Sony VAIO VGN-SZ460N/C Notebook - Answered Questions & Fixed issues

install website sony vaio and fn keys function software install

My Vaio touchpad started behaving strange. I could move the curser, but no response on left or right click or double tap. Also found that in any search field or user name fields, the computer would just type endless 9's. My wireless mouse could operate the left and right click buttons, but not move the curser. A suggestion to get the mousepad operating again was to touch any key on the keyboard. This allowed it to function again. Final solution was to remove the battery, then hold down the start key for about a minute, reinsert the battery and start it up. It seems to have resolved the problem. I have a 3 month only laptop with Windows 7 already installed. Hope this helps.

To resolve these problems, you can simply change or reset forgotten Windows password with a Windows password reset disk. A password reset disk is a flash drive configured with your current password, specially formatted to reset the password on Windows machine when you ever forget it. It acts as a key to unlock the account. But the problem is that we often forgot to create a password reset disk and cannot log on computer with any user account.Of course, a common solution is to use a third party software, just take Windows Password Unlocker for example. It can help you remove lost Windows password including Windows administrator, user and domain password on Windows 7/Vista/XP/2000/2003(R2)/2008(R2), etc. You can easily reset Windows password with a bootable CD/DVD or USB flash drive in hand.

I THINK YOU HAVE NOT INSTALLED THE DISPLAY DRIVERS. SO PLS INSTALL ALL THE DRIVERS AND THEN EVERYTHING SHOULG WORK FINE.

Hello,

Try to go to the manufacturer's website. Manufacturer's usually provide device drivers for download.

Here is the link for the Bluetooth driver for your device : Original Drivers and Applications for VPCYB Series : Bluetooth Driver.

Note that this is the direct download. As soon as you click on it, the download will begin.

Hope this resolves the problem.

The first step should be to browse the producers website to see if there are drivers for Windows 7. If not you can try to install vista drivers for your peripherals many times they work anyway.

Your Notebook Manufacturing Company SONY says that your Notebook Model VGN-SZ460N/C is optimized to work with Vista OS only. So the drivers you will be installing for XP may lost some of their functionality under XP platform. Still, you can download all your Notebook supporting drivers from this link.

Download Drivers from here


But remember to select your Operating System (XP/Vista/Seven) when you will be downloading from the above site.

I hope this will be helpful to you.

uninstall all the device drivers and start installing individual drivers one by one.

you will see what driver is cause this problem so to avoid this problem

thank you

The camera driver/software might got corrupted or conflicts with other/ third party applications.
What you can do is to try reinstalling the camera drivers and software from the link below

http://esupport.sony.com/US/perl/swu-list.pl?mdl=VGNSZ460NC

the camera drivers/software are listed under
Camera - 4 file(s)

Be sure to install everything under that category. Start from bottom to top.

your laptop is warantee time so inform company service center.

It sounds like you might have a fan problem that overloaded your HDD, if this is the case you might need to get a whole new HDD because the information can be fried. If possible, backup your information and install it on the new HDD if that's the case.

Generally, if a mouse button quits working, it requires the replacement of the touchpad assembly.
Boot to the safe mode, see if the button works there, if it doesn't, then it is a failure of the switch in the button

Possibly you have a programme running in the background that is causing the freezes, could be a screensaver. i think at sometime microsoft will issue an update that will fix this problem.

Here is the link to the factory service manual for disassembly.....

remove the battery then insert again,..

Hi,
Better to install MS Office 2007 or Office XP.
Note:Before Installing new office software,please remove old one.

your hard drive has failed as far as i can tell you will need to replace it take it to a sony store for verification

I put my money on that you have a CPU over temperature problem, and/or intermittent RAM problem.

Be sure you are ESD safe when working on the electronics as follow !

I suggest, using a eye piece magnifier and a wooden tooth pick and carefully touch each pin of your RAM sockets and see if the soldering is bad, allowing the pin to move slightly. If that happens, well it needs re-soldering there, make sure you use leaded solder, not the ROHS crapp.

If that turns out to be ok, then check your processor. It might over heat.
You may want to observe if the CPU fans runs at all and if it runs at full speed most the time, even if you don't run any 'heavy' programs. This usually would indicate poor heat dissipation. Most Sony Laptops have a piece of thermal foam pad is used for heat transfer from the CPU chip into the heat sink. Over time this pad shrinks, effectively impeding the heat transfer causing the CPU to over heat and intermittent shutdowns ect. I suggest, find a new piece of thermal pad or replace that with a piece of copper sheet material and use Thermalloy transfer paste.
