HP Stream 11ak0502sa CMOS Battery?

[JSmithy70]

Hi everyone,

I have a HP Stream 11ak0502sa which is presenting a CMOS battery checksum error every time I try to boot it. I press enter and the error just keeps looping.

I believe I need to replace the CMOS battery but I can't see in the user manual that it actually has one? Does this mean the main battery handles this instead?

Many thanks.
