Re: Precision M6500 touchpad jumps left a few inches when moving finger right

Great about the new hardware.

So how does one insure that the next repairman will be installing the new improved hardware, or another old one?

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

I forwarded one of the recent postings of this forum to the people at Dell (who were involved in resolving my issues) this morning.  They were quite thankful for my info and said in their reply:

1)      “We will get this over to our Community Outreach Team so they can get engaged in the forums regarding this issue and get these customers taken care of”

2)      “We will get the depot engaged to make sure they are using the new stock of parts”

So there are people at Dell who are well aware of the issue and will work toward resolving this.

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

I don't want to be the bearer of bad news, but I just had my palmrest/touchpad and keyboard replaced 10 days ago and still have the problem. This was the first replacement of the keyboard and the third replacement of the palmrest/touchpad.

I have examined the replacement parts along the way and have detected no change whatsoever in the design of the palmrest (my machine is now on its fourth). The replacement keyboard was of a different design but unfortunately it did not solve the problem.

I have discovered that I can influence the problem by applying pressure to different areas of the plastic strip of the palmrest that is above the top of the touchpad and below the upper set of mouse buttons. I discovered this before I realized that directly beneath this plastic strip is where the keyboard plugs into the touchpad. When the problem presents itself and the left third of the touchpad becomes unresponsive, I can cause it to become responsive again by applying light pressure to the plastic strip at the point where the dead/live transition line exists. This solution works as long as I'm willing to work one-handed, which isn't for very long. Applying pressure, even very light pressure, along different parts of this strip will cause the touchpad to behave differently.

It certainly seems that there is a hardware and/or engineering problem here, but it is also curious that a reboot will always cause the touchpad to initially work properly until it fails again. I wish I could believe that the problem has been addressed with new hardware, but my experience does not bear that out.

I'm ready to request a complete replacement machine but don't see much point until I know that the new ones don't have the same problem.

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

Several months since my keyboard, palmrest & touchpad were replaced and the problem is well and truely gone.

It's not a subtle change...my machine was unusable via touchpad, and now it's fine.

Sorry to hear that some guys are getting bad parts replaced with bad parts...but keep trying or push for a whole machine swap.

Good parts are out there somewhere!

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

Thank you all for your diligence.  I only found this thread tonight.

I too recently acquired a Dell M6500 pre-installed with Win 7 64-bit and am having this symptom (as well as others).  I contacted Dell support via chat and they helped me find the driver download site.  I updated all the drivers relevant to my system -- only a few were actually out of date (and the Synaptics driver was one of them).

Like others, the fix was only temporary.  

Rebooting only works inconsistently and only temporary ranging between 4 minutes - 30 minutes elapsed time before symptoms show up again.  However, rebooting is a horrible 'fix' for anything not to mention it is completely disruptive -- especially in my case as I work with multiple virtual machines simulataneously.  This laptop was specifically puchased and configured for that purpose with 16GB RAM, Quad-Core i7-920s @ 2.0GHz, SS Disk, and GigE networking.  

Like ckantack, I updated the drivers and the solution worked temporarily, but returned quickly.  

Like JM in VA, I get a deadzone, but only when Win 7 was installed.  It's pretty much starts exactly half way across the touchpad and goes to the left border.  Happily, I haven't seen the dead zone yet with Ubuntu, but it is still frustratingly erratic and jumpy.

Like carheden, I installed a non-Windows OS to try and rule that out.  I chose Ubuntu instead of Debian and Ubuntu 10.04 2.6.32-25-generic is currently installed and same problems exist minus deadzone.  All other devices functioning as expected.

Like dbongard, I tried Windows update, had Jog disabled, not a video card issue that I could tell (although I do have an ATI card, but it's up to date and have no other symptoms at all -- it's gorgeous), and had trouble from the first boot after unboxing and I have now verified this problem exists on multi-OSes (see above).

Like Nato14, I am now finding that heat seems to be involved, though I have not observed this enough.

UNLIKE others, I already had the most up to date version of BIOS (A04) so no flashing necessary there.

UNLIKE reggiewaters, I opted not to install the generic Synaptics drivers as the website indicates the hw manufacturer is responsible for modifying it for their specific hardware.  

To sum up symptoms:

Touchpad jumps left as soon as it is I try to move it right.  It is also erratic and is either hyper-sensitive or at times dead half-way.  It is exactly half way with functionality only working on the right half of the touchpad.  The left half is a dead zone.  It is very annoying.  

The stick device works as do other external mice.

It seems to me the touchpad itself is the issue.  And now with successes like dbongard, it seems reasonable.  It's clearly a larger problem than just a few bad machines.

I am going to call Dell support and reference this thread.

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

I had my palm rest assembly (includes touch pad) replaced and the problem has gone away for almost two weeks now. I just have to figure out how to take the keyboard off and move whatever is causing the raised portion around the sdf area of the keyboard. After it was replaced I installed the just out touch pad driver and it kept stopping cursor movements, buttons and pointer still worked just not touch pad movement, so I put the old driver back in and have not had a problem since.

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

Hi,

I have the same probelm here with a M6500.

(I hope, you can understand my "german english")


Yesterday i got the solution. DELL needed 4 tries to fix this!
The last try was to replace the complete notebook with a new one. 😉
1st try: replace palmrest
2nd try: replace mainboard
3rd try: replace keyboard and palmrest again

my configuration:
i5-520, 4 GB RAM, BIOS A04, Win7 Pro 64 german.

I can reproduce the problem with the touchpad by pressing one of the three keys under the pad. Mostly i need only one time key press to switch the pad to the "fault mode". Some times I need 2 or 3. When I never press one of this keys, it's all right with the pad.

I can switch back from "fault" to "normal mode", when I put the system in power save mode with Fn-F1 and wake up. Or, of course, with reboot.

In my case the OS and driver are not relevant. In the BIOS setup (F2 at boot time) I have the same behavior. I must only press one of these keys and the trouble with the pad goes on. And there is no OS oder driver running.

With Win7 you can track what the pad thinks where the finger is touched. The tool ist the Synyptics-MoodPad. This is allready installed and executable from here (with DELL-Drivers too):
C:\Program Files\Synaptics\SynTP\SynMood.exe


I see with this tool, when I touch left, the pad thinks my finger is half right. Well, checked this out...

bye,
Thomas

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

Purchased a M6500 about one month ago.... wow... this is the first precision that has not preformed for us... we are a design firm and the touch pads are very important for 3D BIM autocad work..... we had the same issues... after replacing motherboard and the ATI graphics card... with no avail.... Dell sent me a new machine... few things I notice... 

1. Then new machine had a much smaller powere pack... like half the size...!!!! thats great given the first one was like a boat anchor.

2. New power supply lights up at the point of the machine instead of at the power pac so you can clearly tell if power is at the machine.

3. Much faster

4. NVIDIA graphics card instead of ATI ... Talked to my I.T. Guy... he said much better!

5. Still having the same issues with the mouse....  intermittently it gets drunk....... only fix.... reboot..... DELL PLEASE GET THIS FIXED ASAP!

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

After calling Dell Support, I was assisted with some additional troubleshooting.  I took out the hard drive and booted to the BIOS to see if I could duplicate the touchpad behavior w/o the OS.  

 

I was not able to.  The touchpad functioned well in the BIOS (presumably without the benefit of any downloaded drivers).  So the problem only seems to occur when there is an OS and/or software involved.  This led the Dell Support tech that perhaps my image was corrupt.

So I asked for a new image.  

The only problem here is that laptop configuration has 4 x 4GB RAM chips and the image recovery CD/DVDs require <= 2GB RAM.  So I was shipped the OEM Win 7 install media and the Drivers DVDs.

I received them yesterday and installed right away.  However, here I am to report the same problem with the touchpad.

Tech support is now scheduling a touchpad replacement.  I will keep all posted.

Re: Precision M6500 touchpad jumps left a few inches when moving finger right

So the Dell technician came today and replaced a few boards, the palm rest, touchpad and buttons.  So far so good!  I will keep you posted.
