Windows 7: Trying to Uninstall PS/2 Keyboard

Trying to Uninstall PS/2 Keyboard

In December 2010, I spilled water on my computer and that caused the keyboard to malfunction. Since then I have used 2 different wireless keyboards with great success. The issue is that my old keyboard still types things when I put pressure on certain keys and it is on my last nerve.

I uninstalled it on Device Manager but then Device Manager recognized it again and the computer reinstalled the driver. I have a Toshiba T135-S1305 running Windows 7. If you need anymore information from me, please let me know. Thanks in advance.

Windows 7 Home Premium 32 Bit SP1
 
 

Hi Karlsnooks. I have attached my "Mysystem.txt" file for you to look at.

In regards to your instructions, I could not choose disable so I chose uninstall. Then it asked me if I wanted to restart. I did not restart but I shut down like you told me to. So I turned the computer back on and it booted up and when it got to the sign in screen I tried to use the keyboard I was trying to uninstall and it still worked so, no, my problem was not fixed.

I don't know if this is important or not, but the keyboard I am trying to uninstall is a keyboard built into the laptop. Would I have to take it out physically?

I hope this helps

Eric

while I study some of the data in the mysystem.txt file, please add info into your system specs so that others will know about your system.
Be sure to add the SP1 to the operating system info.

Here is a write-up to guide you.Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec
(left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Ř Manufacturer and Model OR Custom build.
Ř ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

With Speccy, you can select with your mouse/touchpad info from the display
and paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

Eric,
I've never done this myself, but you can try:
Boot up into safe mode
go to a command prompt
carry out following commands:
cd /d c:\window\system32\drivers
ren kbdclass.sys kbdclass.ysy
exit

shutdown
Power up

So I booted up into Safe Mode without networking and launched a command prompt. Was I supposed to choose "Safe Mode with Command Prompt"?

Anyway, I typed in the cd command and it changed directories like it was supposed to. Also, I put in "c:\windows" not "c:\window." Then I typed in the second command and it said "Access is denied."

I then shut down and powered it up again and the keyboard is still typing. I'm assuming the problem lies in the "Access is denied" response. Any help would be appreciated.

The keyboard is damaged. It needs to be replaced. While it is still connected it will be found by the system. You could try pulling the cable that connects it to the mother board but I'm not sure whether your wireless kybd will be recognised at bootup so you can login. Worth a try though.
Otherwise get a replacement keyboard. Water is not good for keyboards.

Yeah all I had to do was take the keyboard connector out of the computer and voila! it doesn't work. I couldn't be happier.

Thanks for the help and attempted help
