My MSO5204 scope stops booting at the BIOS screen and waits for the user to press F1. I suspect the battery that backs up the BIOS is dead.
Can you tell me the battery type and how to access it?

The battery should be on the COM-E Carrier board. The battery should be a CR2032/HF1N. (with solder tabs)
See the service manual at the link below for instrument modules and disassembly.

And of course you can send the MSO5204 into our factory service department and they can do the work.
