Registry Delete - Keyboard Resource Conflict Error

My keyboard on my laptop will not work. It says it has a Code 12 error that there are not enough resources available to run the program. Specifically, my PS2 Keyboard (the internal keyboard on the laptop) and the touchpad are competing for the same resources, so I cannot reassign one of them.


I have a Satellite A 105 - S4344 Laptop with Windows XP. Last week it got a trojan virus and the computer shut down. I finally managed to open it in safe mode. I ran the antivirus system (Symantec Antivirus) and it said it removed the files. Unfortunately, it appeared to have also removed the driver for my dvd player (Matshita UJ841S).

I found advice online that suggested deleting the upper and lower filters from the registry:

Click Start-->Run and type regedit and click ok. On the left hand side, navigate to:

However, I stupidly and overeagerly deleted the upper and lower filters from 966 instead of 965. :)

Now, my keybaord and touch screen do not work.

I do not have an external keyboard, but I do have an external mouse, so using the external mouse I checked on device manager. The keyboard had a yellow exclamation mark, and says it has a Code 12 error that it does not have enough resources.

I looked at the resources the keyboard is using - it has 3 listed, but apparently I/O 6060 and 6064 are being used by my touchpad. hoewver, when I look at the touchpad resources, it tells me that those same resources are being used by the keyboard, and that neither keyboard nor touchpad is getting enough resources to work.

The same results in safe mode. Also, the keyboard and mouse work fine until windows loads. I have tried restarting in last known good configuration, but no luck.

I have no idea how to proceed. Also, my keyboard will sometimes work for about 3 minutes after I get into windows before it dies, so I might be able to try one or two things, but only if it requires minimal typing.

any ideas? or do i just have to get this thing reformatted?

Hi rugbybruised welcome to Geeks to Go.

Lets see if we can get this fixed.

Did you try a system restore?

Next, all of your drivers can be found HERE
You will want to refine the search. Choose your OS (XP or XP with SP2/SP3).
You can then choose the category to slim down the choices.

I only found a DVD Rom driver and a Touchpad driver.

We may have to install the Chipset Drivers for the Board

First of all, optical drives don't need any extra drivers in XP.

Try system restore form recovery console:

If you have Windows XP CD...

1. Boot from the CD.
2. When the text-based part of Setup begins, follow the prompts. Select the repair or recover option by pressing R:

3. You'll find yourself at this screen:

Posted Image

4. Once you are at the Recovery Console you will be given at least one choice of Windows installations. Normally the choice you want is the number 1 choice. Click the number 1 key at the "top" of the keyboard and click enter.

NOTE: at this point your numbers to the right of your keyboard are turned off. If you insist on using these keys for your numbers remember to hit the Numbers Lock key before clicking a number over there or your computer will automatically reboot and you will have to wait through the previous steps to get back to the console.

5. You will be given a message asking for the administrator password. Unless someone or something has messed with your computer there is no password so you just click the Enter key.

6. This will bring you to a prompt that says:


7. Type:

cd \

Press Enter

Note: between "cd" and "\" there should be a "blank space" otherwise the command won't work

8. The prompt should now say:


9. Type:

cd system~1\_resto~1

Press Enter.

Note: If it gives an error "Access Denied" while accessing the folder, follow the method below

Type: cd \

Press Enter

Type: cd windows\system32\config

Press Enter

Type: ren system system.bak

Press Enter

(note the spaces between ren and system, and then between system and system.bak)

Type: exit

Press Enter

now the computer should restart, then follow steps 1-6

10. Type:


Press Enter

NOTE: When you hit enter it will list all the restore points folders like "rp1", "rp2" we have to see the last restore point to copy the file from a recent backup. If the restore points have more than one page then you have keep on hitting the key to view the last restore point folder.

NOTE: It is a good rule of thumb to choose the files from the restore point folder which the second to the last one.

11. Type:

cd rp{with the second to the last restore point number }

Press Enter

Example: cd rp9. if rp10 is the last restore point

12. Type:

cd snapshot

Press Enter.

NOTICE: Now the command prompt will look like this:


Note : restore point 9 assumed for clarity of the content.

13. Type:

copy _registry_machine_system c:\windows\system32\config\system

Press Enter

14. Type:


Press Enter.

Final note : If the above procedure won't solve the problem, repeat all steps, but in step 13 type:

copy _registry_machine_software c:\windows\system32\config\software

Alternatively, select different restore point.

If you don't have Windows CD...

Download Windows Recovery Console: http://www.thecomput...om/files/rc.iso
Download, and install free Imgburn: http://www.imgburn.c...hp?act=download
Using Imgburn, burn rc.iso to a CD.
Boot to the CD...let it finish loading.
When the "Welcome to Setup" screen appears, press R to start the Recovery Console.

Follow steps 3 - 14.
