i am having the same problem with my dv7. Error cooling 902 error appears and i have even tried blowing air into the vents to no vail. Although there is HP service station nearby my house so i went there to see if they can fix it up. Here i want to mention that i am from Pakistan so there are not many certified engineers available. Well anyway we tried to reach bios screen but it is almost impossible to bypass the 902 error screen. The fan is also working but it is slow and when you put you ear to listen to it closely it gives a racing up sound and slows again. its like its speed its slower and variable not constant. Furthermore one of the engineer told me that IT could be problem with the fan cable or maybe with the board that is causing this issue because even if fan has slower speed the error message should not pop up. Although they have asked me to take my harddrives and give them the laptop so that they can figureout something for it. They told me that they will contact some one in singapore HP center in order to take a hint whats going on. Important point to note is that if all of the blowing compressed air and failed attempts to reach bios screen is present and still 902 error message comes up than there could be a problem with the circuit of the fan i.e. it could have damaged overtime due to overheating and thus needs a change. I will keep u all updated what will happen next as they have asked for a week to repair the problem.

I have the same problem. Blowing does not do it.
I pulled battery and "drained". that worked once. Fan was working fine.
Happened again. Now won't start.
It happens when it goes to sleep and I try to bring it back up.
I updated BIOS when I had it working. Stopped next day again.
I feel its a software/ design error of some sort.
I then had FAN replaced. Old fan was fine. Worked for a while.
Happened again... I think after it went to sleep. HP runs great when its working.
Any ideas? Nothing but mumbo Jumbo talking to support and a waste of time.

it is should be the fan stuck by dust so you can fix by by blowing into it.
I have a G62 model and had the same problem.I cleaned the fan but no effect,then I updated the bios and it fixed.
There are two aspects to think about the preblem,hardware and software. blowing into it (cleaning the fan or exchange a new fan) may solve the hardware problem and updating the bios is solve the software problem.

I have a HP G62-b26SA Notebook and I keep getting this error message when I turn my laptop on. I can't seem to find the BIOS online for this product and I've tried blowing into the vents!
Can anyone help?!
