I have an older Compaq Presario laptop.  It is a 1200 series model 12XL325, specifically.  

I need to replace the CMOS battery (based on the fact that the date keeps getting reset to 1/1/1999).  I would like to avoid taking the entire laptop apart looking for the needle in the haystack, so guidance here would be very helpful.

Here's an internal pic of the 1200: http://www.rainwulf.com/articles/article_laptop.html

Behind the white socket there appears to be a CMOS battery.
