Microsoft Wireless Desktop 4000 receiver quit working

I'm on my second 4000 and I'm suddenly having the same issue as the first. I was typing and using the mouse and suddenly the lights on the receiver started flashing, then stopped with two lit. Nothing worked, so I rebooted and now the receiver doesn't appear to be working at lights, etc. I've tried every USB slot on my dock and laptop, and rebooted a number of times to no avail. Is this a known issue, and is there any way to get it working again?

Make sure that you have no other wireless devices nearby. I had a similar issue and it was because of a cordless phone I was using. Switched the phone to 5.8GHz and problem with sync was solved.

They need to be re-synced. Sometimes the wireless signal from the keyboard/mouse is broken and the receiver cannot find it again. A quick re-sync always fixed the problem for me.

After using my Microsoft Wireless Comfort Keyboard 4000 for about 20 minutes, keys stop working in the middle of use. Current drivers are installed, fresh batteries have been used, I have uninstalled and...

Chances are that the keyboard is too far away from the receiver. This will wear the batteries down very fast. Optimal distance is less then 3 feet away unobstructed. try this and you shouldn't have many problems anymore.

Wireless mouse stopped working.

Unplug the wireless receiver from the back of the computer. Wait 10 seconds and replug back in. Check connectivity. If nothing then check batteries in mouse, if still nothing try click the Connect button on the wireless receiever and then underneath the keyboard...repaet the process for the mouse. You should get something on the screen stating the channel 1 is for the keyboard and channel 2 is for the mouse. Hope this helps! - Erick :-)

I have microsoft bluetooth optical mouse 4000 it suddenly stopped connecting to the receiver, as I cannot move mouse anymore

Just to clarify, this is a wireless optical mouse, right? Please try the steps below:

1. Use fresh batteries.
2. Make sure that the mouse is turned on.
3. Check if there's a connect button on the wireless receiver and underneath the mouse. If there is, try holding down the two connect buttons at the same time for five seconds and then release them both.
4. Try moving the mouse.
5. Make sure that there are no possible wireless interference between the wireless receiver and mouse like the base of a cordless phone, cell phone etc.

If same problem occur after doing the steps below, then you may want to contact the manufacturer for RMA. This Microsoft 4000 has a three year limited warranty.

Thank you!

Microsoft 4000 Keyboard

Start simple - unplug and replug the cord that connects the keyboard to your computer. Try typing again. If it still does not work, restart your computer. If it still does not work after restart, go to Microsoft's website, and redownload the drivers/software for the keyboard. Good luck!

Keyboard not functioning properly

I had a similar problem with a new MS 4000 Keyboard. I found that I had two versions of the IntellPoint software on my Vista system. I uninstalled the older version (which came with my new computer) and the keyboard seems to be working well now. Check your system via the Control Panel, Install/Uninstall Programs and look for the MS IntellPoint software. Good luck.

Dear Nealteresa:

Please click on the link below and download the drivers for Microsoft Wireless Optical Desktop 4000 and select IntelliPoint 6.2 (32bit) for Windows Vista. Or you can also customize by selecting product and operating system. Note: However the Microsoft Wireless Optical Desktop should work with the native drivers of operating system.
