I have a Dell Latitude D620 that was a workhorse, until one day recently, the CPU fan stopped working and the CPU started overheating. I did a little diagnosis of my own and found that the fan worked fine while plugged into a stand alone power supply. I then took the laptop into a local laptop repair shop and they diagnosed it as a bad motherboard. Of course, they wanted to sell me a refurbished motherboard for big money and I refused, knowing that I could probably find one cheaper on ebay.
I did just that and located a replacement MOBO for the D620 that was represented to be a tested and fully operational and functional MOBO by a reputable seller for about $25 w/shipping. I received it yesterday and put my CPU and other components on it and much to my surprise, the laptop fan doesn't work. Everything else appears to work fine with it (it booted up to Windows and the CPU began overheating). I tested this fan too, and it worked plugged into a stand alone power supply.
What are the odds that I could have 2 laptop motherboards with the same exact fan issue? I've researched the D620 and it doesn't appear to be a widespread problem, like the nvidia video chips on them (mine has intel video, btw). Could it be that there is something else going on, like a failing CPU? Anybody have any ideas? I really need to get some feedback before I contact the ebay seller for a return authorization and start looking at other MOBOs.
