A:Answer It's possible the keyboard is faulty, but let's troubleshoot a few things first since the light turning on briefly is actually a good sign:
Try these steps:
Check/Replace Batteries
Weak batteries are the most common cause of this exact symptom
Replace with fresh batteries (even if you think they're new)
Make sure batteries are inserted correctly
Check for a USB Receiver
Some "wireless" keyboards use a small USB dongle/receiver, not Bluetooth
Look for a tiny USB receiver - it might be stored inside the keyboard's battery compartment
If found, plug it into a USB port on your HP computer
Try the Pairing Button
Look for a small "Connect" or pairing button on the keyboard (often on the bottom or back)
Press and hold it for 3-5 seconds to put it in pairing mode
Then try connecting via Bluetooth on your computer
Check Bluetooth on the Computer
Go to Settings > Bluetooth & devices
Make sure Bluetooth is turned ON
Click "Add device" and look for your keyboard
Power Cycle Everything
Turn off the keyboard
Restart your computer
Turn the keyboard back on and try pairing again
