How to replace a VGN-FS680 keyboard I'm trying

every laptop is different some have screws underneath some have a part of the casing above the keyboard that can be removed by sliding it to one side revealing the screws underneath this could also house the power buttons and some unfortunately require the complete laptop motherboard etc removing first and i know with my sony this is what i had to do, so firstly check for a strip above the keyboard and try sliding it to one side, if there is a strip then youre in luck as it will normally reveal 3 screws holding down the keyboard which will allow the keyboard to lift and unclip and then you just need to unclip the ribbon cable from the motherboard, if theres no strip then you could try turning the laptop over and removing any screws that are directly under the keyboard and see if this frees it and also removing any memory and hard drive that may be hiding any screws, if this does not solve your problem then you are heading for a complete stripdown of the laptop base which unless you feel competent in doing so is best left to the experts, hope this helps

Hello sir, hi, most laptop and desktop computers BIOS is powered by a cmos battery, removing this battery and power on the unit will clear the cmos momentarily. including no password. BUT removing the battery needs dissassembly of the laptop. Some laptops the battery is under the keyboard, if this is not your options try google and search removal bios password.

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.

try using an external keyboard, reboot the computer then pre f10 key repeatedly for 5-7secs to boot to vaio recovery center.. select restore c: drive to format the harddrive to the factory defaults

Here is the link to your service manual, the keyboard removal procedure starts on page 7. It is in full color pictures and detailed.

You need to remove, or short, the cmos battery. I'll be on the motherboard somewhere, possibly under the keyboard. Remove all screws, carefully, slide back any tabs on the keyboard and carefully remove. Only do this if your warranty has expired.

The one I used to have has a strip along the keyboard in between the LCD hinges & the keyboard. Pry it up from one side & it will reveal the base screws. I used to have the web page printed out that shows the entire breakdown, but I can't find it anymore.
Mine was overheating, cleaned all the dust out ... And it was FULL!

Correction...

The CMOS battery is located under the system board, and is not accessible from under the keyboard.

The keyboard has to be removed in order to change the CMOS batter, (another reason why I don't like Sony laptops.)

Below is the batter I just pulled from a user's VGN-FS660\W
