Laptop not holding charge

My friend has a hp laptop where it was not holding charge. He bought a replacement battery few months ago and it charged fine. He's saying now that it's not charging and he has a CMOS error message.

Any ideas what the problem is?

You'll need to post more info. What is the CMOS error exactly?

The CMOS checksum is incorrect. It will be reset to default configuration.

CMOS reset (502)

I believe it was £30.

So the CMOS is wrapped in some kind of flexible plastic not like the others where you can pop it out.

Does he need to buy one where it's also wrapped like that?
