R3000 CMOS Battery: 2009
The CMOS battery in my Compaq R-3000 laptop computer (2004 vintage) is dead This means that the system forgets the BIOS configuration settings each time you turn it off. So, I am eager to replace this battery. I’ll track this effort in the comments below.
Please note that this is not the same computer as the Compaq 3000 laptop, that I describe here, and whose battery also went dead. Both the 3000 and the R-3000 computers require new CMOS batteries.

03:50 PM: I found instructions here for taking the Presario R3000 apart. These should prove most useful for this project.
03:55 PM: Other posters indicate that the CMOS battery on this notebook is soldered to the motherboard and located beneath the keyboard. I’ll confirm this once I verify it for myself.
