How to open case on VAIO VGN-TX670P

Problem with a Sony Vaio. It seems one of the updates put entries in my registry to start a Vaio Lan Manager with Windows.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

Check these keys to see if any kind of a 3rd party Lan Manager is running. If so, delete the entries and reboot.

To reset the BIOS password read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD.

If I recall correctly, there are eight screws (maybe nine?) that need to be removed from the bottom of the machine, then the keyboard gets pushed down toward the front of the computer just enough to clear four tabs at the top. Then lift up, push toward the screen to clear four tabs at the bottom. Turn the keyboard upside-down to reveal the cable underneath. Flip up the latch and remove the cable from the system board.

You must get the Driver & install for that model I think that is what you need below... really you should download ALL these drivers and store them on a DVD for later use...

with the laptop over on its back you will see two screw holes seperated apart by a couple inches right in the middle of the case. These screw holes are in the middle of two recesses molded into the case bottom. The screw on the right is the screw that releases the keyboard. Once this screw is removed, the only other thing holding the laptop keyboard is the 5 retaining tabs along the bottom of the keyboard. Release these and rotate the keyboard up and release the cable from the motherboard.

Sony makes getting a keyboard off it laptop like trying to launch a shuttle craft. Take the three screws out on the bottom, Push in the two detent tabs at the top of the keyboard, the hold it in place when on the palmrest. They are located at F5 and Num Lock keys. Now take a thin skewer or wire and push through where the screws were, this will release the keyboard. Now slide the keyboard toward the screen and that releases the lower detents that hold it at the lower part of the palmrest....nor unplug the cable and you are good to go. Oh, by the way below is the link to the service manual for your laptop....it has it fully illustrated.....

try to download the manual from http:www.sonyvio.com

you have to detach the keyboard

you'll find that there are usually 2 to 3 smaller screws, which hold that top down. Look right above keyboard, for small, sometimes, color or arrow identified screws. that should get you there.
