Keyboard failure WIndows 7 keyboard failure

Wireless keyboard for previous versions of Windows shoudl work with windows 7. If won't work, no way. to repair them. You might try to take it to a shop but better buy a new one

plug in a usb keyboard and see if that works, then reset bios to default, reboot. if that doesn't work then possible hardware damage eg liquid damage, droped etc

Yes you probably pulled out the cable. Take your keyboard back out and look for a small flat cable that runs under the palm rest.

You will need to update the drivers on the computer for the docking station. It will be the windows seven drivers or lack of them that is causing a failure to remap the usb ports that the wireless dongle is plugged into.

You can do the following: try a generic USB keyboard if it works then try your keyboard in another computer running windows 7, so that you will know your keyboard is fine. If so then your windows 7 installation has suffered somehow..
P.S. Sometimes a virus can cause a keyboard or mouse to malfuntion.

The keys on this board are not able to be disabled. You could try re-installing the correct drivers for it: https://www.microsoft.com/accessories/en-au/d/wireless-keyboard-800
Or Resynchronize the keyboard with the receiver. https://support.microsoft.com/en-au/help/838398/troubleshoot-response-failures-in-wireless-keyboard-or-mouse
If both of these steps fail your keyboard is likely faulty.

Hi, by reading your question I am not sure if you are saying that when you load up Windows 7, nothing shows but a black screen or if your keyboard is not working. Well anyway I am going to try and help with both.
If you are getting a black screen when loading up, this is probably because your computer does not support Windows 7. In order to use Bootcamp and install Windows 7 you must be on Mac 10.6 and up or Snow Leopard. That is the only OS that supports Windows 7 and if you do have Mac 10.6 but you still have the black screen it is probably because the actual computer can't handle it or the drivers in the computer might not support it. I would say anything before 2005 will not be able to load Windows 7, but I am just taking a guess. For my second solution dealing with your wireless keyboard, when you installed Windows 7, no drivers were installed because Windows does not support them yet. This is why your keyboard was blinking, it was looking for a connection because it was not connected to anything. When installing Windows 7 you will need a wired mouse and keyboard because your Apple Wireless Bluetooth Keyboard is not yet pared with the computer. In order to install the drivers to make your keyboard work you need to load up Windows 7 by holding down the "option" key when turning on the iMac. Then once you select Windows 7, and it loads up to the desktop you need to insert your Mac reinstall CDs, then follow the on screen steps to install the drivers. From there you should be able to go into the control panel and add a wireless keyboard under the devices panel.
I hope this helps, Justin

Windows 7 is different, get used to it. Your old keyboard is probably not supported.
