Mouse cursor moves by its own against my will (acting like a spring)

Well, as you told me your self, things had worked for a week afterreplacing some hardware parts.. Could you please tell me in a week or so, if it still works.. then i would do this on my own computer to test it and hopefully, this is the 100% fix.. there is a lot of others out there wanting this same solution..

I know there are quite a few people looking for a solution, which is why I'm saying not to jump to conclusions! :smileywink:  I'll let you know in 2, perhaps 3 weeks to see if it is the real deal.  It wouldn't hurt to try it yourself on your own notebook, then you would know too!  In fact, I'd like to see more people post because like any good scientist will tell you, the more data you have the better.

back again... it seems that a couple of us have stumbled onto a solution. mine was similar to tightening screws inside the case... so here you go, keep in mind i'm not recommending this, just saying mine has been working fine for a month or so now.

-- remove keyboard
-- grasp both ends of the keyboard and twist approx. 20deg in each direction from normal
-- hit the top and bottom sides of the keyboard 'firmly'
-- place the tip of a flat screwdriver under the pointstick housing on the back side of the keyboard, twist and pry upto but not past the point of permanent deformation
-- replace keyboard

after speaking with another dell tech and asking if there had been any official resolution to this problem yet AND explaining what i had done to fix the issue on my laptop, she still insisted that it was a driver issue not a hardware issue... what can you say, they must know a lot more than me.

(Running: Inspiron 8100, WinXP Pro, Replaced Mobo from Latitude C810, Inspiron 8100 bios)

By the way, prior to the brute force method for fixing this problem, it existed in XP Pro, Redhat 9, and Mandrake 10. All dell techs I mentioned this to still insisted it is a driver issue.

Ok, i got the very same answere from Dell to.. it must have been the drivers they say.. a repair guy from dells service company came by and he had a computer similar to mine.. he also had this same error.. and he told Dell's people, but still they said this was a driver error.. and he had been trying Knoppix, windows and had the same error.. he also had tried several driver versions.. ..

Does anyone know other computers (other brands) with the same pointing stick installed and if they have the same problem?

I did what freeflier said in his last post (about: removing keyboard, twist etc.) So far it is working well today. I tried to apply pressure to the palmrests and bending the whole housing of the laptop and it is working good.

If I don't post back again in a week or so, consider freeflier 's fix is working on my latitude c610

=)

Good morning!

I fixed my c600 mouse problem by literally blocking connection between pointing stick and mainboard.
Here is how I did it: http://nativeland.kolhoos.ee/stories/storyReader$497

Now after week of using, my touchpad is working without any problem.

Take care,
Priit

Hi!

You are right if you prefer pointing stick, can't help you. However, I use touchpad and now without pointing stick I can use touchpad without any single problem (just disabling it didn't help much).

So, I wish good luck to anybody who is fixing this pointing stick problem because you can only imagine how many nerves it all has got already... :-)

Take care,
Priit

I formatted C: clean install of XP pro, SP2, bios is PS/2 + touchpad. I did not update Synaptics driver or software - what is installed is stock from XP or Synaptics TouchPad v5.6 (version 7.2.12 March 17,2003. I have now run for many hours and the cursor is not wandering now. Note that my stick pointer is not working therefore disabled by what I dont know. I assume it is the version of Synaptics or it is dead and has always been the source of the problem. Also if I used a USB mouse in the past I would have the cursor problem so far it is ok with external USB mouse attached.

Freeflier--thanks for your solution.  It will be the next thing I try if the keyboard tightening does not work.

Is there any way that you can post a rough illustration or photos if you get the chance?  I wanted to be more specific on a couple of points in your instructions:  like when you say "top and bottom sides," do you mean the edges of the keyboard or the plastic/metal sides?  And I'm not quite sure what you're talking about regarding the pointstick housing; I'm sure if I were looking at the keyboard I could get a better idea.
