How to Troubleshoot Keyboard Typing Lag

Techwalla may earn compensation through affiliate links in this story.

Typing lag most often occurs as the result of a lack of memory. Adding additional RAM to the memory slots can ameliorate this lag. However, even computers with sufficient memory can experience poor keyboard performance. "Filter Keys," a setting in the Windows "Accessibility Options," ignores short or repeated keystrokes, which a user may interpret as lag. Users can alter the keyboard's settings from the control panel to speed up the keyboard's response.


Step 1

Click "Start." Choose "Control Panel" from the right pane. Type "accessibility" into the search field. Press "Enter."

Step 2

Choose "Make the keyboard easier to use" from the options. Uncheck "Turn on Filter Keys."


Step 3

Click "Apply." Scroll to "See also." Choose "Keyboard Settings" from the links.

Step 4

Select the "Speed" tab. Drag the slider below "Repeat delay" to the right to decrease the amount of time it takes before the computer begins to repeat a specific key. Drag the slider below "Repeat rate" to the left to increase the rate at which Windows repeats a key.



Step 5

Click "OK" twice to save the changes.

Tips & Warnings

  • Close all open programs except "Notepad." Attempt to type into the application. If the keyboard no longer lags, a program is interfering with the performance of the device.
  • If you are using a USB keyboard, plug the keyboard directly into the PC. Don't plug the keyboard into a keyboard hub, which can interfere with the performance of high-performance keyboards.
