What the test received

Press and release a key to begin.

Received taps

Event pulse stripPress any key · latest 0 events
A press draws the first pulse.

D = down · U = up · R = browser repeat. Gaps use received event times.

Tap any key to see its received press/release cycles.

One press seems to type twice

Completed cycles count received presses followed by releases. Held-key repeats are separate. Compare completed cycles with your deliberate tap count.

  1. Compare with a deliberate tap count

    Reset the board. Tap one key ten times, fully releasing between taps, and compare completed cycles with your own count. Avoid holding the key.

  2. Try a plain text editor

    Repeat those taps in another app. Review remaps, macros and text-expansion tools if the duplicate happens only in one app or profile.

  3. Check the connection

    Compare a direct USB port or a supported wired mode; check wireless charge. Change one condition at a time.

  4. Use the exact model’s repair path

    Follow its official cleaning and firmware advice. Corsair provides a specific double-typing support path for the K70 Core; its remedy is not a universal fix for other keyboards.

Retest

After each change, reset and repeat the same ten fully released taps. Auto-repeat during a hold should not increase the completed-cycle count.

If it persists

If duplicate taps persist across apps and connections, ask the manufacturer for service. Do not remove switches unless your model’s instructions explicitly permit it.
