Question about Microsoft Wireless Laser Mouse 5000

4 Answers

Erratic pointing My Mouse 5000 has begun to point very slowly and erratically; sometimes the pointer refuses to move at all. Also the red "light" or "laser" that was visible on the underside is out. Are the two conditiosn related and how do I fix?

    same problem, going to try yooperbud's solution

    Yooperbud, did you read the problem. It is the mouse. Not the keyboard or printer. I have the same problem. This mouse is horrible. As for the light, it is an invisible laser on the 5000. So, there is no light. Just a horrible mouse.

    Vertical movement is more erratic than horizontal. A patterned mouse pad helped, but not enough.

After experiencing the same issue for a few frustrating hours, I read here the theory about the required distance accuracy between the sensor and the surface.I used to be able to use mice (any brand) on a simple piece of paper or directly on (wooden) surfaces. Not with this "laser mouse..." I was about to try the "tape-with-a-hole" solution, but before trying that I simply threw a heavy, thick magazine with a glossy back-cover on the table and tried again. Worked like a charm. The heaviness of the magazine (I think) lent the "flatness" which I believe is the real required solution. I'm not sure if the glossiness played a role here...

I hated this mouse ever since I got it. My old optical mouse would work on any surface, but this one would not. On most surfaces that I use, it was horribly jerky.

After a lot of aggrivating hours of using this mouse, I discovered that the problem is that this mouse is Very picky about the distance that the laser sensor is from the surface that it is being used on. If you use the mouse on a surface that is not perfectly flat, it is really jerky.  If you use this mouse on your pants leg or other curved surface, the surface gets too close to the sensor. The laser light is reflected at an angle that doesn't hit the sensor.

My 2 cent fix was to take a few layers of Scotch tape, punch a hole thru them about the size of the laser hole, and then put the tape on the mouse, lining up the holes. Try to use just enough layers of tape to match the thickness of the 4 oval glide pads on the bottom of the mouse. My mouse now works perfectly.

Microsoft should have put a glide pad around the sensor hole, instead of putting the silly the "Microsoft Laser Technology" sticker there.

If the tape doesn't last, I might pilfer a glide pad from one of my old mice, and drill a hole through it.

Go to Control Panel and click on Keyboard. Keyboard properties will appear, then click on SPEED tab, adjust the various items as you desire. Also the printer properties has tabs to set your keys to function as you would like them to.
Hope this helps. Bud

Not sure what you mean but a possible problem with erratic mice is the mouse pad. A coloured pad sometimes reflests the light in an erratic fashion that causes the pointer to do unexpected things. Try it without a pad or one with no patterns.

Microsoft has a knowledge base article on erratic mouse pointer movement that may help. As you can see in this article, there is more to it than uninstalling and reinstalling the mouse driver. Microsoft Support on Mouse Problems.
As I've said, it's possible that something has corrupted your mouse driver. You can either 1) re-install the driver, or 2) roll back the driver. Either one of these may help. To roll back your driver in Windows XP, go to Start --> Settings --> Control Panel --> Mouse. Click on the "hardware" tab. Select the appropriate pointing device, and click "properties." Click the driver tab, then select "roll back driver."
Under the "hardware" tab, there may be more than one mouse. If this is the case, select the one that is not used, follow the settings above, and then select "uninstall." Or, you can go into Control Panel --> System --> Hardware --> Device Manager, and remove the device under "Mice and other pointing devices

Mouse point has it's own mind.

If it's an older style mouse, it might just need cleaning. If it's optical, sorry, I have no ideas.

When this behavior is observed when using a Logitech product withinWindows® XP, it may be caused by a feature within Windows called"enhanced pointer precision". This feature may conflict with Logitech's software, causing the erratic movement. Enhanced pointerprecision became available in Service Pack 2 and therefore is notapplicable in any version of Windows® XP without Service Pack 2installed. For more information on enhanced pointer precision,please click HERE. If this link does not work, then you should go to Microsoft and search for Knowledge Base article 895550.

Please see these articles from the Logitech database for possible troubleshooting tips as well:
