Fix 1 — Disable Filter Keys and Sticky Keys
Open Settings → Accessibility → Keyboard. Turn off Filter Keys and Sticky Keys. Both accessibility features can make a keyboard appear unresponsive. Filter Keys ignores brief keystrokes below a configured hold duration. Sticky Keys modifies key combinations. If either was accidentally activated, the external keyboard will appear to not register presses even though the hardware and driver are fully functional. This is the most common cause of sudden external keyboard input failure on the Dragonfly G4.
Fix 2 — Update Intel USB Controller Driver
Download the Intel USB driver for the HP Dragonfly G4 (Machine Type 8A3X4AV or similar) from HP Support. Install the Intel USB 3.2 eXtensible Host Controller driver. An outdated Intel USB controller driver on the Core i7-1365U (Raptor Lake-U) platform can fail to enumerate HID keyboard devices correctly after a USB suspend or system resume, causing the external keyboard to appear disconnected even while plugged in. The HP-certified Intel USB driver includes device enumeration stability improvements specific to the Dragonfly G4 USB controller configuration.
Per Norfaizah Ramli, executive using HP Dragonfly G4 for business travel with a USB keyboard: “External keyboard stopped working on the Dragonfly G4 when docked via a Thunderbolt hub. Filter Keys was accidentally on from pressing Shift too long. Turning it off in Accessibility Settings instantly restored all keyboard input.”
Fix 3 — Bluetooth Keyboard Pairing Reset
For a Bluetooth keyboard, open Settings → Bluetooth & devices. Remove the keyboard device and re-pair it. On the keyboard, hold the pairing button until the LED flashes. The Intel Wireless Bluetooth adapter on the Dragonfly G4 (Intel AX211) can lose the bonding key for a Bluetooth keyboard after a Windows update or Bluetooth driver update. Re-pairing from scratch creates a new bonding key that the AX211 Bluetooth adapter and the keyboard both accept for reliable input.
Fix 4 — Disable USB Port Power Management
Open Power Options → Change plan settings → Change advanced power settings → USB settings and set USB selective suspend to Disabled. On battery-optimized ultrabooks like the Dragonfly G4, USB selective suspend aggressively powers down USB-A ports when no data transfer is detected. A USB keyboard with short idle periods can have its port suspended and not wake up when the next key is pressed, producing an apparent keyboard disconnect that self-resolves only after physically reconnecting the keyboard.
Frequently Asked Questions
Why is an external keyboard not detected on HP Dragonfly G4?
Filter Keys or Sticky Keys is blocking input, USB Selective Suspend is powering off the USB port, the Intel USB controller driver needs updating, or a Bluetooth keyboard needs re-pairing. Check Accessibility Settings first for Filter Keys before investigating drivers.
How many USB ports does the HP Dragonfly G4 have?
Two Thunderbolt 4 USB-C ports and two USB 3.2 Gen 2 Type-A ports. All four ports support external keyboards. The Thunderbolt 4 ports also support USB-C to USB-A adapters for keyboards with standard USB-A cables. The Dragonfly G4 does not have a USB 2.0 port; all ports are USB 3.2 Gen 2 or higher.
Does HP Dragonfly G4 work with a wireless keyboard dongle?
Yes. A 2.4GHz USB dongle keyboard can be connected to any USB-A port on the Dragonfly G4. The dongle appears as a standard HID keyboard device. If the dongle keyboard stops working, replug the dongle into a different USB-A port and check that USB Selective Suspend is disabled for reliable 2.4GHz dongle keyboard operation.
Can I use an external keyboard with a Thunderbolt 4 dock on HP Dragonfly G4?
Yes. A keyboard connected to the USB-A ports on a Thunderbolt 4 dock should work when the dock is connected to the Dragonfly G4 Thunderbolt 4 port. Ensure the Intel Thunderbolt driver for the Dragonfly G4 is current from HP Support. If keyboard input through the dock is intermittent, connect the keyboard directly to the Dragonfly G4 USB-A port to confirm whether the issue is in the dock or the laptop USB controller.
Conclusion
External keyboard not detected on the HP Dragonfly G4 i7-1365U is most quickly fixed by checking Accessibility Settings for Filter Keys, disabling USB Selective Suspend in Power Options, and updating the Intel USB controller driver from HP Support. For Bluetooth keyboards, remove and re-pair in Windows Bluetooth settings. All four USB ports on the Dragonfly G4 support HID keyboard devices, so testing different ports helps isolate whether the issue is port-specific or affects all USB input.
