I recently installed a new HDD (Seagate ST9500424AS; p/n 9RW143-567) in my Sony VAIO VPCEH11FX and installed Windows 7 OS using the Sony VAIO Recovery Media Kit (VPCE_10FX Series 989203008). During the installation, I selected the default or normal settings.
A short while (1-2 weeks) after the installation was complete, I noticed that the track pad was not working after enabling it using Fn+F1. (The pointing device dialog box DOES appear when I press Fn+F1 and shows that it will toggle between enable & disable). I took the computer into Fry's (where I bought it) and they booted a different OS (I think it was Windows XP) using a CD. Using this OS, the track pad worked. So it was confirmed it wasn't a hardware issue.
I proceeded to contact Sony. They had me do the following:
1) download the latest drivers & driver updates and install both. This didn't fix the problem.
2) uninstall 'Alps Pointing-device for VAIO' and run the .exe files for the driver & update. This didn't fix the problem.
3) boot the computer to recovery mode (press F10 when it starts); I noticed that the track pad was working in this mode.
4) Confirm that the other ALT keys functioned properly. (they do function properly)
The Sony rep asked me to confirm the type of HDD I installed (I forget what specifically he was interested in), but upon my reading him the part number, he confirmed the HDD was compatible.
The Sony rep then suggested I either recover the system to a previous version/date and see if the track pad is working. (he seems to think some software I installed might have prevented the track pad from working) He also suggested I could reformat the HDD and reinstall the entire OS. I've balked at doing either, as I'm guessing there is an issue with the registry.
Does anyone know what the issue might be?
Thanks in advance for your help.

My suggestion is to go to Device Manager and under Mice and other pointing Devices choose the corresponding mouse and check that it is not disabled, then uninstall it and click on Scan for Hardware changes then let Windows 7 do its thing which will be to install a generic driver that should let you use your trackpad, then if all is working install the Sony driver, or not its your choice.
If that doesn't work I would re-install the OS. But that's just me, I have become very efficient when doing backups and installing an OS and can have my system up and running in less than 2 hours with everything installed to the way it was.
Everything I write is Sarcasm.
I've tried the uninstall & reinstall of the driver and it doesn't work.
Why would wiping the drive clean and reinstalling the OS fix the problem if when I last installed the OS, the track pad didn't work?
If I'm correctly following the timeline you reported, the time you noticed the trackpad wasn't working right was quite some time after your 'last installed the OS' install. During that interval, all sorts of variables could have been introduced by software (including seemingly unrelated software), updates, registry changes, setting changes, etc and any of them could introduce a driver, registry, conflict, etc. issue that might be mitigated by trying a truly 'clean' install. It wasn't really a 'clean' install.
Also, make sure the hardware and software configuration is as simple as possible if you re-format and re-install the OS (e.g. don't have any non-critical devices or device settings installed, or connected, or enabled in BIOS/UEFI) while you are trying to debug a problem. As one example of such, have ALL power management disabled both in BIOS/UEFI and in any options that are presented as you install the OS. Disable all sleep/hibernate modes, etc. Make sure BIOS/UEFI options are disabled (as appropriate) before starting the new OS install.
I have recently bought a brand new Sony Vaio VPCEH35EN series laptop. The touchpad of the system suddenly stopped working and I have used all possible steps without voiding the warranty norms to restore the system but it seldom respond to any. The funny thing that when I check its driver (Alps) details in device manager everything shows normal and correct. What could be the problem, even if that is repaired under warranty will such problem persist. Please advice suitable solution and some details on such issue occurs.
