fan error 90b on start up

hp 15-ac130ds
Microsoft Windows 10 (64-bit)

my laptop has the fan error 90b on start up, and if you hit the enter key to acknowledge it, the laptop works fine.

My laptop is a  hp 15-ac130ds, and it does not have a fan on the main board, just a heatsink.

I have updated the BIOS to the latest version of F.29, the OS has  been freshly installed with all updates, TPM cleared, and a hard reset on the laptop.

Any suggestions to get rid of the fan 90b message?
