Question Why does my Enter and Backspace act weirdly?

Feb 8, 2019
I have an Asus X540-YA laptop, and sometimes when I press the Backspace, instead of deleting the character, it writes down the combination of "74321", and sometimes some dots as well. Same thing with my Enter, sometimes it just types "nbz" instead of jumping a line when typing. I have tried to restore my Windows 10 the the original settings and re-install a driver ASUS sent me, but it did not help. Any suggestions what could cause it, or what could I do?
Try the following first. If that doesn't help, then I suggest you start up the laptop in "Safe Mode" and see if it happens in there. If it does, it is then likely hardware. If, however, it doesn't do this in "Safe Mode" then it could easily be something on the computer that is the cause. Bad program, virus, malware, etc., that you would have to remove to resolve the problem.

To try first...
  1. Uninstall the keyboard driver.
  2. Reboot the computer (without reinstalling the driver).
  3. When it restarts, it should reinstall the driver on its own.
If this doesn't work, you may wish to try connecting/reconnecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue.

Additionally, if your device uses one, you may want to try updating the Synaptics Driver if the above doesn't help.

You may also want to check the device for malware, viruses, etc., which can interfere with normal operation.

How to enter "Safe Mode" when booting the computer.

In Windows 8 and 10...

As your computer restarts, press F8 (possibly a few times) to enter "Safe Mode"

a. Press the "F4" key to Enable "Safe Mode".
(The computer will then start in "Safe Mode" with a minimal set of drivers and services.)

b. Press the "F5" key to Enable "Safe Mode" with Networking.
( Once "Safe Mode" with Networking starts, Windows is in Safe Mode, with additional network and services for accessing the Internet and other computers on your network.)

c. Press the "F6" key to Enable "Safe Mode" with Command Prompt.
(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. This option is mostly only used by IT professionals.)

Now sign in to the computer with your account name and password. (If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.

In Windows 7/Vista/XP...

1. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals.

2. The computer will then display hardware information and run a memory test.

3. Next the "Advanced Boot Options" menu will appear.

4. In the "Advanced Boot Options" menu use the arrow keys to select "Safe Mode" or "Safe Mode with Networking" and press ENTER.
