I have an older system ( XPS 435T / 9000 ) in which the CMOS battery was replaced. I want to verify that the correct battery was used. I checked the online PDF manuals, but they don't list the specific battery model/part number for the CMOS battery. Is that information listed anywhere?
Why? If the computer boots up, the right battery was used-- a CR 2032 coin cell battery that can be bought in any store for less than $2.
See pg 59 of the service manual.-- https://downloads.dell.com/Manuals/all-products/esuprt_desktop/esuprt_studio_xps_desktop/studio-xps-...
