I have a HP Compaq Presario C700 laptop with Windows 7 installed on it.

My laptop's keyboard is not working properly; some keys never work and some keys will keep on pressing. I've formatted the OS but it didn't solve my problem.

I bought an external USB keyboard and it works well. As some keys in the built-in keyboard activate themselves, I still couldn't work effectively.

After searching Google I tried the following steps to disable the built-in keyboard:

  1. Disabled keyboard drivers:
    This didn't work because when the system reboots, the driver gets installed again automatically.

  2. Installed irrelevant driver for keyboard:
    This failed - I couldn't install the driver. After rebooting it installed the correct driver automatically.

Can anyone help explain how I can temporarily uninstall my built-in keyboard? I don't want to remove it manually (removing the hardware cable).

twitch Windows Vista? Windows 7? There's no Windows 2007, it's Office 2003, 2007, or 2010. –  tombull89 Oct 14 '11 at 14:12

I'm not familiar enough with this machine to tell you how easy it is, but generally the keyboard on a machine like this is end-user replaceable, so you could simply replace it. Alternatively, you could just open the machine and unplug the data cable connecting it to the motherboard. (I suggest this way specifically so that it doesn't cause you grief in the BIOS or something like that, if the occasion arises.)

@sam - I have no idea what you're trying to ask. "Remove my machine"? –  Shinrai Oct 16 '11 at 5:17
    
i don't need to remove my laptop manually and remove the keyboard's harware cable. Another another way other than this? –  sam Oct 19 '11 at 15:50
    
It's the best way to do it - if you're afraid to open it, I don't know what to tell you. –  Shinrai Oct 19 '11 at 16:17
    
Also, it sounds like you don't speak English natively, so I'm not sure I understand you correctly, but it sounds like you're trying to say that you would prefer not to do this. If I read you word for word it sounds like you mean you're physically incapable of it for some reason - if that's the case please say so. –  Shinrai Oct 19 '11 at 16:31

Look at this article, it will help you to disable your laptop keyboard by uninstalling your keyboard driver.

  • Go to Start–>Search type in gpedit.msc
  • Click the file to open the Local Group Policy Editor and show Windows who is in control!! You want to go here: Computer Configuration->Administrative Templates->System->Device Installation. Click on the subfolder Device Installation on the left and on the right side you will see the possible restrictions.
  • Right Click on Prevent Installation of Devices not described by other policy settings and edit this option, set it on ENABLED.
  • Reboot Windows and enjoy its inability to pollute your system with its standard driver, open gpedit.msc again and revert the change so you will be able to install your driver.

For laptop Asus X82S using Windows XP, I was successful using these steps

Please go to C:\Windows\System32\Drivers\.... You will see some files start with kb, change kbfiltr to kbfiltr_del. And you will have done it.

This will disable laptop keyboard. At the moment, I use USB keyboard. And no problems for keys anymore.

Installing a proper driver through device manager worked fine for me.

I have an acer. All I did was click the option which let me choose from a list of drivers. I installed a toshiba japanese driver and shutdown the laptop. When started back up, the keyboard did not work at all. (P.S.: I did not restart; I shut it down.)

I solved my similar problem by clicking Start>Devices and Printers, then clicking on the icon for the computer and clicking the Hardware tab in the Properties dialog. Then I double-clicked the keyboard entry to open the Driver Properties dialog and clicked the Change Settings button, which should require administrator privileges. Once that dialog opens, click the Driver tab, and the option to disable the driver should be available. Click disable and bingo, laptop keyboard all gone away. Make sure you have you USB keyboard installed properly first.

Worked first time for me.

Open Device Manager in your laptop.
Expand the Keyboards section.

You might be seeing this (if you have not yet connected the external keyboard) :-

enter image description here

The keyboard arrow marked in red is the inbuilt keyboard your laptop has. (Your laptop's keyboard might have a different name)

Now connect your wireless keyboard.
You will see another keyboard added under the keyboards section in device manager (arrow marked in green).

wireless keyboard

Again, your wireless keyboard would have a different name than mine (mine is wired). This is just an example.

Now right click on the inbuilt keyboard and click 'uninstall' (marked with red arrow).This will disable your inbuilt keyboard.
Do not panic as the inbuilt keyboard's drivers would be reinstalled as soon as you restart the machine. However, uninstall the inbuilt one only after you have plugged in your wireless one.
