See the service teardown video at the link below:

 

Removing & replacing parts for HP Slim 290-p0000 | HP Computer Service

 

The actual CMOS battery removal is under the 'Restore CMOS to Factory Settings' section but further disassembly is required before you can access the battery, so watch those applicable sections as well.
