Mark -- A followup to my previous post. I found the manual for your computer here. As indicated on page 108, the cmos battery (referred to as the RTC battery, because it saves the real-time clock settings as well as the bios configuration settings) is rechargeable on that computer; and it will hold the settings for only about a month when the computer is turned off; and it only recharges when the computer is turned on. That is all unusual in my experience.
Also, apparently on your computer the bios settings are viewed and changed via a software utility that is installed into Windows, rather than by the usual procedure of entering bios setup prior to boot. See page 200 and 201 of the manual.
Hope that helps,
