I restarted my laptop after applying a Java update this morning. Upon reboot, the first thing to appear is an error message, 90B, which informed me that:
"The operating system has found that a cooling fan has stopped working or is malfunction."
Or a statement very close to that. A week ago I noticed that my laptop fan had been more noisy than usual. And this morning I didn't hear it at all and thought that whatever was causing the noise went away (dust, ect)... Until I restarted my computer. I blew compressed air into the vents of my laptop where my fan and heatsink are located. It was all in vain.
I have also been monitoring my GPU temperature. Up until today it idles around 40C and when charging idles around 55-60C. However, today it has been idling around 60C and when I plug it in it rises to 90C and keeps climbing to 100C. I shut off my laptop because I don't want any damage to occur.
I have also updated my BIOS.
I fear that my fan is broken and may need to be replaced, is there anything I can do to remedy this situation before I have to send in my laptop for repair? The last thing I want to do it mail it in, pay for a fix, and have it break a month later.

|Fan||Fan not operating correctly||90B||The system fan may be malfunctioning.|
For information on troubleshooting heat-related issues, see Fan Runs Constantly, the PC Operates Slower than Expected and Generates Heat .
It is also recommended that you perform a hard reset as that can sometimes restore the system fan to working order. See Use Hard Reset to Resolve Hardware and Software Issues for details.
If the system fan continues to malfunction, contact HP support.

As it looks like the cooling fan has failed, the safest thing to do is not to use your notebook until it has been repaired - you don't want to cause further and potentially much more expensive problems due to overheating.

HP really makes crappy product. I called support, they asked to sign up for 1 year support to $99 to continue the
crappy service. I refused, might as well trash the notebook and switch to another vendor.
Oh, I might short some HPQ stocks to recoupe my loss on the laptop.

DOn't take easy problems hard. THe fan has broke due to debris or some problems. For cooling, temporarily put some thermal paste, but very little, even small than a pea, and spread it. If your boy is wide and heavy, you might put on a fan, thin. iT can be doen easily, get a set of jeweler's screw driver sets.
Hope it helps!
