Microsoft Surface Bluetooth Connection Issues

Question

I currently use a Microsoft Surface Pro for Business 11th Edition with Intel for work and have a Bluetooth keyboard and mouse connected to it. Over the past few weeks, I’ve noticed that both devices randomly disconnect at least twice a day.

I’m not sure if this started after a recent update or if there’s another issue causing it, but it’s becoming really frustrating.

Yesterday, while I was typing, the Bluetooth connection suddenly dropped, and my keyboard started typing “cccccccccccccccccccc” across the screen. I couldn’t get it to stop until I was able to reconnect everything.

Has anyone else experienced this issue with a Surface and Bluetooth keyboard/mouse? Any suggestions for troubleshooting would be greatly appreciated!

Answer 1

The stuck "cccccccccc" repeat when the connection drops is a classic symptom: Bluetooth HID drops the "key up" signal mid-keystroke, so Windows thinks that key is still held down until you force a reconnect. That's a driver/firmware-level Bluetooth stack issue, not a hardware fault in your keyboard.

Device Manager → Bluetooth → Intel Wireless Bluetooth → Power Management tab → uncheck "Allow the computer to turn off this device to save power." This is the fix most people report actually working.

If that doesn't hold: remove and re-pair both devices fresh, and check Windows Update → Advanced options → Optional updates for a newer Surface firmware/Bluetooth driver.

If it's still unreliable: switch to a USB dongle-based keyboard/mouse instead of Bluetooth — this is a hardware-level Bluetooth stack issue, not your peripherals, so a dongle sidesteps it entirely.
