Sony vaio e series cmos location

SOURCE: Cmos battery

You must enter the laptop internally that is.  In some laptops it is soldered to the motherboard be prepared to find that.  Did you know it takes a long time for the battery to be stuffed because.  Are you certain that the problem is the battery?.  If it is stuffed your bios would have resetted itself to the default settings and will not hold your settings.

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

It should be located somewhere on the motherboard wich means pulling the computer completely apart which unless you know what you are doing may be a little difficult for some, but not inpossible.
