I have an HP 15-db0010nr laptop with no cooling fan - it only came with a heat dissipation plate. I get a 90B fan error every time I turn on the laptop. I have done a hard reset, downloaded an updated bios and done a bios reset, I have replaced the thermal compound on the cpu. There is a place the fan would fit but no power port on the motherboard available for it. I'm at a loss what to do. Thank you.
