I've had my ASUS GL552VW for around 3 years now and it was working fine enough most of the time.

Today I turn it on (from sleep) and suddenly noticed a weird keyboard behavior. Once a pressed certain keys, the slash ("/") key started typing repeatedly.

From what I was able to tell the affected keys are: q x c v m , . ' right-shift right-ctrl, right-alt, numpad enter key

So what I press one of these keys the following happens, for instance when pressing Q: q////////////////
or when pressing X: x/////////////

The "/" key however is not working, nothing happens if I try to press it.... Also, the typing of the / from other keys stops if I press any key.


What I tried:
Removing the cap, cleaning the membrane around
Opening up the laptop to check the cable going to the motherboard, although there is no reason for it to be damaged since I haven't done anything to the laptop... no water spilled or pressed hard or smashed the keyboard, just regular day use.
Going into BIOS to check if it was OS related, it wasn't since it did the same on the BIOS password input as well



Any tips on this?


Thanks in advance


PS: in case anyone was wondering I typed this on the cheapest USB keyboard on the planet which I'm using as a replacement (which works fine)

Three things you can try...

1. Uninstall the keyboard driver, reboot without reinstalling it first allowing the computer to reinstall it on its own, and then see if this resolves it. NOTE: The external keyboard would have to be disconnected during this process (for the reboot).

2. Should the above not work, then try starting up the computer in "Safe Mode" and see if it works fine in there (not using external keyboard). If it does work fine, then you likely have a virus, malware, bad program, etc., on the computer that you need to remove to resolve the problem. Doing deep antivirus and malware scans should help. If it is a new program (or program update) then using "System Restore" to restore the computer to a date prior to the problem...

3. Should none of this work, then you are likely going to need to replace the keyboard.

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.
