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.

For that open back cover of laptop.
Then find motherbord .
Pull cmos cell from motherbord for 10 minutes then refix.
Also pull RAM memory then reconnect.
Then if problem remains then you have to change battery .
Let me know if you need more assistance.
Thanks.

You may need to take the computer after and remove all connection from the MOBO, processor and ram and then put them back and power on the computer and check if that correct the problem......

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

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.

Probably a memory problem even though it doesn't show up on a memory test. Enter the bios and select the option for default setup, "not the optimized setup". Also if you have more then one memory module, remove one and try the install, if you have two try using the one you removed first as the only memory module during the install process. If you have any cards plugged into the computer, remove them all before starting the install. Also all usb cables. Make the system as simple as you can for the new install.

Blue thin lines before it boots will rule out an operating system or driver fault. So it would appear something in the machine has failed.
Do you have a VGA monitor you can connect to it and see whether it shows the fault? This will show that if the fault also shows on the external monitor, it is likely an electronic fault on the main board, whereas if it works on the external monitor but not on the built-in monitor, my guess would be the cable that goes from the main board up through the hinge of the screen into it, or a connector, or an actual fault with the LCD display.
Windows booting normally once the display drivers were disabled indicates to me that Windows is no longer detecting the faulty display and therefore boots normally - possibly pointing to failed electronics in some way. It could even be corrupt BIOS that controls the video or something along these lines, though that's unlikely.
Good luck, either way it sounds like it's off to a computer repair shop. Is it under warranty?

to restart in BIOS in sony vaio press F2 or F3

try Fn and F5/F6/F7

Good afternoon, smarx and welcome!

You might want to check the lid switch to verify that it is working correctly. These things do go bad or can become sticky.

Hope this is of some help, and have a good day.

There are panel/covers on the base or near the bottom edge of most laptops these enclose the RAM and hard drive. Remove these screws and covers to reveal the hard drive and possibly the hard drive carrier.
Before you attempt this I suggest to login to the Sony WEB site and download the drivers for the graphics and sound device including modem and LAN if you don't already have them and back up your data. You will need these drivers when you install a new and larger hard disk and the operating system.

Hi,

I've owned three SONY Vaios and every one was bad trouble for me, though I kind of admired them anyway. Here's some tips.

The docking problem is a common one. If you are "undocking" the Vaio using the software command UNDOCK, and it still crashes, you have a software driver problem; you need to uninstall the SONY power and docking drivers, reboot, and re-install them.

The sluggish performance is another common problem, generally caused by the scores of little programs SONY installs to tweak their custom hardware, and sell other company's products on your laptop. The only solution I ever found to this is to uninstall all of the extra SONY software, or, better still, reinstall the operating system and only install the SONY drivers and software that are necessary for core system functionality.

Problems with photos loading could be anything, but might well be interference with SONY's own photo software. Try uninstalling it.

Problems in Outlook; try going into the options section and removing and re-installing the dictionary. Or use the free Thunderbird mail client from Mozilla, since Outlook is buggy, insecure, and annoying.

Good luck...

Hi dheerendra let me know the display massage when you are start your system by pressing the power key. let me know are you able to boot the system or not. Try to put windows xp bootable cd in drive and choose boot from cdro option in cmos setup. when setup is started then choose repair option.

it's possibly a hardware problem but you should make sure it isn't a software problem by putting in your system restore cd and restoring the DLL that you deleted, it could be an important system file. If it is a hardware problem, the first thing to try is taking out your memory and sticking it back in place, make sure it's clean and put it in there tight.

Unplug the power adapter and take the battery out. After a minute, plug them back in and push the power button.

If you only erased it, you can simply use the keyboard shortcut CTRL+Z, if the deletion was permanent, there is nothing you can do.
