Question about Microsoft Wireless Laser Desktop 4000 Keyboard/Mouse

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 all...no 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?

    Re-syncing is not the issue. The receiver flat out doesn't work - no lights, etc. Pressing the sync button doesn't make anything happen...

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.

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 Hardware website Support/Downloads Sections.

Click this link maybe is ok for you.

(The closest I could find to yours was the "Wireless Ergonomic 4000" so maybe u need to change regions on the website?)

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.
