Re: System Fan (90B) Error

Either the CPU fan is clogged with dust or has failed, clean or replace the fan.

 

See this guide for cleaning instructions

Re: System Fan (90B) Error

Can I ask for instructions for disassemble the notebook and how to clean the CPU fan?

Re: System Fan (90B) Error

You don't need to disassemble to clean the fan, the link I posted earlier showed how using canned air.

 

Your Service Manual can be found on this page

Re: System Fan (90B) Error

Is the notebook under warranty? If it is HP will repair it for free.

Contact HP directly, they will guide you on what to do next to get it repaired under warranty


USA

Everywhere else

If you have no warranty:

 

Best thing to do is call HP parts

 

 call (800) 227-8164 between 5 AM and 5 PM Pacific Time, Monday thru Friday.

 

they will ask for serial numbers from the PC, this way they can get you the correct part number.

 

It requires some skill to replace the fan, its not for the inexperienced. I suggest taking it to a qualified reputable repair shop to install it.
