A user reports that the C key sometimes will not register or registers multiple times. The problem only affects the C key.
What should you do?
1. Use Accessibility Options to disable StickyKeys.
2. >>Use tweezers to remove the debris from around the key.
3. Dust the keyboard using a soft cloth and window cleaner.
4. Install a new keyboard driver.
Explanation : The problem is most likely caused by debris under or around the C key. You can remove the debris with tweezers. Or if the entire keyboard seems dirty, you can use compressed air to blow out the debris or shake the debris to one end and pick it out with tweezers.
You should not spray window cleaner on a keyboard. You should avoid getting liquid under the keycaps. If you need to clean a keyboard's keys, avoid getting liquid under the keys.
Disabling StickyKeys will not solve the problem. StickyKeys is an accessibility feature that helps users who cannot press multiple keys at once activate key sequences.
The problem is not likely caused by a keyboard driver. The most likely cause of the problem is debris under the key.
