Hi folks,
Well first make sure the batteries in the wireless keyboard have enough power.
Also, because it is a wireless keyboard, there is possibly an issue with latency, ie how much time it takes for a packet of data (a series of keystrokes) to get from one designated point to another.
The wireless medium itself introduces some delay. The size of the packet introduces delay in a round trip since a larger packet will take longer to receive and return than a short one.

My point is there is already the wireless medium to consider. If you then couple that with the settings to which the keyboard is configured (In keyboard, in Control Panel, or maybe the software that was installed from the disk that came with the mouse/keyboard), eg Keystroke repeat rate, keystroke repeat delay etc. then the process has a capacity to falter.
I would put the Repeat Delay for the keyboard at about 2/3's and experiment with the Repeat Rate in case that makes a difference.

As for setting it as the 'default' keyboard, I'm not exactly sure about whether that would make a difference, and I also don't know if it is possible to set it that the laptop 'completely ignores' the original keyboard, as I'm sure the CMOS needs to detect a keyboard on bootup, in order to proceed. USB/wireless keyboards, I imagine, are 'loaded' after this point, so if you actually 'disabled' the original keyboard (in order to stop it possibly causing error), there is a chance that the laptop would not boot in the first place. This is just a theory of mine, however..

I would play with the sensitivity (keyboard repeat rate and delay) and make sure your batteries are juiced up.

I guess you could scan, fix and immunize with Spybot, just in case there is a malware issue there too.. Just a remote possibility..
I actually have a wireless Belkin keyboard and mouse somewhere, I'll look them out and check the software configs, and see if I can give you any more ideas. The software that came with the keyboard and mouse would be the place to start, to make them 'sort of default', in the sense that system resources would be more prioritised in their favour. Have a look in that software, and I will do the same and post here if I come across anything.

Hope this helps

Mouse didn't detected


Touch pad usb or wireless mouse ?
Laptops use the convenient touchpad and integrated scroll mouse that allow you to use just your finger to navigate Web pages, documents and open files and programs. Just like all other hardware, the laptop's integrated touchpad and mouse can experience errors and problems that cause you to lose functionality for a length of time. Whether the laptop's mouse is not working because of internal errors or conflicts with another device, several "tricks" can work to restore it.

Locate the function "Fn" button on your laptop in the lower left corner of the keyboard. Look in the keyboard's upper row (the F1 through F12 buttons) for an icon of a touchpad or computer mouse. This keyboard button acts as the toggle switch to enable and disable the built-in mouse and touchpad function. Press and hold the "Fn" button together with the mouse icon button. Look for the disable/enable symbol that briefly displays on your screen. Slide your finger over the laptop's mouse and attempt to use it as normal. Press the Windows keyboard key if using Windows 7, type "main.cpl" in the search box and press "Enter." Press the left arrow key to navigate over to the "Device Settings" tab. Press the tab key to reach the "Enable" button in this section. Press "Enter" on your keyboard. Press the tab key to reach the "Disable internal pointing device" check box. Press the space bar to remove the check mark. Put your finger on the touchpad, and move the pointer down to the "Apply" button. Click "Apply" to save the settings. Close the mouse "Properties" box. Press the keyboard "Windows" logo key to open the "Start Menu." Press the arrow keys on your keyboard to navigate to the "Shut Down" or "Turn Off Computer" menu. Press the up or down arrow key to highlight "Restart." Press "Enter" to restart your computer and attempt to use the laptop mouse as it should normally function. Open the "Control Panel." Go to the "Add and Remove" or "Uninstall" programs section. Highlight any secondary mouse devices in the list that you have installed for your laptop, such as an external USB mouse. Select the "Uninstall" option to remove any software and settings associated with this secondary mouse. Restart your computer and attempt to use the built-in laptop mouse as normal. Check to see if the mouse is working properly. Press the keyboard's "Windows" button to open the "Start Menu." Press the keyboard's arrow keys, "Enter" button and "Tab" to navigate to and open the "Control Panel." Go to the "Hardware and Sound" section, and press "Enter." Navigate to "Device Manager," and press "Enter" to open it. Find "Mice and other pointing devices from the list" and open its "Properties" dialog box. Select the "Driver" tab and choose "Update Driver." Allow Windows to search the Internet for drivers and to update them automatically. Restart your computer after the drivers are updated, and use your mouse as normal.

How to troubleshoot keyboard issues?


Wireless Keyboard:
If only some of the keys don't work skip to the section Some Keys Don't Work below.
  1. Resynchronize the keyboard. Press the connect button on the keyboard for 5 seconds. Then press the connect button on the receiver for 5 seconds
  2. Change the batteries.
  3. Try reseating the receiver if possible.
  4. Try positioning the keyboard closer to the receiver.
  5. Skip to the section Generic Troubleshooting below.
Some Keys Don't Work:
  1. Check if any of the num lock key, shift lock key, etc are causing the issue. This is especially prevalent on laptops which don't have a distinct numeric keypad.
  2. If it's only the multimedia or hotkeys that don't work then try installing the specialized multimedia keyboard software that came with the system/keyboard.
  3. Try reseating the keyboard and rebooting.
  4. Go into Accessibility Options in Control Panel and check that Sticky Keys, Filter Keys and Toggle Keys are all switched off.
  5. Check if the problem occurs in the BIOS. A good screen to test with is the create BIOS password screen if the keys don't work here then a new keyboard is in order.
  6. Continue on to Generic Troubleshooting.
No Keys Work:
  1. Try reseating the keyboard and rebooting.
  2. Try power draining the system. This can be particularly effecitive with a laptop.
  3. If this is USB try a different port.
  4. Try entering BIOS - if you cannot get into BIOS then the keyboard probably needs to be replaced.
  5. Go on to Generic Troubleshooting below.
Generic Troubleshooting:
  1. Try uninstalling and reinstalling the keyboard driver and reboot
  2. Try system restore back to before the problem occurred
  3. Check for malware or 3rd party software that may be interfering with the function of the keyboard.

Lost keyboard driver


Go into device manager, it should show a list of drivers on the computer, next look for the keyboard, click on the + now! right click on the second line, see if keyboard has been disabled, if yes! enable it that should restore key function, do the same with the mouse. Note you may have more than one line, just make sure all lines in the keyboard and mouse are enabled.

Compaq notebook laptop: my mouse pointer or arrow is


If you have a manual for the notebook, check to see if you can use the function key and the similarly coloured key on the keyboard which enables/disables the touch pad. Usually you can disable the mouse pointer touch pad with this FUNCTION key + MOUSE key when pressed together. Often these keys have the same colour (usually blue). The purpose is to disable the touch pad when you are using an external USB or wireless mouse, then you press the 2 keys again together to enable the touch pad once you have removed the USB/wireless mouse.

If that doesn't work, borrow a USB mouse and attach it to your notebook to use temporarily while you diagnose the problem.

Another keyboard skipping until I removed the dead battery, now it works.


Turn off the touch pad mouse, there is a button to do that. If the problem is still present then remove the mouse driver and go to Synaptic web site and download the most current driver. HP is the place to get the driver though. For some strange reason the problem is present more under XP than it is under Vista. On a Vista the problem is fixed. Either you can disable it or use external USB mouse instead.
