Hi, im getting trouble with that last step as well, I get the device manager, mice and other, synaptics Ps/2,properties.. but when the properties window opens I have no advanced settings to change so from time to time I keep getting the reversed touchpad.. any help??

ive given up on legitimately fixing this problem, but what ive been doing recently is after i log into my user name, i click and hold the mouse button (so it will make the rectangular selection box on the desktop) and i keep moving it in a counter clockwise motion while the applications load. when the touchpad icon in the taskbar shows up the mouse freezes for a second and it should calibrate itself the right way. this has worked for me everytime for the past week. i do it when i take it out of standby also- just click the left mouse button and start moving on the touchpad then press a button to take it out of standby hope this works for yall...

Well I don't want to raise false hopes but my VGN-sz3xwp/c touch pad is now working perfectly. Not sure exactly why but these were the steps I took (1) installed alps driver v5.5.1302.12. .....See article on http://forum.notebookreview.com/showthread.php?t=138509
This solved most of the problems but I had one or two lock ups where the pointer would fail to respond to the touch pad. I then downloaded XP service pack 3 and since then no further problems. I will monitor and come back with an update in a month or so.

Like many suspect, the problem is hardware related, not software.
It is due to the aluminum palm-rest surrounding the touch-pad. I'm not sure if it is a short circuit or a bad ground. But all you need to repair this problem is a little electrical tape. Check out this site for details (and pics) on how to use the tape to insulate the touch-pad:

Also you may need help dismantelling the laptop go to this site:

another temporary solution.... download the synaptics driver, cancel the automatic wireless conection and stop using the fingerprint sensor on startup.. if you dont want to dismantle your computer.. this will work fine, has worked for me for about 3 weeks now without any problems.. good luck

Hi all,

I am glad that I found this forum. I have the same problem with mouse pointer inverted with sony sz640 laptop. I found the fixed solution, at least for me. I think I should share this with you all who are still having this problem.

The problem occured after I installed a usb mouse driver which did not support Windows Vista. I am running Windows Vista Business. After reading one of the post from this forum, I figured out that my poiting device driver might have corrupted by my usb mouse driver installation. I also read in one post that the wireless might have something to do with it. I agreed with that suggestion, I noticed that after the reboot, if the wi-fi software starts ok, then I have mouse inverted problem, if the wi-fi software could not starts then I the mouse is ok. But this is just a temporary fix. I want a permernant fix.

I decided to reinstall the poiting device driver back to the original from sony. To be safe, I dowload the driver from sony 's support web site follows by the operating system. I reinstalled the driver, and it works like a charm. The problem with mouse pointer inverted is permanent fixed for me.

Hope this helps.

Cutie.

I spent weeks trying various solutions found on this and other boards. Some worked temporarily, most didn't. Most appeal to a human quality that we think what we did causes change when in reality sometimes the problem is there and sometimes it is not and replacing drivers with dell etc, switching wireless button off during boot or attempting a freemason handshake with an inanimate object has no effect at all.

I finally bit the bullet and called Sony, armed with all these stories about how many people were suffering with the reversed touchpad problem, determined to take no prisoners.

I was disappointed, they didn't even put up a fight, despite my SZ6 being just out of warranty. They acknowledged it was a hardware issue, picked the laptop up, and delivered it a few days later with new touchpad. Problem solved.

Service couldn't have been better, I just want to thank everyone that has raised and fought this issue in the past, as it appears Sony have listened and responded.

If your laptop is well out of warranty and they won't touch it, get a new touchpad and fit it yourself if you feel brave, google VGNsz.pdf for disasembley instructions, or try the fix above using insulting tape rather than a new touchpad.

I have had the problem recently intermitently on an SZ bought 3 months ago went through a lot of info which often conflicts all the while with a reversed touchpad (which btw I find when it does reverse the best way is to use the left hand and with a bit of practice you can use it)
ANYWAY I found one post sugesting to close the lid and re-open which I did and it reverted immediately,now I have only just come across this solution and only had to do it once but it sure beats any of the other solutions and must be the first thing to try.
Good Luck!

Go to this web site.

http://www.synaptics.com/support/drive.cfm

Look at your OS.

Download driver.

Disable the biometric fingerprint reader.

Go into control panel -> Mouse "It is under one of the icons after you click them" . Not in system.

Go to pointing driver. Roll back or choose driver that you extracted.

Good Luck.

Stop trying to update your touchpad driver. The solution is temporary at best its a hardware issue. You have two choices, contact sony and hope they will replace your touchpad. Or follow the instructions above on how to insulate the touchpad from the palmrest yourself.

thanks ivangill- i have been suffering for a while and also finally called Sony after reading your post. My warrently is also just out of date (as of 9/20/08) but they didn't protest. the tech person originally tried to lead me through a software who-knows-what fix, but I stopped him, let him know I was aware the issue was a hardware (not a software) issue caused by the aluminum palm-rest. I also let him know I was aware this was a common problem with my model (SZ650N). With not much more delay he said he was sending a box to my house that would allow me to ship my laptop for repair for San Diego. He said they would replace my mouse. SO...we will see. Good luck to others.

Please try downloading the software from this website before changing the hardware.

I need a extra person to confirm this fix.
This must be something to do with the corruption of the drivers. Because if the hardware is broken, it will not respond. It knows whats left to right and up down but reversed.

If you plug a usb mouse into the laptop. The touchpad will work like it should. If you unplug it, it will not work and be reversed. I find it to be software related because of this test.

Hi, I downloaded the driver a few months ago.. the touchpad has worked fine since then. hasnt reversed once, doesnt matter if the wireless button is on or off.

Changing the driver is a much easier fix than dealing with sony´s customer support.

agfraser76

I also downloaded the driver and all seems to be working ok now. will keep you posted if anything changes.

I downloaded the Synaptics driver last week, just to see. Worked for a week and now it is reversing again. But maybe something different is wrong with my laptop- the internal mouse reverses even when I have an external mouse plugged into the USB. Plus, it used to revert to normal when I closed and re-opened the top of my laptop, but even that fix doesn't seem to work anymore.

ajhoff

Lizzygal,
You seemed to have the same problem as me. The Synaptics driver was only a temporary solution (as long as the entering sleep mode, or disabling the fingerprint driver, or disabling wireless switch) because these are software 'fixes'.
You should either try to contact sony and have them replace your touchpad. (I have been told they will replace the touchpad even if your warranty is expired, because so many people have had this problem.) Or if you want a quicker fix, try the tape method I mentioned above.

To other people backing the synaptics driver method. I'm glad its working for you, hope you don't have any more problems.
But just think about it, your using a Synaptics driver for an ALPS touchpad, its probably not the best or even a permanant fix. And this issue has been proven to be a hardware issue by many people. you should search for a hardware fix.

Hi all,

I have a Sony VGN-SZ381P laptop and have been pulling my hair trying to fix the touchpad just like everyone else here. Unfortunately, in my case none of the mentioned problems worked. I've tried about any fix out there but nothing worked so far. Anyway, to make a long story short, I've finally found my solution. What has fixed the problem is in fact a much more recent driver from Alps. Since Sony has abandoned any updates for my computer there wasn't much choice but to try other OEM drivers. In this case the driver was a Toshiba Alps Touchpad Driver 7.0.301.4 and it's a Vista driver. My above mentioned laptop is running XP Pro SP2 with the current patches. Below is a link where I found the driver but if it doesn't work you can google it.

Please also note that I've installed this over the original Sony Alps driver found on their website (version 5.3.512.4) and tweak that suggests to disable mouse wheel and fast initialization has NOT been applied. So the scrolling and all that is working fine still.

Good luck, hope it helps.

I have the same problem with my SZ740N4. After reading this thread and trying out some of the tips, I would like to suggest trying the latest version 7.2.303.101 from Alps meant for Toshiba touchpads. Very stable through. No more reverse since. Google for it. I cannot remember the link

Around one in every 10 times after starting a client's Sony Vaio SZ touchpad was "reversed".

Having read through the posts we booted the laptop in DOS and then ran a mouse based application and it to showed the same issue.

So the problem is a hardware issue - not anything to do with Windows, time to talk to Sony Support (and yep, just out of Warranty).
