DV7-2174CA ->should fan be running as soon as laptop is switched on?

[sparrow_69]

I'm troubleshooting a Dv7 (Q9000, amd 4650) notebook. Should the laptop fan be running at all when the notebook if first switched on? Notebook sits at the diagnostics screen for about 20s then shuts down. I'd love to hear from some Dv7 owners on this one. Thanks

It should run as soon as the system power on. Most laptops do this As far as I know. It will then slow down as everything is initialized.

I was able to briefly access the bios. There is an option to always have the fan running (which is set to on) but fan definitely doesn't run. Also under diagnostics, only error returned is no hard drive. For sh*** and giggles, I tried spraying compressed air onto the fan while the laptop was running. Figured this might either :A)keep the temps in check temporarily B) allow fan to report to mobo that its actually spinning. Needless to say this didn't work. I guess it could be that the fan is completely shot and not reporting anything..
