Trying to find CMOS battery in a Compaq Presario C500
This thread is old but thought I'd would share this. You don't have to take the whole computer apart... Just take the Memory Cover off theres a chip there with 2 wires coming from it just remove the 2 little screws and the cmos battery is located underneath that... Just an FYI... Jp
A good FYI
Anyway, yeah, just remove the wireless card after removing the memory cover. Additional bit of info: It's a standard C2032/CR2032 watch battery, same as most desktop boards.
Gone (for the most part) are the days of proprietary CMOS battery connections, thank god.

Hi there, I was looking for the location of this CMOS battery in the Compaq Presario C500 but this information was hard to get. Unbelivable!!, but thanks to you response I was able to replaced it. I just removed those 2 small screws from the memory cover, the Wi-FI card was next to the memory chips, I removed the WI-FI card (there are 2 small screws retaining the card), put it aside with the 2 wires still connected, and the CMOS battery was there. I removed it carefully and replaced with the new one, put the Wi-Fi card back and put back the screws, closed the memory cover and all done!
