Quick answer

Why does your keyboard keep disconnecting? On a wireless keyboard it is usually a weak signal: the USB receiver sits behind a metal case or next to a USB 3.0 device, or the batteries are low. Put in fresh batteries, move the receiver near the keyboard on a short USB extension cable, and turn off the USB power-saving option. A wired keyboard that drops out needs a different port or cable.

Free fix vs. permanent fix

Free fix · 10 minutes

Fresh power, a better port, no power saving

  • Replace the batteries or fully charge the keyboard
  • Plug the receiver into a front or side port
  • Keep metal, external drives and Wi-Fi gear away from it
  • Switch off USB and Bluetooth power saving in Windows

How long it lasts: Fixes it for many people. If the receiver stays stuck behind the PC, the signal drops again.

A USB extension cable for the receiver

Most receivers are plugged into the back of a desktop, behind a metal case and next to noisy ports. An extension cable lets you put the receiver on the desk, in line of sight of the keyboard. That one move cures most dropouts and lag.

What to get: USB 2.0 extension cable, 3 to 6 feet

How long it lasts: Permanent. The receiver sits a foot or two from the keyboard in clear view, so the signal stays strong.

Why it happens

1

Low batteries

Weak batteries make a wireless keyboard lag and drop its connection well before it dies. Rechargeable keyboards behave the same way at a low charge.

2

A receiver hidden behind metal or too far away

A receiver in the back of a PC is shielded by the case and the desk. Metal desks, walls and distance weaken the signal.

3

Interference from USB 3.0 and Wi-Fi

USB 3.0 ports, external drives, routers and other 2.4 GHz gear can swamp the keyboard's radio. A hub or drive plugged in right next to the receiver is a common culprit.

4

Power-saving settings

Windows can switch off USB ports or Bluetooth radios to save power. The keyboard then lags awake or drops out.

5

A bad port or cable on a wired keyboard

A loose USB port or a frayed cable cuts the connection when you bump the desk. Try another port first.

Do these in order, starting with the simplest.

  1. Replace or recharge the power

    Tool used: Fresh batteries or a charged keyboard

    Put in fresh batteries, or charge the keyboard fully. Switch its power button off and on again.

  2. Move the receiver to a front or side port

    Tool used: Front or side USB port

    Unplug it and use a USB port on the front or side of the PC. If you can, keep it away from external drives and other USB 3.0 devices.

  3. Bring the receiver into view

    Tool used: USB extension cable

    Plug the extension cable into the PC and the receiver into its other end. Place the receiver on the desk, a foot or two from the keyboard, with nothing metal between them.

  4. Turn off power saving

    In Windows, open Device Manager, expand Universal Serial Bus controllers, open each USB Root Hub, and untick Allow the computer to turn off this device under Power Management. For Bluetooth, do the same on the Bluetooth radio's entry.

  5. Pair it again

    Remove the keyboard from the Bluetooth list, or re-run the receiver's pairing tool, then pair it again. Update the keyboard's software from the maker's site.

When free fixes aren't enough

If it still drops after fresh power and a clear line to the receiver, test the keyboard on another computer. If it drops there too, the keyboard is failing, so replace it. If a Bluetooth keyboard still lags near your PC, the PC's built-in Bluetooth may be weak, and a small USB Bluetooth adapter is an inexpensive fix. Stop using a rechargeable keyboard that swells, gets hot or smells, and unplug it.

Keyboard keeps disconnecting and reconnecting, or connecting and disconnecting? Read the pattern

  • Drops when you bump the desk: a loose port or cable, or a receiver at the edge of its range.
  • Drops after a few minutes idle: a power-saving or sleep setting.
  • Drops with lag first: low batteries or interference.
  • Drops near a router or phone charger: interference. Move the receiver away from it.

What to skip

Buying a new keyboard first

Fresh batteries and a closer receiver cost little, and a new wireless keyboard plugged into the same hidden rear port will often drop out too. Fix the signal path before you replace the keyboard.

Frequently asked questions

Why does my keyboard keep disconnecting and reconnecting?
A weak signal, low batteries or a power-saving setting makes the keyboard drop and then re-pair. Check the batteries and put the receiver in view first, then switch off USB power saving.
Why does my keyboard have a delay, and why is my keyboard lagging?
Lag is the early sign of low batteries, a weak signal or interference. Fresh batteries and a closer receiver fix most of it. A busy PC can also delay typing even when the keyboard is fine.
Why does my keyboard keep turning off?
Many wireless keyboards sleep after a few minutes of no use to save power, and a press of a key wakes them. If it turns off while you type, the battery is low or its power switch is loose.
How do I stop a wired keyboard from disconnecting?
Try another USB port on the PC itself rather than a hub. Check the cable for kinks near the plug. If it still drops, test it on another computer.
