It means you have to replace the cmos battery, which is on the Motherboard. It looks like a large watch battery and you should be able to get one from any computer shop. Take the old one with you to make sure you get the correct type.

There is a battery inside the PC that powers an internal clock and keeps the setup of the BIOS all nice and cosy.

This battery (one of those little circular ones) has probably "gone flat". You need another battery...

However it would appear from what i have seen on my searches this message maybe a fault wth the motherboard. The battery fits onto the motherboard.

I would get a new battery and see it that clears the message.

Before you swap the battery take note of your BIOS settings just in case
