SYMPTOMS

After you install Windows on a computer that has a Microsoft Natural Keyboard Pro keyboard attached (Device Manager identifies it as a "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard"), some of the Internet, multimedia, e-mail, and programmed hotkeys across the top of the keyboard do not work.

If you start the Keyboard tool in Control Panel, click the Hardware tab, click Properties, click the Driver tab, click Update Driver, click Show all hardware for this device class, and then click the Microsoft Natural Keyboard Pro driver, you receive the following warning:
Installing this device driver is not recommended because Windows cannot verify that it is compatible with your hardware. If the driver is not compatible, your hardware will not function correctly and your computer might become unstable or stop working completely. Do you want to continue installing this driver ?
If you click Yes, the drivers are loaded. After the required reboot, the keyboard and mouse no longer work.

CAUSE

The "Microsoft Natural Keyboard Pro" updated driver description is misleading. This driver is intended to be used solely with the Universal Serial Bus (USB) version of the Microsoft Natural Keyboard Pro keyboard. Even though your Microsoft Natural Keyboard Pro keyboard has both a PS/2 and a USB connector, the keyboard itself is i8042-port-based, while the USB connector is strictly for the built-in USB hub.

Installing the incorrect driver disables the i8042prt port and enables Human Input Device (HID) support, which does not work with this keyboard.

RESOLUTION

To re-enable the keyboard, use any of the following methods.

First, try the Last Known Good Configuration option by pressing F8 at the boot menu. If the Automatic Logon feature is enabled on this computer and has already logged on a user and there is no keyboard or mouse functionality, use one of the following procedures:

Use Recovery Console

  1. Boot the computer from the Windows installation media and press F10 when you see the "Welcome to Setup" screen to start Recovery Console.
  2. Type "cd \system32\drivers" (without the quotes) and press ENTER.
  3. Type "ren kbdhid.sys kbdhid.org" (without the quotes) and press ENTER.
  4. Type "copy i8042prt.sys kbdhid.sys" (without the quotes) and press ENTER.
  5. Quit Recovery Console by typing exit. This causes a reboot.
  6. Log on as an administrator and reinstall the regular "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard" drivers by starting the Keyboard tool in Control Panel, clicking the Hardware tab, clicking Properties, clicking the Driver tab, and then starting the Update Driver Wizard.

    NOTE: You will not have mouse functionality until you reload the correct keyboard driver and restart the computer.
  7. Install the full Microsoft IntelliType Pro version 1.1 update or later drivers for Windows 2000 that support the Microsoft Natural Keyboard Pro. These new drivers are available on the Microsoft Web site, and once installed activate the hotkeys across the top of the keyboard.

Remotely Edit the Registry

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

How to back up and restore the registry in Windows

If the computer is connected to a network, you can remotely edit the registry as follows.

NOTE: If the computer is networked but is not part of a domain, you may need to map a connection to the computer's IPC$ share by using that computer's local administrator credentials before you can attach with Regedt32.exe as described below. To map a connection to the computer's IPC$ share, use the following command:
net use \\remote_computer_name\IPC$ /user:administrator *
To remotely edit the registry:
  1. From another Microsoft Windows NT-based or Windows 2000-based computer on the same network, run Regedt32.exe.
  2. On the Registry menu, click Select Computer, and then type the computer name of the computer that has no keyboard or mouse functionality.
  3. After you connect, click Hkey_Local_Machine on Remote_Computer_Name on the Window menu, and then navigate to the following key:
    System\CurrentControlSet\Services\i8042prt
  4. Double-click the Start:REG_DWORD:0x4 value, and then change it to 0x1.
  5. Navigate to the following registry location:
    System\CurrentControlSet\Services\kbdhid
  6. Double-click the Start:REG_DWORD:0x1 value, and then change it to 0x4.
  7. Navigate to the following registry location:
    System\CurrentControlSet\Enum\ACPI\PNP0303\4&2658d0a0&0
  8. Click the 4&2658d0a0&0 key, click Permissions on the Security menu, and then grant Full Control permissions to the Everyone group. Click Apply.
  9. Double-click the Service:REG_SZ:kbdhid value, and then change it to i8042prt.
  10. Click the 4&2658d0a0&0 key, click Permissions on the Security menu, and then remove Full Control permissions from the Everyone group. Click Apply.
  11. On the Registry menu, click Close.
  12. On the Registry menu, click Exit.
  13. Restart the computer that has the mouse/keyboard problems. After the computer restarts, the mouse and keyboard should be functional.
  14. Install the full Microsoft IntelliType Pro version 1.1 update or later drivers for Windows 2000 that support the Microsoft Natural Keyboard Pro. These new drivers are available on the Microsoft Web site, and once installed activate the hotkeys across the top of the keyboard.
NOTE: When the PS/2 plug of the keyboard is plugged in, it is a PS/2 keyboard (as stated), but the keyboard is capable of a Universal Serial Bus (USB) only mode. If only the USB plug is plugged in, it is both a USB hub and a USB keyboard.
