Notebook Boot and Lockup

I have never posted before, but I wanted to tell my story in hopes that it helps someone else.  My 3 month old Pavillion dv7-3188cl would not boot, giving me a 902 fan cooling error.  I could not access the BIOS or get into Windows 7, only being given the option to shutdown.

I called HP support and spoke with someone (in India I presume), who walked me through some steps to try to fix it, to no avail.  She said my only option was to ship it to them.  I would have to back up my data before shipping as they would wipe my drives.  They charge about $50 for this and I could not back up myself for obvious reasons.

Unhappy with this option, I tried online chat support, with the same result.  They had me try to get to the BIOS and disconnect my hard drives, but no change at all.

I went to a local computer technician and paid him to back up my drives so I could ship the laptop off to HP for 2 weeks to be repaired.  In doing one last google search for a solution, I found one that suggested blowing into the vents on the bottom of the computer.  I had nothing to lose, so I tried it.  Low and behold, the computer is fixed!

After hours of frustration and paying someone for help, the laptop was fixed by blowing into it.  I did flash the BIOS once it was working again as this was a known issue that could only be fixed once I could boot again.  I hope I can help just one person avoid the nightmare of dealing with HP support.  They throw pleasantries at you constantly tell me that I am their friend and they love me and how great my company is to them, then they are unable to help.
