    When the laptop is not connected to AC adapter, Gpu & fans and keyboard light stops working


    I have been using an ASUS TUF Gaming F15 FX506HE, which has integrated GPUs: Intel UHD Graphics and NVIDIA GeForce RTX 3050 Ti.Everything was functioning normally until I opened my laptop to apply thermal paste. After that, whenever my laptop is not connected to the AC adapter, the NVIDIA GPU is missing, and the laptop fans and keyboard lights stop working. When I connect it to the adapter, the GPU starts working, as do the fans although sometimes the fans don't work, and I need to restart the computer. However, the keyboard lights seem to be stuck in "breathing" mode.How can I solve these i

    :)

  3. Discrete GPU not being used when laptop is connected to AC adapter

    Hi Rhianna,

    Welcome to Microsoft Community.

    I'm Hahn and I'm here to help you with your concern.

    I'm sorry to hear about the issues you're experiencing with your laptop. It can indeed be frustrating when a previously functioning system starts acting up. Based on the information you've provided, it seems like the laptop is not switching to the discrete GPU (GTX 3070Ti) when it's connected to the AC adapter, causing crashes in games.

    - Some laptops come with their own software for power management and GPU switching. Check if there's any Alienware-specific software that might be affecting GPU behavior.

    - Run diagnostics on your laptop to rule out any hardware issues. Dell laptops typically have built-in diagnostics tools that you can access during startup by pressing a specific key and selecting the diagnostics option.

    - If all else fails, you might consider performing a factory reset to bring your laptop back to its original state. Ensure you back up your important data before doing this.

    Since you've already contacted Dell support and even hired an IT specialist with no success, it might be a good idea to follow up with Dell and provide them with all the details and steps you've taken. They should have the most accurate knowledge of how their hardware and software work together and may be able to provide a solution or suggest further action.

    I hope this helps. If there is anything not clear, please do not hesitate to let me know.



    Your Sincerely

    When the laptop is not connected to AC adapter, Gpu & fans and keyboard light stops working

    Windows 10 fan running loud and non-stop

    Hi JKaris,

    Let’s remove the battery from the computer and run the laptop on AC power supply and check if the
    fan makes noise.

    Also perform a hard reset and check if it helps.

    • Turn off the Laptop.
    • Disconnect all peripheral devices and remove all USB devices and media cards.
    • Disconnect the AC power adapter and remove the battery.
    • Press and hold the power button for at least 15 seconds.
    • Connect the battery, reconnect the AC power adapter.
    • Turn on the Laptop.
    Try this and update us the results.
