ON START MY PAVILION dv7 gives no cooling fan error.  if i let it start the keyboard will start to get warm on both upper and lower on the top on the left end. i shut it off before it starts to get hot.  This just started a few day ago.  It tells me updating the BIOS may help, BUT I DON'T KNOW HOW.

A failing fan is a hardware issue and updating the BIOS will not only not fix that, it risks trashing the PC in the process.

With a laptop, if you don't hear the fan, I suspect that it actually is NOT running -- and that is a serious issue as your PC will overheat almost immediately and shut down as a result.

That being the case, you need to get the fan replaced and such repairs can be very difficult and risky to perform, depending on how much stuff has to be removed in order to get to the fan to replace it.

For such repair estimates, you would need to contact an HP Repair or Service Center.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
