Windows 11 turns off bluetooth
Hi, I have a problem that everytime I turn on my laptop, after some time, bluetooth functionality turns off (other wireless coms still work). Bluetooth basically dissapears from the device. There is no bluetooth "on" toggle swtich in settings, no bluetooth in device menager, none in services.msc.
I have menaged to turn it on by turning bluetooth off and on again in the BIOS, but after some time it again goes away.
I' ve tried to update the bluetooth drivers and disabled the ability for windows to turn off bluetooth for power menagment purpouses. Unfortunatelly with no success.
Big thanks in advance :)

Since toggling Bluetooth in BIOS brings it back, that suggests the issue could be at the firmware/BIOS level. Check if there’s a BIOS or chipset driver update from your laptop manufacturer — these often include fixes for disappearing devices.
Try disabling Fast Startup (Control Panel → Power Options → Choose what the power buttons do → Turn off fast startup). Some laptops lose devices after resuming. Also, make sure you’ve already unchecked “Allow the computer to turn off this device to save power” in Device Manager (once Bluetooth is visible).Your Bluetooth disappearing is likely due to a firmware or hardware issue. Try updating your BIOS, fully disabling power management for USB and Bluetooth devices, and check Event Viewer for related errors. If Bluetooth still vanishes, test with a Linux USB to rule out hardware failure. A USB Bluetooth dongle is a good fallback if nothing works.
In Device Manager > Bluetooth, disable the option “Allow the computer to turn off this device to save power” and update the Bluetooth driver to the latest version.
