Bluetooth not turning on

Hello once more,

I'm encountering issues with Bluetooth on my HP ProBook 4530s. It's quite perplexing; Bluetooth functions smoothly only about one out of every ten reboots. Most of the time, however, it fails to work. I've attempted to use Blueman, but it seems to only function when Bluetooth is already turned on.

Most of the time, the Bluetooth appears to be turned off, accompanied by the option to toggle it off again:

Also, here is the output of sudo /etc/init.d/bluetooth status when this happens:

Occasionally, however, it functions correctly as depicted in the following image:

However, in the current instance, although it shows as off, the option to turn it on is displayed, yet attempting to do so yields no result:

Here is the output of sudo lshw -C network:

I'm pretty noob at Linux but I don't think Firmware or Driver is the problem. But I see different and strange outputs from different commands.

here is the output of /etc/init.d/bluetooth status. (The Bluetooth is off):

here is the output of rfkill list:

	Hard blocked: no

Here, it is not showing any Bluetooth. But take a look at lsusb:

The outputs are very contradictory and I don't know really what to do. I've tried Drivers, Firmware, Blueman and Bluez and bunch of other methods.
And I know that the problem is not from the hardware itself, because it is working fine on my windows 10 and I've also tried it on Ubuntu 22.04

No solution?

I just found this from websearch "HP ProBook 4530s wifi switch" which may shed some light on bluetooth. Although this refers to wifi, isn't it the same card for both. I was thinking on the lines of physical switch being toggled or wireless status or Airplane mode being grabbed by Windows. When exiting Windows do a full shutdown.
Do you have Windows Fast Start disabled and BIOS Secure boot disabled?

Maybe a trip to your BIOS may reveal something.

I agree, it is contradictory. I would also lean toward Hardware issue.

I realize you say that the card works fine on Windows but-

  • how much testing has it had on Windows?
  • Hardware can show signs of failure sooner on GnuLinux than on Windows OS.

I agree that it is much better to examine the Software Side thoroughly before concluding it is hardware. Unless you have an easy access bluetooth card or USB dongle you can turn to without trouble, examining the software side allows the greatest chance to solve the issue without expense.

But, it is also more tedious.

As @zabadabadoo pointed out, the Bluetooth is radio and is therfor run by the Wifi card.
Have you checked your card and drivers?

sudo lshw -C network
