2 days ago I got a can of compressed air and was spraying everything i could find. I sprayed the back of my Dell M170 laptop and dust came out so I thought that was good. Later I sit down on it and its going real slow so I check the CPU and it is up near 100% for most of the time. I reformat it because I think it might be a virus but it still does it right after Windows is reloaded.
I run Dells Diagnostics and it finds that the processor fan is spinning at 0 RPMs.
Error Code 3700:011B
The video fan passes.
I take apart the laptop and spray it with some air and see that the fan on the left is static and just twitches when i blow air on it. So I put a light on it and see that there is hair wrapped around the top of it, and that there is black stuff between 2 of the blades. The black stuff ended up being a wad of dust and other stuff the size of a quarter. I pull it out and the fan spins freely when i spray it with air.
I put it all back together, run diagnostics again, processor fan passes, VIDEO FAN FAILS. It spun fine when I checked it prior. Could I have messed it up without knowing while I was working on the other fan? Could diagnostics be wrong? It was testing it for FAST and it was saying it was fine but then it ended by saying it failed.
My computer is running better now, but I am worried about the "video fan".
Should I be?
