HP ProBook Ubuntu Bluetooth Not Working (FIX)

Symptoms

• Bluetooth toggle missing
• bluetooth.service inactive (dead)
• /sys/class/bluetooth does not exist
• bluetooth.service was skipped

---

Quick Fix

Reboot the laptop.

HP ProBooks sometimes cut power to the Bluetooth chip. A full reboot restores it.

---

Permanent Fix

1. Enable Bluetooth at boot

sudo systemctl enable bluetooth

---

2. Fix Bluetooth after suspend (HP bug)

Create a system sleep hook:

sudo nano /lib/systemd/system-sleep/bluetooth-fix

Paste:

#!/bin/sh
case "$1" in
  post)
    /sbin/modprobe btusb
    /bin/systemctl restart bluetooth
  ;;
esac

Save and exit:

• CTRL + O
• Enter
• CTRL + X

Make it executable:

sudo chmod +x /lib/systemd/system-sleep/bluetooth-fix

---

3. Auto-enable Bluetooth

sudo nano /etc/bluetooth/main.conf

Set:

AutoEnable=true

Restart Bluetooth:

sudo systemctl restart bluetooth

---

Emergency Command

If Bluetooth disappears again:

sudo modprobe -r btusb && sudo modprobe btusb && sudo systemctl restart bluetooth

---

Why this happens

HP ProBooks cut power to Bluetooth during suspend. Linux thinks the device no longer exists and skips the Bluetooth service.
