    I have a Compaq Presario, Series 2900C Laptop, that has a checksum error and won’t hold bios settings, I have spent hours searching the net for information on how to get at cmos battery, I have removed the speaker cover and keyboard and can’t see how to get to the cmos battery I have checked the HP/Compaq site ….no luck. The only info I have found was that Arima Computer Corp partnered with Compaq to manufacture the note book. I am concerned about splitting the case as it is pretty secure, I have removed the 4 screws from the bottom of the laptop case.... Here I sit

    If you could please direct me to this information I will be greatly appreciative

    This is a really old Pentium-based laptop, right? I had one like this, I think it was a 3100 or some such thing. If it's like mine, there should be a small rectanguar plastic piece on the underside of the laptop that you can remove. Under it you'll find the CMOS battery, which looks like a AA battery wrapped in platic with wires sticking out the end. If it isn't there, see if you can get to under the touchpad or trackpoint buttons, laptop manufacturers often like to stick them there. And DON'T expect to find a normal desktop-style battery, laptops often have larger batteries (so they don't need to be replaced as often, and also because laptops are designed not to have power 24/7), usually wrapped in plastic and connected to the motherboard with a pair of wires.
