Problem :
Going to the settings->Bluetooth page yields the ever
so nice “No Bluetooth Found” message despite my
laptop being equipped with Bluetooth.
Setup :
I’ve got an HP15-da1906nz Laptop running Fedora 36.
I’ve got the system root installed on an NVME SSD,
and my home folder is contained in a seperate 2.5"SSD which
is mounted into the system via an entry in fstab.
Context :
I’ve been running Fedora for a year now, Bluetooth has
never worked despite multiple attempts to remedy this.
I’ve tried multiple solutions described on this forum to no avail.
Did you try to update the BIOS? may need windows unfortunately (HP lazy doesn’t support lvfs).
I looked up your specs, almost exactly the same as mine, except mine shipped with freeDOS instead of windows.
A bit off topic, but how much battery runtime you get? On mine with the NVIDIA card disabled and light load, about 6-8h.
I’ve never been able to get my NVIDIA card to work either, nor have I tried.
Battery life is about 3-4 hours.
How does updating the BIOS work ? Do you install a windows utility onto
a usb drive, boot on it and do it there ? Is there a website where I can download
this and the potential BIOS update from HP.
You can get your NVIDIA card to work by installing nvidia drivers from RPMfusion.
If you don’t need the card like me, I disable the card using runtime PM since it draws about 2W on idle.
Copy paste this into a terminal:
echo '#!/bin/bash
# Disable Nvidia GPU while not used
echo 'auto' > '/sys/bus/pci/devices/0000:01:00.0/power/control'
# Fix Lid close acting like airplane mode key
setkeycodes e058 142
# Remove annoying dmesg log when pressing brightness up/down
setkeycodes e02b 240' | sudo tee /etc/rc.d/rc.local
chmod +x /etc/rc.d/rc.local
sudo /etc/rc.d/rc.local
If your device has the exact same motherboard, I expect you have the same issues as I have (no brightness up/down, close the lid=airplane mode), so I added my fixes to some issues to the answer.
