Bose QC Ultra Keeps Disconnecting from My ThinkPad X1 Carbon

Hello!

I’ve been using my Bose QC Ultra headphones for a couple of months now. But in the last couple of weeks, I’ve been facing a weird disconnection issue with my laptop (Lenovo ThinkPad X1 Carbon running Windows 11 Pro).

Most of the time when I power on both my laptop and headphones, they fail to establish a stable connection. They just keep connecting and immediately disconnecting, until I manually click the Connect button.

Has anyone else faced this? Any idea how to fix it?

Things I’ve already tried:

• Hard reset the headphones
• Disabled multi-point connection
• Removed all paired devices (both laptop and headphones)
• Uninstalled the Bose app from my phone
• Uninstalled and reinstalled Bluetooth driver on my laptop
• Installed the latest drivers, BIOS update from Lenovo’s website, and all Windows updates

I’m out of ideas here. Any help would be appreciated!
