SYMPTOMS
When you press the Sleep hot key on a Microsoft keyboard, the computer may stop responding (hang).

This behavior occurs if the following conditions are true:
 * A device in your computer is not working correctly.
 * You put the computer in standby mode, wake the computer, and then press the Sleep hot key.



CAUSE
The Human Interface Device (HID) is not configured to wake the computer when you press a key on the keyboard or mouse.

This behavior occurs if the basic input and output system (BIOS) that is installed in your computer reduces power to the port where the input device is connected.

Note You may not be able to use Bluetooth devices to resume operation from certain power management states (such as suspend or hibernate). In certain low-power states, the wireless transceiver may not be able to receive information from Bluetooth devices.

For more information about how your system resumes operation, see the documentation that came with your computer or contact the computer manufacturer.



Connect the keyboard to both the universal serial bus (USB) and the PS/2 ports

 * 1) Quit all programs, and then turn off the computer.
 * 2) Plug the PS/2 connector on the Natural Keyboard Pro into the PS/2 port on your computer.
 * 3) Turn on the computer.
 * 4) Plug the USB connector on the Natural Keyboard Pro into the USB port on your computer.
 * 5) Install the Microsoft IntelliType Pro software.

Use Device Manager to troubleshoot possible hardware configuration problems on your computer
In Device Manager, look for marked problems with devices. If there is a problem with a device, it is listed in the hardware tree under Computer.

Additionally, the problem device has a symbol that indicates the type of problem, for example a black exclamation point (!) on a yellow field indicates the device is in a problem state. Note that a device that is in a problem state can function.

A red X indicates a disabled device. A disabled device is a device that is physically present in the computer and is consuming resources, but does not have a protected-mode driver loaded.

A blue i on a white field on a device resource, in Computer Properties, indicates that the Use Automatic Settings feature is not selected for the device and that the resource was manually selected. Note that this does not indicate a problem or disabled state.

At the top of the property sheet, there is a description of the device. When you click the Resource tab, the window in the middle of the tab indicates which resource types are available for the selected device.

The list box at the bottom contains a Conflicting Device list. This list indicates a conflict with an error code. If any devices are listed as having a conflict, disable the devices in Device Manager. To do so, follow these steps:
 * 1) Double-click the branch that contains the device that you want to disable, click the device, and then click Properties.
 * 2) On the General tab, click to select the Disable In This Hardware Profile check box, and then click OK.
 * 3) Restart your computer

If no devices are listed as having a conflict, follow these steps to disable devices in Device Manager:  Click Start, and then click Control Panel. On the Hardware tab, double-click System, and then click Device Manager. On the Device Manager tab, disable all devices under the following branches:  Display adapters Floppy disk controllers Hard disk controllers</li> Keyboard</li> Mouse</li> Network adapters</li> Ports</li> PCMCIA socket</li> SCSI controllers</li> Sound, video, and game controllers</li></ul>

To disable a device in Device Manager, follow these steps: <ol style="list-style-type: lower-alpha;"> Double-click the branch that contains the device that you want to disable, click the device, and then click Properties.</li> On the General tab, click to select the Disable In This Hardware Profile check box, and then click OK.</li> Restart your computer.</li></ol> </li> If the problem is resolved, enable the devices that you disabled in step 3, and then verify that no devices are conflicting.

Note Enable devices in the following order: <ul> COM ports</li> Hard disk controllers</li> Floppy disk controllers</li> Other devices</li></ul>

To enable a device and look for possible conflicts, follow these steps: <ol style="list-style-type: lower-alpha;"> Double-click the branch that contains the device that you want to enable, click the device, and then click Properties.</li> <li>On the General tab, click to clear the Disable In This Hardware Profile check box.</li> <li>Click the Resources tab, and then verify that there are no conflicts listed under the Conflicting Device List.

Note that the Resources tab does not appear for each device.</li> <li>Click OK, and then restart your computer.</li></ol> </li></ol>
