my brother has a HP 635 and fan doesnt work and when try to start give me error "fan not operating correctly).
so i look on google what's the problem and try to clean and still nothing, than try to blow in fan and nothing.
Than order a new fan here on HP and put notebook together, there is no error message, but fan doesn't spinn, again i try to blow in, still nothing. I read also that this could be problem with bios, and i update bios. and fan doesn't work.
than i take old fan and try connect to 5 volts and it spinns normally.
So with the fan is nothing wrong, what could be ?
