with or without Windows or operating system installation. Alternatively, you are free to download all Windows-Drivers from here.


    UEFI firmware

    With all our notebooks, you have the possibility to protect your privacy already on firmware level using the UEFI (Unified Extensible Firmware Interface).


    For this purpose, the following functions can be completely deactivated:

    • On Intel CPUs: Intel Management Engine (IntelME)
    • Webcam
    • On Intel CPUs: Audio (Microphone & Sound)
    • WLAN & Bluetooth


    In addition, our Premium UEFI firmware allows chipset-specific settings and definitions for hardware components in order to run adjust the device optimally to your use case.


    Please note: All notebooks built in 2021 and later do not support switching the UEFI firmware to the outdated BIOS firmware standard.



    2 years pick up and return (12 months on wearing parts like battery & power supply)

    Optional: Up to 5 years pick up and return (12 months on wearing parts like battery & power supply)


    All devices have a maintenance-friendly design. Depending on the model, the essential hardware components such as processor, drive, hard disks, RAM, WIFI modules etc. can be accessed via maintenance flaps or removable floor trays. Furthermore the battery is replaceable if not stated differently. Of course, even after expiration of your warranty period, we're offering replacement parts and service for many years!


    For warranty cases, we'll provide you with a free return label after getting in touch with us. Warranty handling is done via our technical support. Please note our warranty conditions
