I install ubuntu 22.04 on my laptop (Vivobook-ASUSLaptop-X1502ZA-R1502ZA). When I want to turn on the Bluetooth from settings, I got the "No Bluetooth Found" message. I tried different solutions but got nothing. I ran sudo service bluetooth status and got:

○ bluetooth.service - Bluetooth service
    Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor pre>
    Active: inactive (dead)
      Docs: man:bluetoothd(8)

Also, this is the output of lspci -knn | grep Net -A3; lsusb; sudo dmesg | grep -i blue:

Update

When I ran the following command:

sudo modprobe btusb
sudo rmmod btusb
sudo systemctl start Bluetooth

Get these outputs for the sudo dmesg | grep -i blue

`lsusb` doesn't show a USB BT device, so trying to start `btusb` is useless. The debvice is either disabled in BIOS, or is using some other interface. Most likely it is not supported by Ubuntu kernels. You can report a bug by `ubuntu-bug linux`. Try to install the latest mainline kernel and check if it is supported there.

I had the same issue for a couple of weeks now. what worked for me is to power-off the computer entirely, even removing the power cable for a while and then turning it back on. Based on this thread:

In your case since it's a laptop you might need to remove the battery.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
