It is actually possible for a motherboard to refuse booting up just because a dead CMOS battery is still present?

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Only with something on the pads of the old barrel battery connected they booted.

They still refused to boot even after removing faulty batteries?

I also came across boards that won't boot or even show any signs of life unless a working cmos battery is present.

My K6 system is even weirder since it seems to work with a dead battery but on closer inspection it will never boot any OS and the bios only loads half functional. A new battery fixed it.

So yes, for quite a few boards a working cmos battery is not optional.

I am wondering how many old motherboards and computers got trashed simply because of a dead battery. probably a lot, which is a shame.

That is correct. Only with a working and charged power source on the battery pads/connection they worked.

Any experience with motherboards starting to work after faulty battery was removed?
